Maybe you would get more responses if you post this on the Hobie 16 forum, as well. I know the Hobie 16 does not point as well as boats with boards, so it is going to be more than a 90-degree angle when you tack to go to the mark.

I also know that you are not going to learn much if you are using a compass for closed-course racing. Get the thing off your boat and watch what the other boats are doing.

Where do you sail?
