Captain John's Skipper Tips - 9 years ago

Tony, you can still have leech telltales installed on a furling mainsail (or do this yourself). You will not have any roach or battens, so the leech will be straighter. Attach telltales to the edge of the leech. Measure the distance from clew to head. Divide by 4. This will give you three "stations" to attach your leech telltales. For example, if your leech measures 28 feet, you would mark three stations spaced 7 feet apart. Try ribbon or yarn. Yarn might last longer. You can experiment with the number of telltale stations, but I would try three stations and see how this works for sail trim. You can always change this later. I am not very familiar with in the mast furling mains, but I've read that they are easier to stall (cupped leech from too much tension). You might want to sail with a bit more twist, in particular in light air. You want to keep the leech a bit flatter to help the delicate air exit off the leech without a lot of turbulence. Each time you trim, check your speed indicator. It will help you fine tune your sail trim. Let me know how this works for you.
