A few answers
I too was a little concerned about keel bolts. Some corrosion but not enough to worry the surveyor. I was there for the survey - a must in my opinion, and formed an opinion that the surveyor knew his stuff pretty well so I ended up trusting his judgment. Once on the hard, no separation was found between the keel and the hull so now it is a matter of replacing the nuts and washers one at a time if I chose or just cleaning them up and coating them so they do not corrode further. We also tested the strength of things with a few grounding on the ICW as well. No worries.As the boat is an early epoxy boat, the core should not be an issue. As long as the core has not been exposed to moisture through some kind of damage, it should be fine. Overall, the build quality of the S2 35C is very impressive. Probably better than most new boats today. We have two doors that bind a bit. The worst one is the one into the head from the salon. The other is the one from the galley into the rear cabin. As they are all close fitting, oval doors, this slight binding didn't concern me. I believe it could be more from the settling of the cabinetry around the engine compartment rather than really a hull deformation. Even if it is deforming to some small extent, an 1/8 to 3/16" after twenty plus years of use may be more than acceptable. One other thing, the way the chain plates are installed, if the inner rods are not kept the right length, you can deform the deck. Sight along the bottom edge of the cabin side where it bends out to the flat deck area from inside and you may notice a raised area by the chain plates. Once you see it, you will notice a gap between the teak cabinetry and the fiberglass at the chain plates. This can be corrected by backing off the rigging and shorting the rods back up. I believe that this could also deform the deck enough to cause a door issue. I’m going to find out later this week when I re-tune my rig. I got to talk with the original owner of Fast Company. It won a decent number of races for him when it wasn't being the comfy cruiser his wife wanted. As he was a dealer for S2 as well, he also said that the 35C was the S2 owner's baby and he wanted it to be the best available. Both the deep and the shoal keels sail well and, as you might guess, the comfort level at the dock is great. It is a center cockpit though, so expect somewhat more rolling than the normal aft cockpit boats of this size. We also have noticed that it is more difficult to see around the Genoa, but easier coming into the dock. Everything is a trade off and, at least for us, this boat was the best compromise of price, value and performance we could find.
