Operational history

In a 2010 review Steve Henkel wrote, "the Jeanneau Eolia 25 was available either as a fin keeler (fixed draft 4' 9", shown here) or as a keel-centerboarder (draft 2' 7" board up, or 5' 11" board down). Although an outboard was an option, a high percentage of the boats sold have a raw-water-cooled Yanmar 1GM1O diesel of 7.5 hp. Either choice should power the Eolia 25 at hull speed. Best features: We think the layout is quite clever, with a double berth aft under the cockpit, an enclosed stand-up head in the highest location in the cabin, a modest-sized but practical nav station, and a U-shaped dining area seating up to 7 of 8 souls for that relaxing after-the-race beverage. The table slides down on the mast compression strut to form the center portion of a double berth, The arrangement below makes the cabin seem quite airy and pleas- ant, despite a too-small forward hatch and no opening ports, Worst features: We can't imagine why this boat has a PHRF rating 30 to 40 seconds a mile higher than her comp titor. We don't think she deserves such harsh treatment."
