A completely new design from the the earlier RANGER 26, but also by Mull.
Thanks to Daniel Marks, a former Jensen Marine employee, for providing original brochure and updated information.
It’s thought that very few of this model were built.

Like the earlier DEHLER/DEHLYA 22, intended as a trailer sailor, with a drop keel (375 kg.), additional water ballast and retractable cassette type rudder arrangement. (Though a fixed keel version was also available.)
Thanks to DEHLER 25 owner Philip from Sweden for providing corrections and additional details.
Also called DEHLYA 25.
Diesel inboard available as an option.

Later it became the TRITON 21.

S2 6.9 GRAND SLAM.
The same hull as the S2 6.7 (designed by S2 in-house designer Don Wennersten), with changes to the cabin, cockpit, and sailplan overseen by G&S.

Thanks to Bob Proctor for providing updated information for this yacht.
A few boats were turned out with a fixed keel.(draft: 4.5′)

The IRWIN MINI-TON (<16.5' IOR) is thought to be similar to the IRWIN FREE SPIRIT.
