New narrowboat buying guide

From the first idea to a boat built around your life

Buying a new narrowboat is not simply a choice of length, layout and colour. The best result comes from understanding how you will use the boat, choosing a builder whose work you can verify and turning every important promise into a clear written specification.

This guide explains the decisions to make before reserving a build, the questions to ask and the evidence you should expect to see before handover.

Oakums designs and builds new Open Bow, Closed Bow and Bowless narrowboats with diesel or electric propulsion. More than 50 Oakums boats are now on the inland waterways.

1. Decide how you will use the boat

Begin with real life aboard rather than a list of equipment.

Ask yourself:

• Will the boat be used for weekends, holidays, extended cruising or living aboard?
• How many people need permanent and occasional berths?
• Do you expect to work remotely?
• Will you have a permanent mooring with shore power?
• Will you cruise throughout winter?
• Which waterways do you want to explore?
• How important are outdoor space, storage and separate rooms?
• Which domestic appliances do you genuinely expect to use?

These answers affect the length, layout, heating, electrical system, water storage, propulsion and budget. A boat designed for regular marina use has different priorities from one intended for year-round continuous cruising.

2. Set a complete budget

The advertised starting price is only the beginning of the decision. Establish what is included and what sits outside the build price.

Allow for:

• Agreed boat specification and optional upgrades
• Design changes after the specification is signed
• Mooring or continuous-cruising arrangements
• Insurance
• Licensing
• Fuel or charging
• Routine servicing and consumables
• Blacking, painting and longer-term maintenance
• Equipment and personal items not included in the contract
• Survey or independent advice where chosen
• Delivery, cranage or transport if applicable

Current Oakums starting prices are:

Final cost depends on length, propulsion, layout, equipment, materials and specification. Obtain a written, itemised quotation rather than relying on an informal conversation.

3. Choose the right length

A longer narrowboat can provide more accommodation and storage, but it also changes price, handling, mooring requirements and access to parts of the canal network.

Consider:

• Number of permanent beds
• Separate bedroom requirements
• Bathroom arrangement
• Galley and saloon proportions
• Workspace
• Utility and technical storage
• Outdoor deck preference
• Intended waterways and lock dimensions
• Mooring availability and charges

Do not add length without deciding what each additional area is meant to achieve. A carefully planned smaller boat can feel more useful than a longer boat with poorly balanced spaces.

4. Compare layout types

Open Bow

An Open Bow provides a forward outdoor seating and access area. It suits buyers who value time outside, views along the water and a sociable connection between interior and exterior.

Closed Bow

A Closed Bow brings the forward area inside the accommodation. It can create additional private sleeping, office, storage or flexible living space.

Bowless

The Bowless is Oakums' 40ft range. By removing the conventional bow, more of the boat's overall length becomes usable internal space, making it the most spacious 40ft narrowboat in its class compared with conventional designs from other manufacturers.

The correct layout depends on how often the outdoor area will be used, how much private accommodation is required and what compromises are acceptable.

5. Decide between diesel and electric propulsion

Diesel remains familiar, flexible and lower in initial cost. Electric propulsion provides quiet, smooth cruising but requires a complete energy plan covering battery storage, shore power, solar and any alternative charging source.

Do not choose electric from the motor rating alone. The design should account for:

• Typical cruising hours and conditions
• Domestic electrical demand
• Battery capacity and usable reserve
• Charger and inverter limits
• Shore-power availability
• Seasonal solar generation
• Winter operation
• Whether a diesel generator is acceptable
• Technical support after handover

Electric propulsion does not always mean a diesel-free boat. Some installations use a generator, changing how and when diesel is consumed rather than removing it completely.

6. Understand what sits behind the finish

The visible interior represents only part of the boat. Ask about the materials and access behind it.

Important areas include:

• Hull specification and preparation
• Insulation
• Ballast and subfloor
• Wall and ceiling construction
• Plumbing routes and isolation points
• Cable routes and protection
• Ventilation
• Heating installation
• Access for future servicing
• Cabinet and partition materials

Oakums uses marine plywood rather than MDF or chipboard. Material choices should be recorded in the specification rather than left as an assumption.

7. Design the electrical system around real demand

Create a realistic list of domestic loads, including refrigeration, cooking, washing, hot water, pumps, lighting, entertainment and remote-working equipment.

The system must balance:

• Daily consumption
• Battery storage
• Charging rate
• Shore supply
• Solar capacity and seasonal yield
• Generator contribution where fitted
• Propulsion demand on an electric boat
• Monitoring and fault diagnosis

A larger battery does not solve a weak charging plan. A larger generator does not automatically increase charging speed if the inverter-charger cannot accept the additional output.

Ask for the assumptions behind any energy calculation.

8. Agree the specification in writing

The specification should be detailed enough for both buyer and builder to understand what will be delivered.

It should identify, where applicable:

• Boat length and range
• Hull builder and principal dimensions
• Propulsion system
• Battery, inverter, charger and solar equipment
• Heating and hot-water systems
• Water and waste arrangements
• Layout and berth sizes
• Cabinet materials and finishes
• Flooring, worktops and upholstery
• Appliances
• Windows, rooflights and exterior access
• Painting and exterior finish
• Safety and compliance documentation
• Items specifically excluded

Avoid phrases such as “standard specification” unless the referenced standard is attached, dated and incorporated into the agreement.

9. Read the build contract carefully

The contract should match the specification and describe how the project will be managed.

Check:

• Contracting legal entity
• Total price and tax treatment
• Deposit and payment stages
• What evidence triggers each payment
• Expected programme and how delays are handled
• Ownership of the boat, materials and equipment during construction
• Insurance responsibilities
• Process for buyer-requested changes
• How additional work is priced and approved
• Inspection arrangements
• Cancellation and termination terms
• Completion, acceptance and handover process
• Warranty and aftercare terms
• Dispute-resolution process

Take independent legal advice if anything important is unclear. This guide is practical information, not legal advice.

10. Control changes during the build

Changes are sometimes necessary, but informal changes create uncertainty.

For every amendment, record:

• Exact change requested
• Price increase or reduction
• Effect on the programme
• Effect on other parts of the specification
• Buyer and builder approval

Keep a single current specification and change record. Do not rely on scattered messages to define the finished boat.

11. Follow the build without disrupting it

Agree how updates and visits will work before construction begins.

Useful evidence can include:

• Dated progress photographs
• Stage meetings
• Updated drawings
• Equipment schedules
• Written change approvals
• Testing records

Photographs are helpful, but they do not replace inspection, documentation or an accurate specification.

12. Check compliance and documentation

New recreational craft placed on the market in Great Britain fall within a product-safety framework that includes the Recreational Craft Regulations 2017. The exact duties and conformity route depend on the boat and circumstances.

Before handover, ask the builder to identify the applicable conformity route and the documents that will be supplied. Depending on the boat, the handover pack may include:

• Declaration of conformity or other applicable conformity documentation
• Owner's manual
• Craft identification and builder information
• System instructions and warranties
• Electrical diagrams
• Gas documentation where relevant
• Equipment manuals
• Commissioning and test records
• Bill of sale and payment record
• Keys, access tools and emergency information

Licensing, insurance and Boat Safety Scheme requirements are separate matters. GOV.UK states that a BSS certificate may be needed before a boat can be registered or licensed on inland waterways. Confirm the current requirements with the relevant navigation authority for the intended waterway.

13. Prepare for handover

Do not treat handover as a quick exchange of keys.

Allow time to:

• Inspect the boat against the written specification
• Record agreed outstanding items
• Operate the propulsion and steering controls
• Understand shore power and charging
• Review battery and system monitoring
• Use heating, hot water and pumps
• Locate isolation switches, breakers and valves
• Understand toilet and waste systems
• Review routine maintenance
• Receive all documents and manuals
• Confirm warranty and aftercare contacts

Ask for unfamiliar systems to be demonstrated rather than assuming they will be obvious later.

14. Plan the first weeks of ownership

The first trips should create time to learn the boat and identify questions.

Before setting off, confirm:

• Insurance and licensing
• Mooring or cruising plan
• Required safety equipment
• Fuel or charging plan
• Water and waste arrangements
• Basic tools and spares
• Emergency contacts
• Maintenance schedule

Keep a written list of observations and distinguish genuine defects from changes of preference or later additions.
