Notes

Hull design began as the CHASER 29, a production IOR 1/2 racer designed by Doug Peterson and first built in 1975. Bayliner/US Yachts used a completely different deck and a number of other changes. Molds for this version were later sold to Pearson Yachts where, with still more alterations, it became the TRITON 27.
Shoal draft version: 3.5’/1.07m.
Thanks to Bruce Schaffer for providing updated information on this yacht.
