I think a crane could also put her back in the water pretty easily.
IN the old days, with a boat blown 300 feet onto mud flats, we laid down two tracks of heavy boards, tipped the boat onto a crude skid, ladeled greasy wet mud onto the boards, and about ten guys pushed and dragged her all that way. I was nine, but I think they also rigged up a block and tackle on an anchor. It was all very festive, even though the banks of the Rahway River (N.J., spur of New York Harbor) were evil-smelling muck.
It seems, looking back, that adults could get a dozen people to help them do anything in those days. Manpower was an easy answer. Maybe there were just more...men?
Then "East Wind", a former oyster dredger, promptly sank.
So my father got another bunch of guys to refloat her with gasoline pumps and 50-gallon drums. It was winter, and they drank scotch out of the bottle, passing it around.
All of it, for me, was way better than going to school.
Perhaps you'll remember this project that way some day.
