paxfish 5 Posted May 30, 2017 Share Posted May 30, 2017 Guys - Take a quick look at this and tell me what you think of this screecher. It is a very light mylar laminate. I sort of guessed at dimensions, fabric etc. Comments on rigging, luff etc are appreciated.... https://youtu.be/Kwxgns1rIk0 Quote Link to post Share on other sites

paxfish 5 Posted May 30, 2017 Author Share Posted May 30, 2017 Hmm - Did I have it cut too small you think? Or are you thinking a fuller cut would have made more sense? Quote Link to post Share on other sites
TimB 7 Posted May 31, 2017 Share Posted May 31, 2017 I think he means it could be bigger, maybe with the clew back near the rear beam! This is NZ style sarcasm disguised as wit. Quote Link to post Share on other sites
Clipper 375 Posted May 31, 2017 Share Posted May 31, 2017 Size doesnt look too bad, heres mine, sheeted in tight to sneak up to an upwind finish Quote Link to post Share on other sites
ScottiE 174 Posted May 31, 2017 Share Posted May 31, 2017 yeh - didn't think it looked too bad - pretty similar shape to Voom's - just your prod is not quite as long. It's usually the m/h gennes that sheet to the aft beam Quote Link to post Share on other sites
paxfish 5 Posted May 31, 2017 Author Share Posted May 31, 2017 Thanks Gents! That is very helpful. Looks like I got pretty close. I can definitely grab more wind and carry it down with good boat speed. What does your luff look like? I'm debating whether I need to rig a 4:1 tack to increase luff tension, but I'm not sure what an optimal luff would be for a sail like this. The luff line is 6mm Dyneema and thus should be able to take a load. However, if I head up a bit high, and luff the luff, it responds with a loud CRACK! when I fall off. I would like to minimize this because of the shock on the very light fabric. It is two layers of .75 Mylar with a grid of Twaron fibers in between. As info, the prod is 2 meters long.

Clipper 375 Posted May 31, 2017 Share Posted May 31, 2017 The loud crack is something i experienced with my old screecher. I always thought it was lack of luff tension that caused it. I have a normal 1:1 halyard, which I haul to the top. then i use a 2:1 tackline onto a winch. we winch until too scared to winch any more. I believe you should have as much tension as you can on the luff. Quote Link to post Share on other sites
paxfish 5 Posted May 31, 2017 Author Share Posted May 31, 2017 Good points! Also I don't have running backs, and really do not want to invert my mast or something crazy like that.... Quote Link to post Share on other sites
Clipper 375 Posted May 31, 2017 Share Posted May 31, 2017 Yeah, watch the mast, keep main sheet on tightish to help support it maybe. I have backstays so am pretty comfortable easing the main. Quote Link to post Share on other sites
B00B00 330 Posted May 31, 2017 Share Posted May 31, 2017 You might need to tighten/shorten the luff cable. If the cable is set too loose you get that real whip loading but if the cable is taking the load then the luff should just hang off the cable and luff more like a headsail attached to a forestay. You should be able to adjust the cable length either at the tack or head with a lashing. They often require a fair bit of adjusting to get set just right. If in doubt make the cable shorter that you think. Quote Link to post Share on other sites
