After 4 1/2 years of ownership, I'm still working and improving my 53 Classic.
Over that time I've redone the bottom with a complete blister repair and water barrier job; complete galley remodel with all new appliances, flooring, countertops, lighting, etc., and a starboard engine out of frame rebuild. Of course, the usual soft goods too; carpeting, drapes, bedspreads, saloon furniture, etc. New electronics...new icemaker on aft deck, new window glass on aft deck, rebuilt stabilizer system....repacked shafts and bearings, props re-balanced, serviced the windless, and certified the fire extinguisher system.
And oh yeah, lots of varnish work too. The next owner will get a very nice boat with most of the work done for him.
