The wind picked up suddenly, and I had a wild ½-mile ride directly downwind back to home base. The daggerboard couldn't be moved up (I daren't move forward—nor secure the mainsheet), so just hoped for the best. There were times when the bow became partially buried in the "next" wave. Concerned, I watched as my paddle (mounted forward) broke up oncoming water, and watched as the mast split waves in half! My question: Has anyone actually come to a memorable "submarine stop" in a similar situation?
