I'm new to the N20.

I want to know how much or how frequently people adjust the mast rotator from on the wire. I'm used to a single mast rotation limiter on the boom such as my Prindle 19 has. Has anyone re-rigged to a mast rotator system other than the dual outboard system on the N20?

Not all the time, but frequently enough to warrant it's existence.

the system works pretty well. Only issue is sometimes all the chaffing of the line going around the boom makes it difficult to pull in while under load.

But thats what the crew is for.

Ok, follow-up question. So how do you decide when to adjust the mast rotation when you're on the wire?

Its all part of the sail trim equation. The right mix of mainsheet, downhaul and rotation.

It depends on what the wind conditions are as to what you want to set your rotation to.

Please tell more, as I am new to the Inter 20 (strangely I have also come from a Prindle 19).

If you are buoy racing, you really only adjust it when you transition from upwind to downwind. Although our boats (Nacra 20 and Nacra F18) came factory rigged with the outboard rotator controls, we're going back to a boom system on the F18 for buoy racing. Usually the crew is inboard to hoist the spinnaker so the mast rotation, as long as it can easily and reliably be set during the transition, can be adjusted more quickly while they are inboard. We're rigging a 4:1 system inside the boom that has an indicator to show exactly where it is set (even if the sails aren't loaded up fully while turning downwind). It will take a little more practice to make certain it is set correctly, but it should work well.

On the Nacra 20, because the focus is distance racing, having the control outboard gives you a little more flexibility so it is staying outboard. It is being moved closer to the daggerboard so it can be accessed without having to go quite so far forward. Obviously it is important to get the mast rotation correct between upwind and downwind - it can be a bit of an adjustment while reaching and can be a good depowering tool when over powered (over rotating).
