What it is
A mobile service cleaning decks, topsides, windows and interiors of leisure boats while they sit on their berths or hardstanding, using your own kit and a small van or car.
Your first three steps
- Visit two or three local marinas and harbours, and ask about their rules for outside contractors and any access fees
- Get a starter kit of boat-safe cleaning products, brushes, a pole and a pressure washer or hose setup, and arrange insurance
- Offer a discounted first clean to a few owners and ask for reviews and a place on the marina noticeboard
Who pays
Private boat owners who live far from their boat or lack the time, plus liveaboards and small syndicates.
How it makes money
Fixed price per boat based on length, or an hourly rate. Regular monthly or seasonal clean contracts give steady work, with extras like polishing or interior valets.
Skills that help
- Thorough, careful cleaning
- Comfortable working on and around water
- Reliable and trusted with other people's boats
Watch out for
- Public liability insurance, and check whether it covers work on boats and over water
- Many marinas have approved contractor lists or rules on outside traders, so check before turning up
- Use boat-safe, low-impact products and check rules on wash water draining into harbours or rivers
- Take care with gelcoat, varnish and canvas, and test products on a small area first
- Winter can be quiet in many areas, so plan for seasonal income
