I picked up a 76 Sunfish today and the hull is a light blue, at first, I thought it was painted but the owner said it was original gel coat. The hull is waterlogged, not sure of the weight but by the look on my wife's face it was heavy, me, I pick thing up and put them down! It had a lot of dark blue spots on it, at first, I wasn't sure what they were, then the owner said that they were Gorilla tape, whenever he hit something or he thought it was a bad spot he'd tape it then paint it blue, jeeze. The highlight was when he pulled out the other parts, all new, mast, spars, sail, daggerboard and rudder and tiller, said he had only used them twice. The blue hull with white deck and blue and red stripes was a pretty nice-looking boat, hope I can keep her original, depends on what's under the tape. I'll get some pics up soon.
