Mamba 29
Description
The Mamba 29 is a Swedish fractional sloop cruiser-racer designed by Jan & Harry Becker and built by Mamba Boats (Sweden) from 1980 to 1989. It's a compact, fast, and affordable family cruiser with a modern hull shape (fin keel with spade rudder for good upwind performance and handling), a fractional rig for easier tacking and better balance, and a spacious interior for its length (sleeps 6 in 3 double berths, full galley, head, and standing headroom ~1.85 m / 6'1"). The boat was popular in Scandinavia for its combination of speed, comfort, and value—often described as an "affordable classic" with a reputation for solid build quality and fun sailing (quick in light winds, capable in moderate conditions). Production was limited (exact numbers low, likely dozens),
