I have not found any structural repairs necessary over the 8+ years I have had the boat (other than racer/skipper inflected).
The boat has a few gel cracks at the cockpit seat to bulkhed area. The main chainplates at the mast come through the deck and bolt to a marine ply bulkhead. These need to be maintained, tighten and checked or they will work. I keep the mast pretty taut and main shrouds with a good pre-bend. Any mast play,bounce, could aggrevate this support connection.
I sail out of Denver and travel 1,000+ miles to 8 regattas a year in Colo, Wyo and Neb. Alot of
rigging and tuning. The air is a little tiner at 5200'' to 10,000'' elevation, which mean I can carry the 155% up to about 16-18 knots at times.
