Thanks for your reply. I am hoping for more detail from an email sent to Brewer’s Design company. I know I could take off a through hull and look into the hole at the material pattern, and same with a deck water or fuel fill port or air vent, but I’m not currently anywhere near the vessel and there is a limit to what a seller would allow at an early stage.
A survey would be a future step if a sales contract was obtained with contingency on the survey. I would see about locating a surveyor that would be willing to look a little deeper than typical.
