As with a lot of cored boats prior to SCRIMP, there are some boats that have core issues. A few with serious issues, some with minor and a lot with no issues. A lot depends on how well the boat has been taken care of. Were chainplates maintained, port lights sealed, leaks taken care of properly etc.? The one bad spot that must be looked at is around the exhaust. Many boats have no issue here but others are in tough shape but all are repairable.
