Faster,
Sails are not brand new but I had the genoa into the sailmaker last month for some repairs and the sailmaker said that the sail is nowhere near replacament time. Sets well with little bagging. I'll certainly be looking into the Campbell Prop. that has appeal for sure. You use a two or three blade ? Previous owner of the old dear (she'll actually have a real name next week, yeehah !!) changed from two to three blade a few years back and I do wonder whether a two blade would be better. Less drag maybe ? Need to do a bit of propellor homework.
Thanks for your input
Andrew

Answered my own question. Campbell is always three blade and three bladed props have less vibration problems.

labatt will become famous soon enough
I sailed on a couple of boats this summer with two foresails on separate furlers. They both had 135% or 150% genny's with a 100% jib as the second sail. We'd start with the 135 (or 150) in the morning, and then as the wind picked up, we'd move the 100. The nice thing was that we were able to maintain a quality sailshape on the 100 as we reefed it down, vs. a crappy sail shape on the 150 once it got to around 110 or so (even with moving the leads). We had one set of tracks and swapped the sheets when changing which headsail we were using. If you've got the money, it made life really really nice.

Can you get a 150% genoa with a wire luff? Then you could fly it like a cruising genneker. When you are done with it, drop it and stow it. No hanks

Actually they are available in 2 or 3 blades from 10" diameter up. True, the 3 blade (which we used, switching from a floppy worn out 2 blade folder) minimizes vibration issues. We noticed a slight drop in sailing performance compared to the folder, but, under power, forever rid ourselves of marginal reverse performance, vibration, and the occasional hassle of having only one blade open up - that's just scary.

In any event we were happy with the change, especially given we were no longer racing that particular boat.

I don't see why you couldn't get one with a wire luff...if you're paying for the sail, they should be able to accomodate you.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Sounds like a pretty good idea in that in drifting conditions the wire luff is acting as a removeable forestay which doesn't need to be set up with a lot of tension. Only negative I can think of is that the wire luff would be a bugger of a thing to stow. The idea , which is essentially a cruising shute cut more like a genoa does seem to have merit. I'll have a chat to my sailmaker, see what he thinks. Stay tuned.

I see your point on stowing the wire luff. I can't wait to hear what your sailmaker suggests. Yeah, you guys are right, we need a pointing genneker!
