The Mark 3 interior was designed by Phil Morrison in 2006 for GRP construction. This design has no stowage compartments (but may have stowage options, such as bins, in the stowage bulkhead), no drip rail, wrap over gunwales, no stem post or shroud blocks, dished fore and aft decks, raised area on foredeck for mast step.
Transom scuppers can be ordered if required, but the decks dish towards the cockpit, rendering scuppers ineffective.
