Guys - thanks for knocking some sense into me re sail selection. Here's where I'm at now. What do you think? (The roller furler has to stay)

New Sails - both declarable for racing.

155% RF genoa, 230 sq ft. Triradial PE 15 Pentex (film/scrim/film)
No accomodations made for reefing. Full skirt.

100% RF jib, 4.4oz dacron. cross cut.

Make more sense to the crew?

4.4 seems a little light for my sailing area. Have you talked to Point sails? They are very good with pentex.

I agree with Frank. For a 100% which (presumably) you are running in winds of 15k - 18k+, 5.5 or even 6 oz would make more sense.

Haven't spoken to Point. Where/who are they? Do you have contact information for them?

Curious... question for you RF guys who race.

What are the 'effective' ranges for roller furling jibs in 'competitive' situations?

Ehat will a 155 furl down to before you fall off the edge of performance?
Ditto for 135?

First off - guys, I agree, 4.4 is too light, meant 5.4. Will consider going heavier per your suggestions.

About furling -

My experience is that with the 135% Bi-radial sail I have now I can can reef down to ~120% with no major loss of pointing ability. That's a dacron, Catalina loft sail, with foam luff pad. I think that may say as much about the sails ability to point un-reefed as it says about anything else. Beyond ~120%, pointing is compromised but to reef that far I would have to be so powered up that I'm moving pretty well.

With the current inventory, I set the sails like this, assuming I want to sail fast, either racing or daysailing - Up to the high teens or maybe 20 knots, I fly full 135% and full main. Nearing 20, the vang would be on hard and I would be "vang sheeting." I'm dumping the main in the puffs and the sail is going out but not up b/c of the vang. I have a very thin mainsheet - 5/16, I think - on a 4:1 tackle. The result is instant dump when I trip the cleat.

Over 20, I reef the main to the first reef.

If the wind comes up a bit more, I put two - three turns on the roller furler - which gets me down to maybe 120%. At that point I don't notice a lot of change in pointing from 135 and 1 reef in the main. (I do notice a reduction in pointing when I reef the main, btw)

With the new sail, I don't expect to be able to reef effectively, hence the working jib.

Justin,

Do you plan to keep your furling 135 when you upgrade?

If not, I would be interested in buying it. Hey Jude finds that my 150 is always too much for most of the day on SF Bay.
