Notes

The Doug Peterson 1/2 Ton prototype "North Star" was winner of the 1974 Half Ton Worlds, in La Rochelle France. The Chaser 29 production model "Foxy Lady" won the Worlds the following year in Chicago IL. Bayliner bought the tooling at auction, where, with a different deck and coachroof, it became the BUCCANEER 295. These were unauthorized copies, never approved by the designer, Doug Peterson.
Disp. above is from SEAHORSE Mag, 1976 and believed to be more accurate than the the original displacement listed of 7200 lbs.
Thank you to Roy Cundiff and Paul Bishop for their input, corrections and additional information.
