Forestay tension with furler.

On my MKv I'm wondering how much forestay tension I need to put on the 155 furled genoa. I find is I put to much halyard tension the sail won't furl - so I'm assuming I need to tighten up the stay with the adjustment at the foot of the furler. Would this also have the benefit of lowering the foot of the sail closer to the deck?

Also, I have a 100% non-furling jib - I haven't used this yet. Is it OK to fly it hooked up to the deck shackle but without removing the furling drum? I want to be able to switch from the furling 155 to the 100 without assembling or taking apart the drum. I noticed there's a slight distortion with the drum at the tack but not too much.

Re: Forestay tension with furler.

Something for you to check - It is very common with C&Cs (it happens with my Mk III and with a friend's 34) for the jib halyard to want to twist with the furler at the top of the forestay, and after perhaps two turns, it becomes so tight as to stop the furling process. Usually you can over-tighten the halyard so the tension itself prevents the halyard from turning (be sure to ease off the halyard once the sail is furled, unless you want to store it over-tightened). The fix is relatively simple - you can procure a halyard guide from your rigger that will prevent the halyard from turning with the furler.

Re: Forestay tension with furler.

We used to have difficulties in furling until I added a strop between the head of the sail and the upper swivel. This raised the swivel to the top of the foil, so there was no length of halyard available to wrap and cause problems.

We normally release all the tension on the backstay before furling and ease the halyard.

Tightening the adjustment screw below the drum on your furler may get the sail a good sixteenth of an inch closer to the deck.

As to tacking your genoa to the deck without removing the drum -- if it seems to work, run with it. I'd be concerned, though, that the uneven strain on the luff would tend to pull the sail out of the luff groove. Your competition would find that more entertaining than you would.
