Hi all, I thought I'd post in this thread vs. starting a new one. In my cored-hull Sisu 22, I last year had a survey that showed the hull sound. It was previously and in-water boat, but it has been on a trailer for about six months and is only in the water for the day when it is used (2-3- times per month out here in CA).
Upon one recent haul out, the boat yard crew didn't line up my trailer perfectly and one of the rollers was out of alignment, causing a bolt to puncture the outer layer of the hull and expose the balsa core. Total size of the hole is maybe 3/8". Since then the boat has spent maybe 12 hours in the water, total.
We don't deal with freezing here, but I'm wondering what steps I should take from this point - just patch from the outside with a dab or 3M 5200 or West System epoxy? Is there some kind of moisture reading that I can have the boatyard undertake to see how much core got wet?
We don't have freezing here and again the boat lives most of it's life on a trailer, but I respect the danger that any exposure to water can mean for balsa coring.
