Notes: Originated in Finland. Hai in Finnish, Haj in Swedish (meaning "shark"). The builder's site as well as some old reference materials we've seen use Haj when translating to English. These boats are commonly referred to as Haj boats in the US.\nFrom a number of different builders though Finnish one-design rules prohibit boats built with anything other than the originally specified materials (incl. wood spars and hull). Known as the REQUIN in France, where fiberglass hulls and aluminum spars are permitted.
