[quote=sierracat][quote=tiger2216]Pre 1990 (or so) Nacras had clew plates, after that they went to a clew traveler. This was a piece of Harken track with a traveler car and cleat. The traveler would allow for adjustment on the fly. As the wind picks up you want the sheeting point further forward to help flatten the sail. Downwind in light/medium air we used to release the clew traveler completely to give the sail some more shape.

Boomless rigs are not "lower performance". Nacra used them on all their boats until the Inter18 came out. The overall adjustment of the sail shape is more limited. The main disadvantage is the adjustment of the mast rotation. Upwind it is difficult to adjust to anything other than where it naturally wants to be. Also, moving the traveler has a more significant effect on the overall shape of the sail than on a boomed rig. For recreational sailing there is nothing better than not having a boom in the way and for racing its not an issue either.[/quote]
Thanks for specifics as to what was fitted on which era of boat. The hulls are late 70s I think, but I can't speak for mast and sail - they seem more modern. Not suggesting boomless is lower performance per se , someone else threw that out there, but I think they were just generalizing to help explain. Sail shape adjustment are something I haven't had to think about for a long time, thanks for the tips! Looking forward to a simpler rig and not hitting my head!<!-- editby --><em>Edited by sierracat on Nov 25, 2014 - 10:47 AM.</em><!-- end editby --> [/quote]
