If (when) the wind comes up and it’s time to douse, you’re going to want to hoist your genoa so you can douse the spin behind it. Chafe and twisting aren’t going to be your friends. I’d much rather have the asym flying from a halyard that’s above the genoa halyard. You shouldn’t need anything as heavy or bulky as 5/8” Sta-set for light air spin sheets. You might think about using a cored line (maybe with the front part of the cover removed) for sheets and using soft shackles to attach them to reduce weight on the clew. An asym for a 30’ boat doesn’t generate very much load in winds under 10 kts if you’re sailing true wind angles greater than about 130, so you’re going to be more concerned about having a line big enough to hold comfortably in your hand while trimming rather than one with sufficient working load. I’ve forgotten the actual dimension, but I think the light air sheets on our 36-foot C&C 110 are something like 5/16-3/8.

If you aren't gybing your asym too much I would not be too worried about using your spare jib halyard, but it will chafe more, and you need to ensure they aren't twisted at hoist or douse. Outside the forestay gybes should not be a problem in your light wind scenario but you should try to hoist and douse on the same side.

The boat came with two halyards forward of the mast, both in good condition. I use one for the genoa (on a furler) and plan to use the second one for the asym. I believe I have no choice but use the asym as a genoa and gybe between forestay and mast. By looking at the rigs on sailboatdata.com<http://sailboatdata.com>, it seems to me that both the 39 and the 35-3 also have a similar setup (all sheaves below the forestay). The reason I mention the use in light air was that I was concerned about the weight of the sheets. I'm currently using 5/8 sta-set as genoa sheets and although they are nice in the hand they really pull down on the sail when broad reaching in light air. I'm not looking for sheets that are under-specced but might be willing to pay a bit more to get a lighter sheet. Just for reference, the document I'm mentioning is here: http://www.cncphotoalbum.com/doityourself/spinnaker/spinnaker.htm cheers, Sébastien Lemieux Merlot X - C&C 30 mk2 1987 Lake Champlain On 2013-08-13, at 14:24 , Joel Aronson <joel.aron...@gmail.com<mailto:joel.aron...@gmail.com>> wrote: I agree with Bill about the halyard and blocks. 70 feet of 5/16 is plenty. You can use Sta-Set and spend the rest on a new halyard. I flew my asym wing and wing last week in light air. Boat speed went from 2.3 knots to 3.3 knots after I gybed the main!

We always jibe ours out and around the headstay, inverting it. Usually they are on a pennant, a few feet off the tack. If you have an anchor roller that is substantial, it is best to get them away from the forestay, but of course only if you have it on a spinnaker halyard above everything, not on genny halyards. And yes, you need snatch blocks on the toe rail just like a regular spinnaker. Famous Last Words: "Will only Use this sail in light air" Always have an exit plan for heavy air!

I've read through the DIY document on the photo album site and from this I assume that I will need to use it from an genoa halyard (both sheaves exit just slightly under the forestay). I've got a few questions left: The manual of the 30mk2 specifies 70' sheets for a symmetrical spi, should I go with the same length for an asym? What should be the length of the line pulling the tack (what is the name of that line?)? I will use this sail only in light wind, what type of rope would you recommend for the sheets and tack line? I'd like to try a single braid for that purpose, anyone has experience with the Control DPX from Samson (in 5/16, $1.44/ft at APS, 2.9 lbs/100ft). The halyard is already in place. Also, am I correct that I will need to shackle a turning block on each of the aluminum piece at the end of the rail in order to lead the sheets fairly to the winch?
