Save yourself time, money and problems later on by checking the whole hull when you hook your boat out of the water for blacking

They might be an obvious item to check, but watch out for new ones being fitted and old, worn out ones being left on. The hull can rust behind them. Much better for old ones to be removed completely and then the hull to be blacked where they were.

Often forgotten at the bottom but it can become worn giving you a ‘loose’ tiller. It’s easy enough to have a bush fitted.

The number of boats we’ve been on where there’s wear here… check it now while the boat’s out of the water.

No jokes from us, the cut is littered with props so check the nut is tight and, crucially, the split pin is whole.

If you don’t have one, this is what can happen – wear on both the rudder and boat. Get one welded on.

Often forgotten, but think chemicals in washing-up liquids, so check for corrosion – unless you use Ecover.

The baseplate should protrude about 1cm, but it will wear down and if it’s flush with the hull, as can be seen here, it needs a piece adding.

You should pick this one up anyway, but look out for it, what’s caused it and maybe fit a galvanic isolator.
