Thanks Gui, nice shots and I know. When he was talking me into full battens I checked on the Net and found very few boats with them.

I may have previously stated what he said poorly. I believe he said that full battens can be as fast but that the competitive sail life will be longer.

It is an experiment so I will let you know about September what I think. I am a bit nervous about it but we will see.

Assuming sail dimensions do not require full battens (see Guiletta post), from a cruising perspective the principal advantage of full battens is:

1. Sail does not flog, therefore is less noisy and easier to handle, especially reefing and dousing. Excellent when combined with dutchman flaking system.

Principal disadvantages are:

1. Sail does not flog, therefore does not depower as efficiently, increasing risk of broaching, etc.

2. Compression from batten to mast increases friction, in larger boats requiring special fittings/cars to reduce friction and allow battens to articulate when sail is flaked.

3. Greater chafe damage potential on (the longer) batten pockets.

4. Increase weight aloft.

5. Increase initial cost, possibly offset by longer sail life, itself partially offset by higher periodic maintenance.

Alternative is compromise of some full, some partial. Example is "2 + 2" (top 2 full, bottom 2 partial.)
