I've been waiting several days for the boat to lie in the right position so that I can get to the cover ties to fix this. Yesterday it was nearly reachable - without getting nig smothered in mud - perhaps today will be better, we'll see.
It was better.....I managed to retrieve the ropes, but could not reach far enough to fix them in their correct positions. Mike kindly offered to go out the next day when Mabel was floating and move the ropes along to their correct positions. All completed and shipshape! Thanks Mike!
