We can enlarge the tail of your boom (every boom on the market) so that the sail does not deform its profile on boom's tube when you go downwind. See the picture here under.

Different widths are available depending on sail size and, as it is custom handmade, on your request. We also do lots of parts to fine tune your boom, like reinforcement, adding pulleys, etc.
Contact us to get a good offer.
