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

  1. Practise on a friend's boat or a cheap project boat, then photograph before and after results
  2. Visit local marinas and boatyards to ask about their rules for outside contractors and which ones you could work from
  3. 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.
