[quote=P.M.]There has been a lot of mis-information the last couple of weeks regarding boomless rigs.  Simplified illustration, boomless rotators "induce" rotation, while boomed rigs "limit" rotation.  A lot of people just don't get that.  The simplicity is the beauty of boomless rigs.  As you apply mainsheet, mast rotation actively decreases and draft is reduced, and the opposite happens when you ease the sheet.  Boomless rotation controls aren't really necessary upwind.  Down wind they will make a difference in a performance tuned rig.

Clew plates and clew tracks:  There is a wide range of clew tacks provide on the sail, these adjustments are provide for the infinite ways to "rake" the rig.  Once you're set up, adjustments should be no more than a hole forward or aft. With the clew traveler it's only an inch or so, once you find the sweet spot. Rarely do you need to adjust this.

Leebow, not much is going to change for you relating to draft in your dacron sails, they are tired.  They get full and no level of sail controls will fix it.  If you chose to add the rotation arm, you should get the oversized wide arm.  It will make using the arm as a limiter manageable, and it adds performance down wind.  I think I have some rotation arms I could provide, I'll have to check.

Here are some pics of the oversized rotator properly set up with rotation cleats.

Disclaimer: I actually have a lot of experience with boomless rigs. Third pic is provide to show how flat you can tune the sail without using a rotation limiter.
