Better day. Sunny if cold. No resolution to anode but fuel filter changed water seperaror too. Motored to fuel pontoon. Went for a potter. Engine ok. Removed compass for service. Couldn't free locking mechanism on steering. Not a 'must do'. Added Genoa tracks to 'to do' list - may be source of leaks.

Oh and I found the padlock that I thought was in the bilge which led to buying a new one which resulted in dropping the key and having to break into the boat!!!!!
