An updated version introduced in 1984 moved the traveler to the cabin trunk and added a chart table. Reported displacement increased to 10,400 lbs.
Beginning in 1985, the Yanmar 2GM20F, with 16hp, was installed.
Earliest hulls had balsa core in their bottom and in the horizontal areas of the deck. At some point, hulls became solid layup.
