Sailmaker's Advice
Almost exactly a year ago I bought a new loose-footed main (along with a new genoa from the same company). The sailmaker's comments were that foot design was an individual's preference, and that he liked a shelf foot for ease of flaking and because it didn't drip rainwater along its entire length. However, I decided to go with the loose foot, somewhat out of curiosity, and to see if the trimming advantages really existed. After a year of racing and cruising with the sail, I am very happy I made that decision - it is much easier to trim. Indeed, it does not flake as easily as my old main, but that is a small price to pay. I roll it and stow it below anyway, so that is not an issue for me. And Mike makes a good point: if you have mid-boom sheeting, there is a lot of stress on the boom at that point, as most of the wind's force on the sail passes through the clew slug. But from now on, any main I buy will be loose-footed.
