Aaron and I went out to the boat at its mooring. Aaron sealed a leak in the propeller tube coupling and added a float switch to the aft bilge pump. I put on my wetsuit and snorkeled on the mooring block. It was low tide so it was only 400mm deep. The bottom is mud and the consistency of custard, so I got pretty dirty. The chain which I had to dig out of the mud was in excellent condition, so I just replaced the rope. snorkelling on the mooring paddling out to the boat
