Asymmetric Spinnaker fitment question

Got an opportunity to get a new asym spinnaker with a sock from a Catalina 30 Tall mast boat. The mast is about 1-2 feet taller than my Santana 30. Also seems to be about a foot longer on the foot and leach. With an asym spin will this be a huge issue. The price is amazingly low. I think the sail area of the sail is about 700 sq ft and the one listed for my boat is about 650 sq ft. Ideas and thoughts? Would it be a good fit? Too much power? Can I have it cut? Would it be worth it? Thanks!

Re: Asymmetric Spinnaker fitment question

If your rig is the shortest of the three rigs that were available for the Santana, then it is about 39' which is a fair amount shorter than the 43' Tall rig on the Catalina, however the J measurement on the Santana is 12'8" vs the 11'6" on the non-sprit C30. (do you know if the boat it comes off has the optional bowsprit?) Also, if the chute is cut for a sock, then it will be a bit short on the hoist to accommodate the retracted sock, which will work in your favor.


It sounds like it could be close enough in size that you can make it fit. You may want to consider a short bowsprit to get a better fit, and better sail handling.

If it is off a non-sprit C30 then it might be pretty close to the right fit. If it is off a sprit boat then you might want to try it for size before you buy. Either way odds are good you can make it work. It will be a lot of power, but will be great for lighter wind days.

edit: after doing a bit of math it looks like even with a 3' sprit the luff could still be too long. You should confirm a few things: Actual luff length of the sail, your "I" measurement, (there were 3 rigs on the Santana, 39, 40 and 41ft) and whether or not the Catalina was a sprit model or not. (w/sprit the "J" is 13'1" and w/o it is 11'6")

Re: Asymmetric Spinnaker fitment question

The used sail sites generally state that measurements within 10% up or down, in or out will work for spinnakers.

I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
