Has anybody any idea how long I can leave my boat in the water without having had the hull antifouled?
My plan is to have a berth in a marina on the tidal Thames for about 6 to 8 weeks. (Usually it lives on it's trailer)
The marina has a lock, so there is little water movement, and it will be there for the rest of April and May when the water is still quite cold if that makes any difference.
If it does start getting growth on the hull, is it a simple matter of pressure washing it after lift out, or does the hull get permanently stained?
