[1][3][4] The Nash 26 is a small recreational keelboat, built predominantly of fiberglass, with wood trim.

It has a masthead sloop rig, a transom-hung rudder and a fixed fin keel.

Despite the priority placed on interior space, it still has acceptable proportions for a cruising boat, although some later Nash 26s appear to have been built with a slightly boxy-looking cabin.
