      Although the Hunter 34's design is over 30 years old, it still has a modern look. The wide 11.58-foot beam and tall rig that towers more than 51 feet above the waterline give her speed in light air, but also contribute to her tippy tendencies. Courtesy of YachtWorld

Endeavour 32 Used Boat Review

August 13, 2025
The Endeavour 32 began life back in 1970 as the Irwin 32. Ted Irwin designed her as a dual-purpose cruiser-racer before the development of the IOR. By 1975, the IOR was in full swing, and boats such as the Irwin 32 were obsolete as racers, since PHRF had not yet emerged to help handicap non-competitive boats raced at the club level. Although the Irwin 32 and the Endeavour 32 look identical and have the same displacement, the Endeavour 32 is listed by the builder as being 4" wider, 4" longer overall, and 6" longer on the waterline.

Determining a Fuel-efficient Engine RPM

Determining a Fuel-efficient Engine RPM

My boat is a Hans Christian 41T, with a waterline length of 36 feet and a displacement of 38,000 pounds. The engine is a Volvo Penta TMD-30A rated at 90 horsepower. The prop is a Maxprop, three-blade, 20-inch prop with 12-inch pitch. A table illustrating speed at various RPMs shows that there is a linear increase of speed with RPM up to about 6 knots (2,600 RPM), but then the speed tapers off with increased RPM. Based on this, I presume that motoring at about 2,600 RPM is optimal fuel burn and speed. Is this correct?
