Along the foot of my main sail, i have a pronounced "bag" (sail not stretched properly. My outhaul is stretched to the max, the sail is atop the mast, and the cunningham is tightened.

Is it time for a new sail? Am I getting optimal performance running like this? I have also noticed some sails which are not secured along the boom track. Can I remove mine from this track? If so must I also remove the protecting layer running along the foot of the sail?

Thanks

Frank: Your sail may be cut with a "shelf" at the foot--intended to maintain the airfoil shape close to the boom, instead of making it board-flat down there. You get the same effect from a loose-footed main (attached only at the tack and the clew). Have a sailmaker look at it--it may be a tired sail, or it may be the design. If you go loose-footed, you may get approximately the same shape, although it'll be adjustable for wind speeds (looser/fuller in light wind).

Some folks pay lots of money for custom racing sails with that 'shelf'. ;>)

If it's a 'stock' sail and has a big 'shelf' it's probably blown out. If not a stocker, that bag may be there 'by design'.

Frank, my 1985 TR mainsail had a pronounced shelf at the foot when I acquired it. It was pretty blown out from use. To save money, I took it to a local sailmaker who recut the foot of the sail, and extended the life of the sail by several years. I think it cost about $ 150, which is a whole lot less than a new sail. I agree with Dave: take it to a sailmaker for evaluation and suggestions.

Its hard for a sail maker to tell you whats wrong by just taking the sail in. Take pictures of it when its up and on the boat. It will help the loft alot.
