Here's where I am so far (an IFRIC, that's Intermediate Frame in Cellar, photo perhaps) on a Ravenswood. Should start doing the real lashings soon. Seems like a good time to think about ordering fabric, but how much Fabric? I'm sure it's discussed somewhere here and I recall seeing something about getting a length a foot longer than the boat. Is that a good recommendation? If so it would seem that, rounding up, 17 feet should do for the R'wood.
