Sailboats Hallberg Rassy, Sweden HR40 sailing in US

The first new design under the name of Hallberg-Rassy was the Monsun 31, which was created in 1973.
The boat proved a great success, and 900 were built up to 1983. To meet the demand the area of the yard was doubled in 1975. The next design was the Hallberg-Rassy 41. This quickly became a trendsetter. This was the first boat with a proper walk through to the aft-cabin below deck. The basic principle for the layout, though greatly improved, is used to this day. One can question if this is due to routine or if this represents the optimal interior design of a centre-cockpit boat. On further study it becomes rather evident that this is indeed an optimal design.
The HR 41 had free passage from stem to stern below deck in one level. The galley was placed at starboard by the stairs, out of the ways from any passer-by, providing safety at sea and providing full headroom in the whole galley. The chart table on the opposite side was generous and with a real seat in the boats heading direction.
Further the HR 41 was a long distance vessel with the keel and rudder separated, and among other things a blue brim around the cockpit, which was slightly elevated, to give room for the passage below deck.
The size of the boat and the outfitting was spectacular for its time: Pressured water, heated water, shower, electric anchor winch, headsail furling system, two separate heads, a powerful engine, solid and elegant wooden interior and gracious lines.
All this is basic, though very much improved, to this day. 105 "HR 41" were built during a short but intense period from 1976 to1979, a few were also built until 1981. HR 38, designed in 1976/77, was also a trendsetter with the same interior concept, though a higher freeboard, and was the first boat with the characteristic blue stripe around the hull. The HR 352 from 1977/78 was a substantial sales success, with more than 800 built until 1989. This was the first time a designer had managed to combine, in a 35 foot boat, a walk through to the aft-cabin with spectacularly elegant lines.
HR 352 offered large- boat characteristics at a moderate price. Source and more Information: Hallberg-Rassy
