I don't know if it was said already in this posting:
Take a shockcord with a hook, tie it at the center of the rear cross beam and hook it somewhere where you can easily reach it. If you want to heave to, take the hook and put it on one tiller. Now you can heave to and use your both hands all the time. I got this tip from Mary, it is one of the best one ever posted here.

Cheers,
