Notes

S&S design #1999.
After Yankee Yachts went out of business in 1975, a few boats were built by Heritage Boat Works (OR) and Vashon Island Boat Works (WA),USA.
From this latter builder also came the VASHON ISLAND 30 or VASHON 30, a Pilot House cruiser that appears to share the same hull.

The MK I, II, and III, were differentiated primarily by incrementally taller rigs as well as a few details in the interior layout.
(Hulls after #98 are designated MK II).
The MK III, has an additional 1000 lbs. of internal ballast. (Rig dimension as well as other details are not always consistent within a particular version.)

Available engines:
Universal Atomic 4 (gas)
Albin 2-cyl Diesel
Bukh 2-cyl Diesel

The S&S 30, built by Swarbrick Brothers of Australia is based on the same design (S&S No. 1999-C1).
