The classic tramp is very soft, and I was unable to make it stay tight enough to keep the hulls tight on the crossbars through an afternoons sailing. I just finished replacing it with a black mesh lace-up tramp, and even before tightening the laces, it was tighter than the classic. My sense is that this will increase the responsiveness of the hull, and make it feel more secure underfoot. Can't wait to try it out!
