Great Dave - - I'll put you on my short-list for the day that I'm ready to sell mine (grin).
I recall, I think, that Derald told me "about 40" or something like that, but he wasn't into bragging so we didn't focus on that so much. Andy Hutchison may have a rough idea how many boats Derald built. And by the way, Andy's boats are just as awesome, in my mind.
I feel fortunate to have had 3 of Derald's boats, a very early one, a brand new Harvey boat that I broke my arm in and damaged on the rocks at Big Drop III (Derald did the repairs shortly before he passed, and the boat now lives in Port Angeles, WA), and and the modified Briggs 16' with a transom that I have now. I miss the Harvey, but the Briggs is more of a workhorse and great big water boat.
