Sailing the 30+
First, to discuss the 28-I am shocked to hear they are using a 180% genoa for a couple of reasons..
1). Neither the inboard or outboard track are far enough aft to lead a 180% headsail..The inside track is barely long enough for a 150, and only as long as the clew is not too high above the deck. Many people add another 8-10" so they can use a 153-155% genoa, and have some adjustability to drop the lead back at the upper end of the sail's range. The outside track ends even farther forward, so I cannot see how a 180 will ever sheet even close to correctly...
2). Because the 28 is a somewhat tender design, the boat will be WAY overpowered with a 180 (even if it could sheet correctly) by the time you have about 10 KTWS...
For your boat, if you are buying a 150, be sure the sailmaker designs the clew height so you can have full adjustment of the lead position for the entire range of the sail-I don't have the numbers committed to memory, but I think it must be no more than 10" above deck to allow it to sheet correctly when in the mid range of the sail, and still be able to drop it back as you reach the top end. If you run out of track at the top end, you will be backwinding the main excessively and heeling too much (since the genoa leech cannot be "opened" enough by moving the lead aft). Car/Lead position is critical for optimal performance.
For upwind racing, ALWAYS use the inside track (except maybe in extreme conditions and big seas). When cracked off on a reach, you should set up a lead using the outside track (barber hauler)-what I do is put a block on the outboard rail and use a second sheet (even the tail of the original genoa sheet), so you have sheets going to both tracks. By using a spare winch, you can progressively move the clew outoard as the sailing angle gets wider-to the point where once the AWA reaches about 80 degrees or so you are entirely on the outboard lead. Just remember to take off the outboard sheet before you tack!
For your 135, if it is hitting the spreader tip (it should be just touching when sheeted in correctly and in the correct wind range for this sail), first, be sure your car is in the right spot. You can check by sailing along with the sail sheeted in going upwind. Slowly begin to luff (heading up) until the inside telltales begin to break. If the lead is in the perfect spot, the top and bottom sets will break at the same time. But in the conditions where a 135 is desired, I usually set the car just an inch aft of this so the top telltale breaks justs a second before the lowers. This way you are assured of not having the lead too far forward, which is very slow-especially in these conditions. Better slightly aft than too far fwd.
If you have done all this and the leech is mashed horribly into the spreader, you may have to have the leech hollowed out by your sailmaker to allow it to fit better, but do not try to solve this by going to the outboard lead-you are giving up too much upwind performance. When overpowered, do not be shy about dropping the car aft to depower the headsail-this is very effective, and will also help with the leech hitting the spreader..
BUT-with a 150 or 135, if trimmed correctly (and built correctly), the leech should be 1-2" off the spreader tip at the bottom wind range of these sails, and just touching the spreader tip in the mid-upper range..Generally speaking, stay on the inboard track unless you are cracked off on a reach..
If you want, post some pics of the sheet position and spreader tip-I might be able to see what is going on..
Hope this helps. Yep-that was my Playboy!
Cheers,
