That is quite a story. I bet the Valiant came out without a scratch right? The fates can be so cruel..
And the things I find in the lazarette--it never ceases to amaze me.. In there the hull-deck joint is visible in it's barest essentials. That is the flange from the hull, you were correct.
I'll be in touch when I am less exhausted. I took the opportunity to get an oscillating saw though, thanks for the tip. I'm thinking of removing some of the interior wood paneling below the stanchion so as to shore up the flange and stanchion base with fiberglass. Has anyone out there any experience with removing those wood slats?
