Howzit goin Tony?
The Round the World Volvo race is over. They did a film recap of those rockets leaving wakes with rooster tails, decks awash with green water, and white guys bundled up like penguins in goretex. I figure a hydrodynamic windscreen is the way to go. Hey, as long as coamers are coming aboard from the front!
Those scuppers are really pieces cut from a 1/4" xmatt layup around a wood form wrapped in mylar, like a strudel. Then the molded toe rail is sawzalled where you think they should be, the pieces (breadsliced at a slant for a yotsey look) laid in place, glued in, and then trimmed down to the profile of the rail. With some backup matt underneath they should work in a toerail that has not been filled in like 338. I glued them in as if the deck was there. That is the thickness of the slices was left above deck level so that water CANNOT drip down the openings onto the topsides. Dribbles should be taken care by the factory deck scupper.
In laying out the interior, you're correct, it IS with singlehanding in the forefront - but forever hopeful the double bunk convertable will get thoroly exercised.
