roywmoss 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.)

Gary M 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.

Well...I can't argue against him, can I???? Neither can these here bellow.....

Jotun I am not a racer and am not overly concerned with performance. The sails that come with the boat are relatively new, so I have no plans to get others. It sounds like the full battens will do just fine for me. Sail trim? Who has time for sail trim? I've got two toddlers I'm usually chasing around.

Gary M I would hate to disagree with our esteemed friend from Portugal but I believe that there are performance benefits to full battens. Certainly they will last longer.
As I said above I am currently getting a new main for my S2 9.1 which I use almost exclusively for racing. My sailmaker had to talk me into it but then I have been buying sails and racing against him since the 70s.

P.S. Gui I am currently reading a very interesting book on Sir Francis Drake, apparently he had a few runs ins with some folks from over your way.

PBzeer As a collarary, I would offer PB's guide to sail trim. Epoxy the telltales straight, then you never need to adjust the sails. Those of you who find the constant tweak of sails in search of that elusive half knot to be sublime, just keep on keeping on.

Cruisingdad Well, for those of you reading, here are cruising dad's uneducated thoughts on which is better:

I would always get a fully battented and I would avoid inmast. You lose performance with the inmast - or so it seems to me. My old friend Giu (Whom I taught to sail, by the way on his training wheel) is probably the board leader on racing (thanks to my expertise). However, for those of you that are cruising, go get a full battented main as a nice compromise for those of us who do not know how (or don't care) to nit-pick the cloth. With most of our hull designs, it would not matter that much anyways.

I would agree that a non-fully battened sail, in the hands of someone that knows what they are doing, is going to give better performace. The question is: DO you really know what you are doing, or did you take CD's class on sailing: Raise your sails you go. Drop them you stop. Turn left. Turn right. Awesome!! Go grab me a beer and you graduate.

So Pilgrim, the question you have to ask yourself is: How ya gonna use that tub of yours? Cause CD, he's the one anchored out watching all you guys running around the beer cans while I am the one drinking out of em!!

My opinions....

PBzeer I'm with TB, I have full battens because tweaking sails is not my cup of tea. Get a good set, then get on with life.

Cruisingdad Tb, Giu,

Exactly!! That is why my Catalina with its inmast does not have them... so I can go faster and beat Giu! Isn't that right??
02-09-2007 11:14 AM
TrueBlue It's very rare to find full battens on racing sails, for the reasons Giu and Charlie pointed out.

The main on my ketch rig has them, due to the relatively short boom. I like them - mostly because I'm a lazy sailor.
