Hi All, Thanks all for your advice on the propellor. As I suspected it is fine, it is just the idiosyncracies of the AV. Was great to take her out. A little annoying that some sealife had blocked up the water seacock to the water cooling system. The water was flowing fine to start with on starting the engine and then out at sea the flow diminished. Fortunately think we spotted and remedied in good time i think. I have decided to get an auto tiller pilot for Vacherin and was wondering whether there was any recommendations as to brand and set-ups for AV's?It looks like there was an auto tiller pilot installed by a previous owner (a hole has been drilled which would have impeded access to the locker). Ideally I would like to install it without impeding access to the cockpit locker if practicable?
