We'll be looking forward to Dr. Judy'a response. I think the draft is still deep compared to the sail pic she sent as an example . Yet, I've sailed in PHRF races on a club level with worse mainsails.
I am very much looking forward to your analysis DrJudyB!I’ll measure the camber and twist later today, folks. As Said before, it loooks serviceable, but looks overly full. But the numbers will tell.
But in the meantime, I wonder why several people have recommended the OP tighten the Vang. On a dinghy, tightening the Vang bends the mast which flattens the sail. But on a bigger mast, the only thing the Vang does is tighten the leach, which reduces twist (increases the angle of attack at the top,)
I agree that it's worth experimenting with increasing the batten tension, but it's not clear to me that increasing batten tension will be an overall improvement in this dacron sail. Increased batten tension might not get rid of the vertical wrinkles, the way it would with a laminate sail. It might just make the draft deeper and rounder in the leech section. It's worth experimenting, but it might not actually sail better.Looks like you need a little more tension on the bottom batten. I can't see how it is adjusted. Multihulls, in part because they carry a lot of roach, nearly always have batten tension adjustments (even Hobie cats).
Looking at the picture more closely, it looks like the line goes through the grommet and down along the leach on the other side. Similarly on the two grommets above, which seem to be connected by the line running between them. So, a furling system and/or a reefing system.Doesn’t seem to be a reefing line as I can’t see anything on the other side.
The Dutchman system has two lines that thread through the sail. In my case the line is 400lb fishing line. The system works very well.So, some observations. What is that large line on the right hand side? Doesn’t seem to be a reefing line as I can’t see anything on the other side. It's nice that the sail is back lit so you can see through it. So, with that line and the smaller lines going up presumably from the dutchman system, the sail does not seem to be free from encumbrances of reefing and furling. Lines seem to be tight...But I’m not admittedly familiar with the Dutchman system...
