Actually no boom either, so pretty specific and since multihull I have a wide area to let it just lie flang dang on the trampoline. But when I start to motor toward the marina (always drop where there is sea room) it tries to fly about. I've been taking the time to gather it and bungie it together, but sometimes there is traffic and I'm not maneuvering with either sails or motor. Is there a better way? Suggestions welcome.
