Bartender 20.5

Designed by George Calkins

A newer addition to the Bartender line, drawn to fill the gap between the 19 and the 22 after a number of builders had stretched 19 footers on their own and liked the result. The 20.5 is 20 ft 6 in long with a 6 ft 10 in beam and more freeboard than the 19, enough to take a cuddy cabin comfortably, and she can be finished as an open runabout or with the cuddy.

She is the first of the small Bartenders really set up for inboard power: the plans show a four-cylinder installation of 75 to 140 hp, with a drawing worked around the Yanmar JH3 and JH4 diesels, while an outboard of 40 to 60 hp in a tilting well is the alternative. Built to the weights in the plans, the designers expect 2 to 3 gallons an hour at 15 to 18 knots. Like the rest of the range she is plywood over sawn frames, and the plans come for lofting or with full-size patterns, with an instruction book and materials list either way.
