Adventure Category: Boat Planning

Life aboard a narrowboat is associated with peace, tranquillity and a close connection with the surrounding landscape.

That tranquillity can disappear rather quickly when the engine starts.

As we plan Priscilla, controlling machinery noise will be an important part of creating a comfortable boat. One possible component of that work is sound-deadening paint—or, more accurately, a vibration-damping coating.

What does sound-deadening paint do?

An engine creates both airborne noise and vibration.

Vibration can pass into surrounding steel panels, causing them to resonate and radiate additional noise. A specialist damping coating adds mass and reduces some of that panel movement.

It will not silence an engine or replace proper acoustic insulation. Its principal value is treating awkward metal surfaces where conventional materials may be difficult to install.

Why consider it for a narrowboat?

Space within a narrowboat’s engine bay can be limited. Pipes, cables, access panels and irregular surfaces may leave areas where attaching acoustic sheets is impractical.

A suitable coating may offer several advantages:

• It can reach corners and uneven surfaces
• It adds relatively little bulk
• It remains permanently attached when correctly applied
• It can complement conventional acoustic insulation
• It may help reduce vibration from lightweight panels and covers

The greatest benefit is likely to come from applying it to panels prone to resonance—not simply painting every available surface.

Choosing the correct product

An ordinary decorative “soundproofing paint” is unlikely to be suitable for an engine bay.

Any coating used around propulsion machinery should be:

• Intended for vibration damping rather than merely marketed as sound absorbing
• Compatible with steel and the existing primer or paint system
• Resistant to the temperatures expected in that location
• Suitable for a marine or industrial environment
• Resistant to oil, fuel, moisture and routine cleaning
• Applied without compromising fire safety
• Approved by the boatbuilder, coating manufacturer or relevant specialist

Manufacturer instructions concerning surface preparation, thickness, curing and temperature limits must be followed carefully.

The coating should never be applied to the engine, exhaust, moving components, electrical connections, identification plates or equipment requiring heat dissipation.

Part of a complete noise-control system

Sound-deadening paint should be regarded as one layer within a broader design.

A quieter installation may also include:

Marine acoustic insulation

Fire-resistant, liquid-tight acoustic panels can absorb airborne sound and add mass to engine-bay covers and partitions. Seams and exposed edges should be properly sealed.

Flexible engine mounts

Correctly specified and maintained mounts help isolate vibration before it reaches the hull. Worn mounts or poor engine alignment can make even extensive soundproofing ineffective.

Acoustic seals

Noise can escape through surprisingly small gaps. Well-fitted deck boards, access panels and hatches may need appropriate seals, provided ventilation and drainage are not obstructed.

Exhaust design

The exhaust can be a significant source of noise. Correctly specified silencers, waterlocks or other components may substantially affect the result.

Regular maintenance

Loose panels, damaged mounts, poor alignment and worn components can all increase noise and vibration. Soundproofing should never be used to disguise a mechanical fault.

Ventilation and access must come first

Reducing noise must not restrict the air required for cooling or combustion.

The installation must retain adequate ventilation, drainage and access for inspection, servicing and emergency response. Soundproofing should not conceal fuel connections, electrical equipment or other components that require regular examination.

Fire-resistant products specifically designed for marine engine compartments are preferable to domestic acoustic foam or improvised insulation.

What sound-deadening paint cannot do

The name can create unrealistic expectations.

A damping coating will not:

• Make the engine silent
• Absorb all airborne noise
• Correct faulty engine mounts or poor alignment
• Replace acoustic panels and effective seals
• Improve the engine’s efficiency
• Prevent mechanical wear by itself

Its effectiveness will depend upon the construction of the compartment, the panels treated and the quality of the wider installation.

Planning a quieter Priscilla

For Priscilla, noise control should be designed into the boat rather than added as an afterthought.

Sound-deadening coatings may be useful on selected steel panels, particularly where space or access makes conventional materials difficult to fit. However, the best result will come from combining vibration control, marine acoustic insulation, careful sealing, suitable machinery mounts and a properly designed ventilation system.

The objective is not complete silence. It is to reduce unnecessary noise and vibration so that cruising remains part of the pleasure of being on the water.

Technical reference

Marine VHF radio is unnecessary on most of Britain’s quiet inland canals. On tidal rivers, estuaries and commercial waterways, however, it can become an important safety tool—and may sometimes be compulsory.

The precise rules depend upon the waterway, the vessel’s size and the proposed passage. Requirements should therefore always be confirmed with the relevant navigation or harbour authority before setting out.

Tidal Thames

The tidal Thames is the clearest example of a formal carriage requirement.

The Port of London Authority requires vessels measuring 13.7 metres—approximately 45 feet—or more to carry operational VHF equipment on most passages through its waters. There are limited exemptions, including for narrowboats navigating only between Brentford and Teddington.

Smaller vessels are strongly advised to carry VHF. Those without it may need to report to London Vessel Traffic Services by telephone before entering the tidal river.

At 58 feet, Priscilla would exceed the normal VHF threshold.

Tidal Trent, Yorkshire Ouse and Humber

The tidal Trent leads towards the Yorkshire Ouse and Humber Estuary, where narrowboats can encounter powerful tides, exposed water and substantial commercial traffic.

VHF is highly advisable on the tidal Trent and becomes increasingly important when travelling beyond Keadby towards Trent Falls and the Humber. Carriage requirements can vary according to the vessel and the waters entered, so the intended passage must be agreed with the relevant authorities.

Even where it is not compulsory for a particular narrowboat, travelling without VHF would remove an important means of receiving traffic information and communicating with locks, other vessels and port control.

River Severn and the Severn Estuary

VHF is recommended for more demanding passages on the tidal Severn and around the Severn Estuary, particularly when approaching Sharpness.

Sharpness Radio maintains VHF communication on Channel 13. Boats can also make some required contacts by telephone, so VHF should not be described as universally compulsory throughout the tidal Severn.

The combination of strong tides, limited stopping opportunities and commercial movements nevertheless makes it a valuable part of a properly prepared passage.

Bristol Channel and tidal River Avon

The Bristol Channel has one of the world’s largest tidal ranges and should be treated as serious coastal water.

Marine VHF is strongly recommended for narrowboats attempting passages involving the Bristol Channel, Avonmouth, Portishead or the tidal Avon. Harbour and lock facilities use VHF, although telephone alternatives may be available at some locations.

The exact equipment requirement should be confirmed as part of the passage plan.

Manchester Ship Canal

Pleasure craft must obtain permission and make advance arrangements before entering the Manchester Ship Canal.

The canal authority prefers communication by VHF because transmissions are recorded, but its published small-craft guidance also accepts mobile telephones. VHF is therefore highly desirable rather than universally mandatory for every pleasure craft passage.

Crews must still comply with the authority’s current transit conditions and remain contactable throughout the journey.

River Medway and Thames Estuary

The tidal Medway is a commercial navigation managed by Peel Ports, with Medway Vessel Traffic Services operating on VHF.

For an ordinary narrowboat, VHF is not automatically compulsory throughout the river. However, it is strongly advisable when navigating the lower Medway, approaching Sheerness or entering the Thames Estuary.

Local directions, notices to mariners and reporting requirements should be checked before travelling.

Clyde and Forth

The Clyde and Forth include commercial ports, controlled areas and busy shipping channels.

There is no simple rule requiring every leisure craft throughout both estuaries to carry VHF. Requirements and recommended channels depend upon the harbour area and proposed passage.

A narrowboat undertaking either journey should carry suitable communications equipment and consult the relevant harbour authority in advance.

Other tidal and commercial waterways

VHF may also be required or strongly recommended on parts of waterways including:

• The tidal Great Ouse
• The River Witham and approaches to the Wash
• The River Mersey
• The Ribble Link and River Douglas
• The tidal Medway and Swale
• Major harbour and port approaches

The rules are not determined merely by whether a river is tidal. Vessel length, commercial activity, local directions and the precise route can all affect the position.

Where VHF is usually unnecessary

A marine radio is not normally needed on ordinary canal journeys along waterways such as:

• The Grand Union Canal
• The Leeds and Liverpool Canal
• The Oxford Canal
• The Kennet and Avon Canal
• The Shropshire Union Canal

A charged mobile telephone is generally more useful for contacting the navigation authority or emergency services on these waterways.

VHF should not be carried casually without the necessary licensing and knowledge. The radio equipment must be appropriately licensed, and the operator must normally hold a recognised certificate such as the Short Range Certificate.

Planning for Priscilla

Priscilla will spend much of her time on waterways where VHF remains silent.

However, she is being designed with more demanding journeys in mind. A fixed, DSC-capable radio supported by a waterproof handheld unit would give us reliable communication on tidal rivers, estuaries and commercial waterways.

It is equipment we may rarely need—but on the passages where it matters, it could be indispensable.

Some of those passages form part of a much bigger plan.

For now, the destination remains our secret.

• Canal & River Trust: Sharpness Port
• Inland Waterways Association: Marine VHF guidance

For most journeys on quiet inland canals, a mobile telephone provides all the communication a narrowboat crew is likely to need.

The position changes when a boat ventures onto tidal rivers, estuaries, commercial waterways or busy port approaches. In these environments, marine VHF radio can become an important part of navigation and safety—and, in certain circumstances, a formal requirement.

As Priscilla is being designed for more ambitious cruising, VHF deserves to be considered from the outset.

Communicating with navigation authorities

Some locks, bridges, harbourmasters and vessel-traffic services communicate with boats by VHF.

A radio allows the crew to:

• Request passage through controlled structures
• Receive instructions from lock or bridge operators
• Report their position and intentions
• Hear navigation warnings and traffic information
• Follow directions during an incident

The appropriate working channel varies between waterways and locations, so it must be checked before beginning a passage.

Navigating tidal waters

Tidal rivers present risks rarely encountered on an ordinary canal.

Changing water levels, stronger currents, restricted visibility and commercial traffic can all affect the passage. VHF provides immediate communication with the organisations managing the waterway and with suitably equipped vessels nearby.

It also allows the crew to hear other radio traffic. Knowing that a large vessel is approaching a bend, bridge or narrow section can be as valuable as making a call ourselves.

Sharing the water with commercial vessels

A narrowboat is small, slow and comparatively difficult to manoeuvre when placed alongside a large commercial vessel.

The crew of a cargo vessel may have restricted visibility and require considerable distance to alter course or stop. Marine radio can help both vessels establish their intentions and avoid uncertainty.

VHF does not replace proper navigation, observation or compliance with local rules. It provides an additional source of information when the consequences of a misunderstanding may be serious.

Calling for help

In an emergency, VHF can reach the Coastguard, navigation authority and nearby vessels simultaneously.

Unlike a mobile telephone, it does not depend upon knowing the correct telephone number or having coverage from a particular mobile network. Other vessels monitoring the channel may hear the call and be close enough to assist.

VHF Channel 16 is used for distress, urgency and initial calling in maritime areas. It should not be used for general conversation, and local inland waterways may use different operational channels.

A distress call is appropriate only when there is grave and imminent danger. Training is essential so that the operator understands when and how to make Mayday, Pan-Pan and routine calls.

When is VHF compulsory?

There is no general legal requirement for every narrowboat to carry VHF radio.

Requirements depend upon the vessel, its length and the waterway being navigated. The tidal Thames is an important example: the Port of London Authority requires narrowboats measuring 13.7 metres—approximately 45 feet—or more to carry VHF on most passages through its waters. A limited exemption applies between Brentford and Teddington.

At a planned length of 58 feet, Priscilla would exceed that threshold.

Elsewhere, VHF may be recommended rather than mandatory. On the River Severn Navigation, for example, Canal & River Trust guidance advises boats carrying VHF to monitor Channel 74, but this does not amount to a universal requirement for every narrowboat on the river.

Local navigation instructions must therefore be checked for every intended route.

Fixed or handheld equipment

A permanently installed VHF radio generally offers greater range than a handheld set because it can use a higher-mounted external aerial and the boat’s electrical supply.

A waterproof handheld radio remains valuable as a backup and can be carried by a crew member working away from the steering position.

For Priscilla, the likely solution is a fixed, Digital Selective Calling-capable radio supported by at least one handheld unit.

Another part of Priscilla’s preparation

VHF would probably see little use during an ordinary cruise along a quiet rural canal.

However, Priscilla is not being planned solely around ordinary cruising.

Her communications equipment must reflect the more demanding waterways she may encounter, while giving us the training and confidence to use it properly.

We are not revealing every part of the journey yet—but we know that reliable communication will matter along the way.

Designing our future narrowboat begins with one fundamental decision: its length.

Every additional foot creates more living space, but a longer boat can restrict access to parts of the canal network and make some locks more challenging. After considering how we intend to travel and live aboard, we have chosen a 58-foot narrowboat.

For us, it offers the right balance between cruising flexibility and creating a comfortable long-term home.

Finding the right length

A length of approximately 57 feet is commonly regarded as the most versatile choice for exploring the connected inland waterway network.

We have decided to extend that slightly to 58 feet.

That additional foot may sound insignificant, but aboard a narrowboat every inch matters. It can provide valuable extra storage, improve the proportions of a room or make the difference between a compromised layout and one that works comfortably.

A 58-foot boat should remain suitable for most of the waterways we hope to explore. However, lock dimensions, water levels and local restrictions vary, so individual routes will always need to be checked carefully.

We accept that a few waterways may be inaccessible or require particularly careful handling. For us, that is a reasonable compromise in return for greater comfort during extended cruising and, eventually, full-time life aboard.

Designed for living, not occasional holidays

Our boat will not simply be somewhere to spend the occasional weekend.

We want it to become a comfortable home capable of supporting extended journeys throughout Britain and potentially farther afield. Its layout must therefore work for everyday life rather than merely looking impressive at a boat show.

The additional length will give us greater flexibility when planning the interior. It should allow us to incorporate better storage, avoid unnecessarily cramped rooms and create a boat that feels comfortable without wasting space.

A narrowboat will always require careful compromises, but thoughtful design can prevent it from feeling compromised.

An enclosed bow

One of our clearest decisions is to have an enclosed bow rather than a conventional open well deck.

Front seating can be attractive, but our experience suggests that we would use it relatively rarely. Weather, wind and the availability of better seating elsewhere aboard can leave a traditional bow area occupying valuable space without contributing much to daily life.

Enclosing this area allows us to extend the internal accommodation farther forward and create a more generous bedroom.

That matters considerably more to us.

A larger bedroom should provide better access around the bed, more practical storage and a calmer, less confined space. These are modest improvements individually, but they will make a considerable difference when living aboard for weeks or months at a time.

We would rather devote the space to something we use every day than preserve an outdoor seating area simply because it is conventional.

A square stern

At the opposite end of the boat, we intend to specify a square stern.

The stern will be one of the principal outdoor social spaces aboard. It needs to work not only when cruising but also when moored, entertaining friends or simply sitting outside and watching the world pass.

A squarer design makes more effective use of the boat’s available footprint. It can offer better seating, easier movement and additional storage compared with a heavily curved stern.

It should also provide a more practical space for the person steering and anyone joining them during the journey. Narrowboating is far more enjoyable when the helm does not become an isolated position occupied by one person while everyone else disappears inside.

The precise arrangement will need to be developed carefully with the boatbuilder. Safety, access to the controls and protection of the propulsion equipment must remain central to the design.

The objective is not simply to make the stern larger, but to ensure that every part of it serves a purpose.

Making every foot work harder

The enclosed bow and square stern reflect the same principle: space aboard must earn its place.

Rather than following a conventional narrowboat layout automatically, we want to consider how we will genuinely use each area.

Our priorities are clear:

• A comfortable bedroom suitable for long-term living
• Generous and intelligently designed storage
• A practical interior without wasted circulation space
• An outdoor seating area that we will genuinely use
• A welcoming stern where people can share the cruising experience
• A boat that remains manageable across most of the UK canal network

These priorities will guide the detailed layout as the project develops.

Balancing freedom and comfort

Choosing a boat always involves compromise.

A shorter narrowboat would offer slightly greater cruising flexibility. A longer boat would provide more internal space but progressively restrict the routes available to us.

At 58 feet, we believe we have found our balance.

It should give us enough room to create a comfortable and highly practical home while preserving access to the great majority of the journeys we want to undertake.

The enclosed bow will allow us to prioritise the bedroom. The square stern will create a more useful outdoor and social space. Together, these choices begin to define a boat shaped around our lives rather than around convention.

There are countless decisions still to make, but the foundations of the design are becoming clear.

Our future narrowboat will be 58 feet long, enclosed at the bow and square at the stern—a boat designed for travelling widely, living comfortably and making every available inch count.

By July 2023, our dream of retiring aboard a narrowboat was beginning to develop into a practical design.

We were still several years away from commissioning our boat, and Priscilla, Queen of the Canal had not yet emerged as the bold vision she would later become. At this stage, we called our imagined boat Serenity—a floating sanctuary designed around comfort, intelligent use of space and long-term life aboard.

Our earliest layout placed the bedroom at the bow, followed by a full-width bathroom, galley and lounge, leading through to a sociable square cruiser stern. Every section had a clear purpose, while storage and flexibility were built into almost every available space.

A king-sized bed at the bow

The master bedroom would occupy the forward section of the boat, creating a quiet and private retreat away from the main entrance at the stern.

At its centre would be a fixed king-sized bed, positioned as far into the bow as the shape of the hull allowed. While ambitious for a narrowboat, we wanted our future home to provide the same comfort as a conventional bedroom.

The bed would be raised approximately 700mm above the floor, creating substantial storage beneath. Pull-out drawers or wheeled storage units at the foot would make the space accessible without requiring us to lift the mattress whenever we needed something.

A built-in headboard would provide further storage, alongside integrated reading lights, electrical sockets and USB charging points. These small conveniences would help the bedroom feel properly designed rather than simply fitted into the available space.

Wardrobes and shelving opposite the foot of the bed would complete the room, with a door leading into the walkthrough bathroom.

A full-width walkthrough bathroom

Moving towards the centre of the boat, the bedroom would open into a full-width bathroom.

Using the entire width of the cabin would create a more generous room and avoid the cramped corridor arrangement found in some narrowboat layouts. Closing the doors at either end would provide complete privacy while retaining a natural route through the boat.

Frosted portholes would bring daylight into the room without compromising privacy. We imagined a fully waterproof wet-room design, making the space easier to clean and allowing the shower to occupy more of the available area.

Our preferred toilet was a Thetford ceramic cassette model. Although other systems offered advantages, cassettes provided flexibility and avoided relying entirely upon pump-out facilities.

A waterproof storage seat within the shower area would conceal spare empty cassettes. The washbasin would sit above a fitted cupboard, ensuring that even the smallest spaces contributed useful storage.

A galley designed as a proper kitchen

The galley would follow the bathroom and form the practical heart of the boat.

We favoured a U-shaped arrangement because it offered generous work surfaces and storage while keeping appliances within easy reach. As we intended the boat to become our home, the kitchen needed to support everyday cooking rather than merely occasional holiday meals.

Our early equipment list included:

• An induction hob
• A conventional oven
• A combination steam and microwave oven
• A full-sized fridge
• A separate freezer
• A washer-dryer

Choosing electrical appliances reflected our early interest in an all-electric boat. It would require careful planning around batteries, charging and power generation, but we wanted to explore what might become possible as marine electrical technology developed.

Breakfast with the canal outside

A breakfast bar would provide our principal dining space without requiring room for a separate table.

Positioned between a pair of side hatches, it would allow us to sit with the doors open and enjoy uninterrupted views across the canal. It could also serve as additional preparation space, a desk or somewhere to plan the next day’s journey.

We wanted the internal faces of the hatches to display the plaques collected during our travels. Embedding them into the woodwork would turn a familiar boating tradition into part of the interior design, revealed whenever the hatches were opened.

One of our more unusual ideas involved glazed inner panels that could slide vertically into the gunwales. These would allow light and views into the galley while providing protection when conditions were too cold or windy for completely open hatches.

It was an ambitious detail, but exactly the sort of idea we wanted to investigate before settling upon a final design.

A flexible and spacious lounge

Beyond the galley, the lounge would provide our main place to relax, entertain guests and enjoy quieter evenings aboard.

The television would be mounted high on the wall between the windows, keeping the floor and walkway clear. Seating would face towards it while still allowing us to enjoy views through the windows and glazed stern door.

A generously sized sofa bed would offer comfortable everyday seating and convert into accommodation for visitors. Finding a model capable of fitting through a narrowboat doorway—and functioning properly once inside—would inevitably require careful measurement.

The lounge needed to feel open rather than crowded. Furniture would therefore have to earn its place by offering storage, flexibility or more than one function.

Connecting the lounge and stern

A half-width glazed door on the starboard side would connect the lounge with the rear deck.

Positioning the door to one side, rather than centrally, would create a more usable wall within the lounge and preserve a clear route through the boat. The glazing would bring additional light inside and allow us to enjoy the view even when the weather kept the doors closed.

When open, it would help the lounge and stern feel like one continuous entertaining space.

A square cruiser stern

At the rear of the boat, we imagined a square cruiser stern with built-in seating.

Traditional cruiser sterns provide valuable outdoor space, but their curved edges can restrict seating and make the deck feel smaller than it is. A squared design would create a more defined social area and make better use of the boat’s footprint.

Integrated seating would offer somewhere for friends to gather while cruising or moored. Storage beneath could accommodate ropes, outdoor equipment and other boating essentials.

This would be more than the place from which we steered. It would become an outdoor lounge: somewhere to enjoy breakfast, share drinks with friends and watch the canal disappear behind us.

Designing for life, not just holidays

Our first layout was not intended for a conventional holiday boat.

We were beginning to design a full-time home that needed to remain comfortable through changing seasons and changing stages of our lives. Storage, accessibility, electrical capacity and ease of movement mattered just as much as colours, finishes and furniture.

Some of these early ideas would inevitably change. Technology would develop, our priorities would evolve and every boatbuilder would bring different possibilities and constraints.

That was part of the value of beginning early. We had time to question each assumption, learn from existing boaters and gradually distinguish the essentials from the attractive ideas that might not survive contact with reality.

From Serenity towards Priscilla

Looking back, this design represented an important step in our journey.

Serenity was the working title for a calm, comfortable retirement home. The later vision for Priscilla, Queen of the Canal would become bolder, more distinctive and more ambitious, but many of the underlying principles began here.

The king-sized bed, generous bathroom, capable galley, flexible lounge and sociable stern all reflected the life we wanted to create: comfortable, adventurous and unmistakably our own.

The final boat might eventually look very different, but this was where we first began transforming an idea into a layout—and a distant dream into something we could imagine calling home.
