Keel is an Important Factor
Our 1988 Legend 35 has a bulb-wing keel with a draft of 4'-6" while the 40.5 bulb-wing keel has a draft of 4'-10", an increase of only 4-inches. The 40.5 is a larger boat than the 35 so the deepest point of the hull is probably just about 4-inches lower than on the 35. What this means is that the vertical height of the keel on the 40.5 is nearly the same as on the 35 and therefore less efficient if all other factors are in proportion.We have sailed a few races in Pudget Sound with a PHRF of 123 with Max-prop, spinnaker, backstay adjuster, and Pettit Trinidad bottom paint. The 150 is a triradial Norlam and a couple years ago we bought new North Dacron cruising sails. All other items are basically OEM. More sheet stoppers and larger primaries have been added but nothing that is "go-fast" or that will increase speed. The main halyard is 9/16 vice the OEM 1/2 inch line but pretty much the low-tech stuff. We participated in one very light air PHRF race in '91 and placed 4th in our class behind a couple top 25 boats, a C&C 34 (was rated #1 in Puget Sound) and a Hobbie 33 (good light air boat) - not bad. We probably would have placed 3rd except that the race committee didn't call our finish until we were well over the line because we didn't have sail numbers and they thought we were crashing their party. Three seconds would have put us in third. A comment by one of the race committee members with regard to our rating was "they didn't do you no favors". Our placing had more to do with tactics than sailing ability. Because of what I thought was a poor number we gave up racing.In '99 we participated in the club bear can series and placed 4th out of about a dozen boats. In on of the races, a drifter, the transmission wasn't placed into reverse to feather the prop until the last leg and it made a real difference. With the equivalent of a fixed prop the boat doesn't point very well and has too much side slip for competitive racing. It was very apparent when sailing close with competitors which we know how they track that a small amount of drag has a big influence on tracking ability. The racing results with other boats with Petit Trinidad type paint revealed we finished really close, often only seconds out of the next place and usually not more than 2 or 3 minutes out of first. I usually sailed with only one crew (no flying sails), sometimes with none and once with three - saves weight and with a dodger there isn't room to move anyhow. What was nice is that everybody commented how well the boat performed.What I deduce from this is that the 40.5 keel will have a similar effect, that is, not enough cross section area for the size of boat. The 35 is 12,600 lbs while the 40.5 is somewhere around 20,000 lbs. It's my gut feel that if the 40.5 keel was deeper the boat would not side-slip as much and would track better.The comments by Ron Barrows with regard to smooth bottom paint and faired bottom are right on. Boats with slick and faired bottoms go much faster. A J-36 which is tricked out literally will walk away from us. The really competitive boat will have all the gear you have plus a slick and faired bottom, and have it dived on for cleaning before each race. Take everything off the boat such as mattresses, food, dishes, use minimum ground tackle (six feet 1/4-inch chain and 100 feet of 1/2-inch rode if fine!), Honda battery for engine starting, no refrigeration, etc., etc. and you'll definitely improve your standings. One guy that I sailed against has a porta potti (no fixed head or holding tank) and the boat rule is the person who uses it has to empty it. These are the kind of people who consistently finish near the top. One doesn't expect a boat with four golfcarts, a group 28 start battery, Avon 3.15 roll-up dingy, 8hp outboard, spare parts for everything, tools, extra storm ground tackle, etc., to do that well.
