Notes

WHITBY 45 MKII (1980+ only 2 or 3 built):
Draft was reduced to 6'. (cast lead keel made longer and thicker and swept-back rudder was redesigned to be more vertical.)
The deck was raised .16'. to increase headroom, the former low coachroof was extended for and aft, and the cockpit divider was eliminated.
The sail plan remained the same, but the interior was completely redesigned.
