Re: International 210?
Rebuilt a 210 in Hawaii many many years ago. Actually we salvaged a keel and hardware from one that was sunk to put on the boat we were rebuilding as ours had been dropped on its keel and the keel had broken. The chief structural issue was that some of the bent frames had broken in the area of the mast step and cockpit. These were easily replaced with sawn frames. The Hawaian boats were all glassed over the plywood because of the prevelence of teredo navalis. Loved it as a daysailor, surfing off of diamond head. The blade job is a good idea as the boats simple winches were somewhat under powered for racing. And lifting the boom would be good: we broke ours at the gooseneck surfing off diamond head.... Boom was hitting the wave in front of us. Up our way not long ago someone single handed cruised their 210 down most of the coast.
