What it is
Hands-on boat care at the owner's berth or boatyard: washing, hull and deck cleaning, compounding and polishing gelcoat, applying wax or sealant, and cleaning interiors and canvas.
Your first three steps
- Practise on a friend's boat or a cheap project boat, then photograph before and after results
- Visit local marinas and boatyards to ask about their rules for outside contractors and which ones you could work from
- Price jobs by boat length, then message owners and brokers through marina notice boards and local boating Facebook groups
Who pays
Private owners of motor boats, sailing yachts and narrowboats, plus brokers and small dealers who need boats presented for sale.
How it makes money
Fixed price by boat length for each service, or a day rate for bigger jobs. Regular wash and wax plans bring repeat income, with seasonal deep cleans as extras.
Skills that help
- Patience and an eye for detail
- Comfortable using polishing machines
- Working outdoors and around water
- Friendly, reliable customer service
Watch out for
- Public liability insurance, ideally covering work on other people's boats and at marinas
- Many marinas and yards have their own contractor rules, insurance requirements or approved lists, so check before turning up
- Check which products are allowed near water, as some marinas restrict harsh chemicals and washing run-off
- Safe working on pontoons, ladders and in confined cabins
- Work is seasonal in many areas, so plan for quieter winter months
