Narai Mk I and Mk II

The Narai is a direct descendant of the 40 ft Rongo, the catamaran in which James Wharram made his pioneering crossing of the North Atlantic in 1959. She is 12.19 m long and 5.64 m wide.

The Mk I is the basic design. The Mk II has an extended center cabin for more accommodation. One set of plans includes the drawings for both.
