Crack worries
Scott:This a great boat (I have had an '84 for just under a year) and it is common to find some gelcoat cracking at stress points. Your post doesn't make clear whether the cracks are on the rudder or on the transom where the rudder is attached to the hull.I reinforced my outboard mount this past spring and learned that the transom is cored with plywood which is quite thick. If the cracks are on the transom, and unless there has been moisture accumulation and rot at this point, I wouldn't worry about it. Get a surveyor to look at it, and make sure the gudgeons for the rudder are properly bedded (with 3M 4200 or the equivalent silkaflex product) and tightened.If everything else checks out, you will be pleasantly surprised at the combination of speed, strength, and liveability which was designed into these boats. The cast iron keel requires a little extra maintenance and vigilance every haulout, and she requires a reef at 15 knots, but this boat is otherwise a low maintenance machine with a high fun factor.Good luck to you and keep us posted on the outcome.
