I'm finding the clew of my new slalom sails and the back of the boom are dragging in and out the water while sailing along. I tried heightening my boom but that doesn't work. I've changed harness line lengths to 24's, used to use 22's but my supplier doesn't manufacture 22's. Didn't have the issue with the 22's. I'm 5'6 ft and 65 kg. Any idea's how to rectify this issue?

Or move the mast base thing back.

Ive had the same problem with one of my 8.6s, my older one had no probs though. More of an issue in the larger chop/open water. My solution was to add an extra 2-4 cm on the mast extension but not down hauling all the way to that extra length, so your sail is sitting 2-4cm higher up than before. When you consider the boards with the dipped/hollowed out area around the mast track the sail could be that bit closer to the water to be annoying. Works for me.

Thanks for all the tips, I'll give it all a go.

Buy a foil, should lift you high enough to stop your sail from dragging in the water.
Its the new future of windsailing.

Pfffft !
Its just a fad, like foil skiing

( that's a four mojee thingy )

No the Overdrives are still basically the same, I reckon less downhaul than recommended might do the trick, then I'll try all of the above suggestions. When I downhaul to the recommended setting, it's pretty floppy, probably perfect when your really powered up but I probably don't need to downhaul it to that setting all the time. I must say that the other day when it was happening I was a little underpowered on and off. Will keep you posted on the experiments..

Ok. Today I gave the sail less downhaul, problem rectified
