I bought one from......
.....Cruisingdirect.com........ go to the link below for sizing and price information. Or call their toll free number and they'll give you the info for your boat.. I'm very happy with mine, I use it quite a bit in the light airs of San Diego. For my Cat 27 the sail and dousing sock was about $800 with shipping. You'd probably need the next size down, which would put it in the $600 range. If you buy the stock sizes they ship right away, you'll have in within a week. If you want a custom size I'll take a lot longer and cost a lot more.
