Any tips on sail trim on the 23.5? We can't seem to get any twist in the main. When the wind picks up it would be nice to be able to dump some wind at the top of the sail. How do you all position the jib on a reach? Ours seems like its trimmed too tight on a reach, but we can't let it out much without it flapping around. Sorry if these seem to be real newbe questions, but I can't seem to get the sail shape that I see on other boats. thanks, Rich

Main

To depower your main in heavy wheather tension the halyard, outhaul, and vang. This will flatten the sail and help depower it. If still over powered put in a reef. Hope this helps

Mainsail twist

Mainsail twist is controlled by the tension in the leech (trailing edge of the sail). More leech tension means less twist (and more power). Reduce the leech tension to increase twist in heavy air. Leech tension is primarily controlled by the mainsheet, boom vang, backstay and leech cord (small-diameter line in the leech of the sail itself that is cleated on the sail near the clew). The first two controls pull down on the boom. More mainsheet or vang tension puts more downward pull on the boom, tensioning the leech. The backstay bends the middle of the mast forward and the top of the mast back. More backstay tension in heavy air does two good things at once; flattens the sail and loosens the leech. The leech cord tensions the leech independently of the other controls and should be loose in heavy air. The recommended setup for heavy air is to tighten everything except the leech cord. Easing the mainsheet or the traveler in the gusts also helps to depower the mainsail. These suggestions are based on the assumption that your rig is properly adjusted. If the mast does not have enough rake and pre-bend, you might not get the full range of sail adjustment that the running rigging should provide. Check with someone who knows the correct rig settings for your boat. Good luck. Peter h23 "Raven"

If you have a 235 you know your boat is different because you do not have a backstay. I think Hunter calls this a B

If you have no backstay...

...then you have to adjust the mast bend with shroud tension. Increase tension in the uppers and reduce tension in the lowers to put more bend into the mast. I am assuming that your spreaders are swept back. Even if they're not, the chainplates should be aft of the mast base if you have no backstay. Again, try to find someone who has done this so they can give you an idea of how much rake and bend your mast should have. Good luck. Peter H23 "Raven"
