Mike,
I have footstraps both behind the rear cross bar and about 3 inches forward of the stern. I have big feet (12.5) and I can still steer the boat. Both straps are Dakine and mounted with through bolts and ss washers inside the hull.
You will also need an adjustable trapeze line for you and your crew to really use them effectively (especially the one''s farthest back). I also suggest a chicken line. You rarely use the footstraps farthest back unless the wind is really honking and the wave state is such--both times I have used these, I have also wished I had my chicken line engaged as both times we stuffed hard and went flying. The I20 can do some wild pitch poles with the chute up in big waves.
The self tacking jib is awsome--really great for novice crews who have their hands full with the chute alone in gybes. They help with fast tacks and gybes too. Wife loves it too--thinks its the greatest thing since sliced bread (no effort for the crew when we sail for fun :-))
Other suggestions:
1)cascading downhaul to make playing the downhaul easy--if you mostly sail with male crews it probably doesn't help that much.
2)Separate bungies for each trap line with enough tether to allow you to go forward without snapping (helps alot if you break one as your other trap does not fly away in big winds. Got this off of one of the Worrell posts--works great.
3) I'm thinking of changing the mast rotator to cleat closer to the shrouds so its easier to access by you and your crew in heavy air. Seen this on a few worrell boats--sounds like a good idea. I never liked the one all the way forward.
Hope this helps.
