Locally we had a custom build of one of Ted Brewer's designs, around 38 feet IIRC, in aluminum. She was left bare and we used to joke that when the crew tossed their empty beer cans astern that she was 'spawning'..
Leaving the issue of such jetsam for the moment, it was a lovely vessel, and was especially nicely fitted out below. The cockpit and been painted in two part poly, but decks, cabin and topsides were left bare except for nonskid areas that were likely of Treadmaster type material.
She made a couple of voyages to Mexico and around the Pacific.. sadly the owner/builder has turned to power and now owns an American Tug. But I'm sure that Sandingo
is making some serious track still.
In 1986 I did my first 'offshore'/deepwater delivery from Victoria BC to California.. on a Colvin steel schooner.. it was not a terribly satisfactory trip for a number of reasons, however there was never any doubting the massive strength and integrity of the vessel.. no chainplate concerns, deck leaks, or any of that.
I still think, though, that given the opportunity I'd probably still go for a solid, rugged F/G boat like a Passport 40 for such a trip, but mostly because equally good metal versions of similar boats are quite rare in North America.
