Good point. If we go through the trouble of repainting her, it would be nice to get her raised up long enough to clean off the dirt and paint the underside. Temporarily floating the boat may be easier on the hull than using a crain - and a lot cheaper. We would need a diver to do the inspection, obviously. If it's too rusted out, we'll obviosuly need a plan B.
Keep in mind that it's a double hull construction, too. If the outer hull is rusted, the inner hull still may be in good shape and may be usuable as a support structure.
Also, the vets and others are insisting that they want the boat to be sand-blasted, as opposed to the original plan of sealing the old paint and putting on a fresh coat of new paint. I think Rick said it was about $100 to dispose of one 55 gallon drum of contaminated sand.
