Andrew is building a Bermudan sloop and Ken is building the Bermudian ketch.
These are the rig choices currently available.
Oyster, the cabin is all V berth, with a center notch of course. The berth is 6' 9" long, so plenty of room. Also the centerboard case is offset to port (about 8"), so the interior is free from case obstructions, as it hides under the V berth.
This is the V berth top and the long rectangle (darker gray), is the centerboard case access panel.
