What you'll do

Day-to-day tasks

As a boat builder, you could:

  • plan out work in line with design instructions
  • create decks and hulls from fibreglass and laminates
  • make and assemble wooden furniture and fittings
  • join boat sections using welding equipment or resins
  • service and repair engines
  • refit vessels, for example with new electrics or plumbing
  • install navigation and communications equipment
  • apply finishes using varnishes and paints
  • carry out safety and quality checks

Working environment

You could work in a workshop, at a marina or at a shipyard.

Your working environment may be physically demanding, at height and outdoors in all weathers.

You may need to wear protective clothing.

Career path and progression

With experience and qualifications, you could become a marine technician or engineer.

You could also move into:

  • boat design
  • marine surveying
  • boat yard management
  • maritime sales and support

You could use your skills to transfer to other branches of engineering or into construction.

What it takes

Skills and knowledge

You'll need:

  • knowledge of engineering science and technology
  • design skills and knowledge
  • maths knowledge
  • to be thorough and pay attention to detail
  • analytical thinking skills
  • the ability to learn through your work
  • excellent verbal communication skills
  • persistence and determination
  • to be able to use a computer and the main software packages competently

Most relevant

  • Design and Technology - Boat builders work with a wide range of materials – wood, fibreglass, laminates, and metals – to construct hulls, decks, and fittings. They read design plans, use hand and power tools daily, and need to understand how different materials behave when shaped, joined, and finished.
  • Engineering - Boat builders apply engineering principles when assembling structural components, servicing engines, and installing mechanical systems. Understanding how forces, loads, and materials interact is essential for building vessels that are safe and seaworthy.
  • Mathematics - Boat builders use maths constantly – measuring dimensions, calculating material quantities, working out angles for hull shapes, and interpreting technical drawings. Precision is critical because even small errors can affect a vessel's performance and safety.
  • Physics - Boat builders need to understand buoyancy, fluid dynamics, and how forces act on a vessel in water. Knowledge of mechanics and materials science helps them choose the right construction methods and ensure boats are structurally sound.

Also relevant

  • Electronics - Boat builders install navigation systems, communications equipment, and electrical control panels. Understanding how electronic circuits and sensors work helps when wiring up and troubleshooting these systems on board.
  • Chemistry - Boat builders work with resins, laminates, fibreglass, paints, and varnishes – all of which involve chemical processes like curing and bonding. Understanding how these materials react and set helps them achieve strong, durable finishes.
  • Art and Design - Boat builders craft wooden furniture and fittings, and apply decorative finishes to vessels. A good eye for proportion, form, and visual detail helps when producing high-quality interior and exterior work, especially on bespoke or luxury boats.
  • Business - Boat builders can progress into boat yard management or maritime sales and support. Understanding how to manage budgets, price jobs, and deal with clients is valuable, particularly for those running their own workshops or small yards.

How to become

You can get into this job through:

  • a college course
  • an apprenticeship
  • applying directly
  • a course with a commercial training provider

You could take a college course to learn some of the skills you would need as a trainee, or to join an apprenticeship.

Courses include:

  • boat building
  • marine engineering
  • marine electrical engineering
  • T Level in Engineering, Manufacturing, Processing and Control
  • T level in Maintenance, Installation and Repair

Entry requirements

Entry requirements for these courses vary.

More Information

You could apply to do a Level 3 Advanced Apprenticeship, for example:

  • Boatbuilder
  • Maritime Mechanical Fitter
  • Maritime Electrical Fitter
  • Maritime Pipeworker
  • Marine Engineer

These can take between 3 and 4 years to complete. You'll do on-the-job training and spend time with a college or training provider.

Entry requirements

You'll usually need:

  • 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, including English and maths, for an advanced apprenticeship

More Information

You can apply directly if you've got relevant skills. Qualifications and experience in joinery, electrics, engineering, welding or plumbing can help.

You may be able to take a course with a commercial boat building training provider. Training can range from short courses in marine electrics and joinery, through to full boat building programmes, lasting several months.

Career tips

You'll need to be willing to move if necessary, as training providers and boat yards are located in coastal areas around the country.
