While the Nordica 20 and the Halman 20 are often mistaken for each other and according to some sources, the design of the Halman 20 was inspired by the Nordica 20. Atleast a few Halman owners thought it was the other way around. They are two different boats though, built by two different manufacturers. One significant difference is in the hull construction. The Nordica was built from two halves and joined during construction while the Halman was a single pc hull layup. It’s hard to see much of this when they’re in the water.
The Nordica 20 specs are: L.O.A. is 19’ 6” - LWL is 16’ 6” - Beam is 7’ 8” - Draft (full keel) is 3’ 3” - Displacement is 2520 lbs. - Ballast is 1026 lbs. - Mast height above W/L is 30’ 0” and was offered with a 4-10 hp diesel engine option. Sleeps 4 with a compact v-berth forward and two settee bunks in the main cabin. Sail area is 188 sq. ft. The Halman 20 by comparison shows just 20 lbs less displacement, 26 lbs less ballast, has a 2’ 10” draft and by visual comparison of the spec pages, has a slightly more “stepped” forefoot on the keel profile when compared to the Nordica.
