Composite Yacht is a friendly family run boat builder in Trappe MD.
They do indeed have a 8 x 48 ft table that could also be re-arranged to be 12 ft wide (but shorter, unless they make a few more slabs). they also have a shallow cylinder section table to make the gentle curve for hard cabin tops. They are familiar with all the flat panel construction techniques such as rebates and deck edge radius .
