I usually sail with 4 for short course stuff. I have sailed with 5 when it was blowing 25+ and it makes a huge difference.
Mine is Audrey hull number 764
any tips on halyard tension for the jib? I need a new cam cleat and or re reoute the halyard as it loses tension during normal sailing...
Halyard tension will depend on your sails. The J24s like a loose luff, but I'm not sold on the merit liking the same. The jib on the merit is a good bit larger than the 24 as well. I've added Lewmar D1 clutches to my boat and a mast cleat for the spin hal. The spin halyard also has a clutch for tighter reaching longer legs.
is yours free to adjust like this or do you set it and adjust forestay sag accordingly?
I adjust the jib halyard with a cabin top winch. Cam cleats aren't really intended to be used for halyards. The loads are too high.
unlike other boats I have had including racing a j24 the merit is disntinguished in that it calls for forestay tightening in a breeze in combination with good backstay adjustment
I usually set the forestay length as long as I can get it without too much weather helm for the conditions. The rig likes a lot of rake in it. Pin to pin measurement should be around 30'-6". Shorter for more breeze, and maybe a little longer for lighter stuff.
what method to you use to tighten forestay turnbuckle?
I use a wrench and screwdriver or spike at the dock. My forestay is not adjustable on the fly. Does it make a difference, yes, but I'm not ready to commit to an adjustable forestay. Lots of other things to get right before controlling rake on the fly is the reason you're losing races.
btw Im loving my foil luffs...mand its beatiful to see such great shape and curve down the luff...
Only way to go in my opinion. I've been happy with mine as well.
