Just got the chance to rigg a 2012 Gator 7.0 m2 sail. Luff = 463 cm; boom = 190 cm. When rigged on a Severne Enigma 460 cm SDM mast + 1 cm extension, it's a perfect low wind trim : nice belly below the boom, flat profile above the boom. With a +2 cm extension, it's a high wind trim with a flatter profile below the boom. Battens ends just above and below the boom's head cutout are rotating very easily and freely around the mast when the boom is set at 190 cm extension.

When viewed from the downhaul triple pulley, this is how the 3 bottom battens (#4, #5 and #6 from top to bottom) should look like with their end just kissing the mast from the side : https://fbcdn-sphotos-e-a.akamaihd.n...11465425_n.jpg

When viewed from the outhaul's end, this is how the sail's belly and the 3 bottom batten's end (#4, #5 and #6) should look like near the mast panel : https://fbcdn-sphotos-d-a.akamaihd.n...43724738_n.jpg

This is how the loose leech and flat bodied top half of the sail (batten #1, #2 and #3) should look like : https://fbcdn-sphotos-h-a.akamaihd.n...74123066_n.jpg

So, it sounds like you do not apply enough downhaul tension to your sail, even if your are spot on with the specs. I would suggest you try to downhaul a bit more your 2011 Gator 7.0 sail (Luff = 475 cm) : 460 cm mast + 17 cm extension. The batten just above the boom's head cutout should be freely moving just by hand. If you have to force more to rotate the batten's end by hand, try to downhaul more by adding +1 or +2 cm mast extension. However, make sure that batten above the boom still retains some curvy profile in the first third close to the mast panel. If that batten is straight flat close to the mast panel, either you have too much downhaul, too much outhaul, or both.

Cheers !
