i have just bought a second hand 7.5 neil pryde helium 2008 & i have only used it once & when i rigged it i didnt seem to get the loose leech that i normally get when rigging my other sails & as im having trouble finding a rigging guide for this sail on the web i thought i would ask the experts thank you in advance

Except for the race sails, the NP website shows only one rigging guide for 2008 flatwater sails, shown here: http://www.neilpryde.com/images/en/downloads/ws_rigging_guide_2008_en.pdf.

If you have the correct mast and the correct mast extension, would suggest that you experiment to get the power you need by varying the amount of downhaul and the amount of outhaul (minimum downhaul + minimum outhaul = power and vice versa)

Hope this helps.

I have the 2008 8.5 and set it always to the stated downhaul (and yes it does have a tight leech) and only make changes to the outhaul. I've found if you over downhaul this sail it just kills it, you can control it through outhaul alone, sometimes extending the boom by up to 4cm. When overpowerd this sail is very backhanded and top heavy and i've found nothing will fix this, Just make your harness lines are a bit wider then normal and this helps when overpowered. When in the right condition (10-12knots) and attached to a superlight wind It's a dream to sail.

I'm think I found a helium rigging guide on itunes once, I'm sure it would still be there..If not try the Pryde website.

Cheers

ive got a 465 arrows lance ten icms 25 moby
the sail worked great i keeped up with a couple of starbord goes on an old bombora i just wasnt sure about no loose leech
jh im on the maximum extension on my boom now at 220 could i drill a couple more holes to get extra or would i be pushing it to much
much appriecated thanks

the helium has no loose leech whatsoever built only for light 8-12kts but didn't really take off as a really good sail but will get you planing sooner..anything faster or stronger you don't have top end as the sail becomes a drag
