I have been flying both sym and asym spinnakers on Windburn for the last few years. A small tack point has been added on the bow forward of everything for the asym. I found that using an oversized pole works better, maybe a C&C 30-1 thing. Pulling the pole back a bit and getting some more chute in front generates way more power than centerline tacking. Enough of a difference to make up for sailing a bit deeper.
The largest chutes are 195%, about a 26.5' foot on the asym, and 26.3' max girth on the sym. The load on the guy is high so the line runs through a snatch block to the primary winch. It is a Samson line with a no stretch core, normal good double braid was a problem. At higher wind speeds the force back through the spinnaker pole has to be hundreds of pounds. I upgraded the spin track and car to the midsize Harken series. Even with that it is dicey adjusting the height while flying. The Torlon bearings appear to go slightly oval each season so that is on the winter maintence replace list. When flying the asym at 100 degrees AWA or tighter in heavier winds the genoa does not depower the spinnaker for take down. If it gets even slightly away from you it will fill, sometimes pretty violently. I am glad the 30-1 is so heavily over built.

Wednesday night in light air I beat him to the windward mark by a minute or two, then he hoisted his asym and dropped me like a bad habit. He beat me by five minutes corrected time in a one-hour race despite spotting me 12 sec/mile with his new adjusted rating (demonstrating yet again that ratings don’t necessarily account for performance differences). It was an eye-opening demonstration. So now I’m thinking I need an asym to compete. I know a guy who flew one on a 30 MK I. He welded a bracket forward of the stem, to fasten a tack line block, and had a sock instead of a furler. If I want to compete with this Ranger 28, I’ll have to add two furlers (one on the forestay and one for the asym) to be able to set sails as fast as him. So I can’t just shackle an asym tack line block to the spare headsail shackle on the stem, and hoist/douse the asym using a sock. I need a tack point forward of the stem to accommodate a furler. Thus my question to you listers: any experience with adding a bowsprit or bracket etc. to your C&C for tacking down an asymmetrical spinnaker? I did some reading last night on after-market bowsprits (e.g. Selden), but of course wanted to check with the collective wisdom on Stu’s list. Any advice or recommendations?
