I dunno, I think a foam cored hull is not designed or built to last 37 years. Especially one that has been raced hard offshore.
Well, years ago I asked John McConaghy and (I think) the Ulrechts who built Brinders how foam/carbon boats were doing. They both said that they had basically an infinite life span unless accidents occurred. At that stage the early ones were only 18 years old or so but some of them had already done lots of miles on the ocean and on shipping cradles, like Sagacious V. Macca said that he had been asked to go through her after her second trip to the northern hemisphere. He found a coin-sized patch each side near the mast that needed a touch so he mixed epoxy in a syringe and fixed it there and then.
Foam sandwich boats have been around since the ‘50s. Boomerang VII, the first big foam boat in Australia, survived 50 plus years including a bunch of Hobarts so how did she survive over 37 years, especially since cores, laminates and resins were so crude then? Even on of my Lasers is now about fifty years old and I don’t think it has any issues.
So what foam sandwich boats are having problems? What are the corresponding single-skin boats doing? What is the fatigue like when bending forces in a skinny single skin hull put the compression loads so close to the tension loads?
