A few more suggestions
To take a cruising boat and race it for all it's worth is quite an ambitious project. Although it is relatively straightforward to think of ways to make the boat faster (if that is all you want) it is a lot harder to weigh the penalties used by the various handicapping rules against the expected net gain in speed. In other words: to know what to do to a boat in order to sail faster is relatively easy; to know what to do to a boat in order to WIN (on corrected time) is a whole different ballgame. In fact, although we have some very competent racers on this board you might also want to post to the usenet group <rec.boats.racing> for advice if winning is your primary goal.The basic issues are, of course, maximizing DRIVE and minimizing DRAG. The only way to maximize drive is to get the best sails you can afford and learn how to use them right (including how to tune the rigging).Minimizing drag is a beast with many different heads. Keeping the hull clean has already been mentioned. Also make sure you have a folding or feathering propellor (unless the handicapping penalty....etc.) Then keep the weight either out of the boat or place heavy items as low as possible while keeping the vessel "on it's feet" (i.e. moving with minimum heel). To reduce weight in a cruising boat, remove any accessories, tools and supplies that you don't really need during the race and, especially, make sure your water, diesel and waste tanks are nearly empty (unless that causes critical balance problems). If the rules allow that, you can even put your drinking water in a few big jerrycans that can be moved from one side to the cabin to the other (and strapped down) on the different tacks while doing same with heavy toolboxes, etc. On one short offshore passage (Ensenada to Guadeloupe) in 1995 we left port with a slight list to starboard because of uneven stowage and tankage. Before we had time to worry about that, we got 25 knot NNW beam winds and found ourselves averaging 9-10 knots on a starboard tack the whole way to Guadeloupe (with a heavily loaded cruising boat!). It helped , no doubt, that we had a clean bottom and fairly new sails. However, as soon as we went to port tack to sail around the island we heeled badly and couldn't make any decent speed because of our uneven ballasting.Have fun!Flying Dutchman"Rivendel II", Legend 43 (hull #1)
