Dear all, I've got a french Beneteau First 18, a small 18 feet day cruiser; very good boat, except for very light airs (as it is a little bit heavy-800kg) So, I plan to make a very big nylon headsail to play with winds strictly <4 kn, like a big drifter or code 0 sails. * For the sail dimensions (luff, foot & leech), I took almost the maximum values minus 200-300 millimetters * For the rounds : -1% luff -1% leech + 5% feet Is this first step correct ? I'd rather take a lower leech ? I have measured the expected sheeting angle on my boat (around 9°) and I modified the twist angle to 8° to "better keep the wind", as I plan to use the sail only in light winds (Sailcut is initialized with an angle of 18° for headsails). But I'm really not sure about my correction ! For the same reasons, I have also modified the bottom profile with a higher deepth (2% changed to 5%). So now, the mold is top to bottom : 6%,8%,5% Do you think I am the right way ? Any comments are welcome, as I was unable to find reliable(or not) informations on existing litterature about this kind of sails ! Best Regards, Florent http://first18.over-blog.fr/ |
