Couple quick questions, the center boards are made of metal...is this factory or did someone make up a set of their own. How is the mast base/bottom of the mast supposed to look, am I missing something? I do have a big bag of parts that I havent rummaged through yet that it could be in (mast base)
It would also appear that at some point someone tried to add a crossbar to the front of the boat (like the newer ones) we plan to seperate the deck and hulls to make some repairs, should I bother reinstalling it, or perhaps buy the parts from IFG to update it properly...
At one time, Isotopes had metal (aluminum, I think) centerboards. Frank tells stories about how they used to hum, and you could tell if someone was gaining on you because their's had a higher pitch.
The mast base looks fine to me.
The crack in the picture looks like a straightforward repair. I'd hesitate to separate the deck from the hulls - what makes you contemplate that? The compression bar is not the current design, but it might have been made that way. I do notice that the bridle wires are not attached. Does this boat have a roller-furling jib? The trampoline looks new (it's a recent style anyway), although it is not tied to the front crossarm. There should be a rod across the front that you lace to. One thing to check on Isotopes of this age, is for stress-cracks in the crossarms. The front crossarm, especially - where the dolphin striker is welded on (newer ones are bolted), can fracture over time. The mast looks like it might be newer than the hulls. At least, it doesn't appear to have diamond wires (which is good). Sail number 1100 is Howard Alexander's. He might know something about the history of the boat. Howard or Frank would be good people to check with about what it might need and how to fix it up.
Otherwise, if you bring it to the lake, we'd be happy to look the boat over for you.

Eric
