Anti corrosion tip
This one may well be known to some of the salty sea dogs out there, but I didn't and thought it quite a useful one;
When the boat is being kept at sea, or going into storage, turn the engine fully to the left. This then keeps the engine's steering bar tucked inside it's protective casing and shrouded in grease, rather than leaving it out and exposed to the elements.
Just got back from a short holiday on Belle Ile - good crossing if a little choppy, all 14 miles of it. Cruised at about 20 knots due to chop, and as waves were coming from the side, the passengers at the rear got a little wet! 1.5nm per litre. Max speed 38.5 knots. Fantastic place to visit with a RIB, it's like having all of Cornwall condensed into a (big) island, but sunny.....
