Sounds fair to me. Basically, you guys overstood the weather mark on starboard, a port tacker could tack inside you and still lay the mark and you'd be following them in all the way. You wanted to dive down to 1) get the other boat to tack earlier (thinking they were already on the lay line) and 2) build up speed to drive over them before they came out of their tack. Sounds ok to me, in the instance that you had already overstood the mark. Next time, don't overstand and make him duck you before he tacks .
