Kohler Designs Voyager (KD 122)

Description

The Kohler Designs Voyager (also known as the Voyager or KD 122 Voyager) is a modern plywood/epoxy cruising catamaran designed by Bernd Kohler (a German multihull specialist through his K-designs series, with plans sold via sites like Duckworks and ikarus342000.org). It's a 40-foot (12 m) bridge-deck catamaran optimized for amateur or solo builders, emphasizing simplicity, affordability, seaworthiness for coastal/offshore use, and good load-carrying for liveaboard or family cruising. The design uses stitch-and-glue plywood construction with fiberglass/epoxy sheathing, asymmetric hulls for efficiency, a fractional sloop rig (often with rotating mast or A-frame options in builds), and a spacious layout (multiple berths, saloon, galley, heads). It's part of Kohler's KD (K-Design) line (e.g., KD 650, KD 860), with the Voyager (KD 122) as a larger, more capable cruiser. Production is plans-based only—no factory builds—with at least one well-documented example launched in Italy (built solo by owner Domenico, with videos of flipping/launching shared on Facebook and YouTube). Other builds are discussed in K-designs multihull groups (e.g., groups.io), with owners praising comfort, stability, and performance (e.g., handles like an asymmetric beach cat that points high).
