Beruta - Hallberg-Rassy 31 Monson

The dream comes true


After spending two and a half years building Bruce Roberts steel Voyager 388, Arcadia (for all details see I had to sell the almost finished hull due to the divorce and the division of a matrimonial property. Well, it was sad, wasn't it? But the world did not end at that time. A few months later I recovered and start looking for purchasing a used fiberglass sailboat.

After reading multiple reviews (Sailnet, BoatUS) on blue water cruisers, studying the specs of the famous Mahina list's boats, I concentrated on two models, both of the same make, Swedish reputable boatbuilder, Hallberg Rassy, 35-foot Rasmus and 31-foot Monsun.

They both have solid fiberglass hull and polyvinyl cellular plastic cored deck, a long keel with a cut forefoot and a keel-attached rudder. Rasmus comes with two sail plans: a ketch and a sloop. Monsun is just a sloop. Both were manufactured in 1970s under Lloyd's supervision for "hull molding certificate". Both are known as excellent offshore passagemakers/circumnavigators. Monsun was a bestseller. There have been almost a thousand boats produced from 1974 till 1982.

There is a short story of "Golden Lady", the first Monsun owned by Kurt Bjorklund, who circumnavigated the globe three and a half times on Hallberg-Rassy's web site. The boat is now in Raa Museum in Sweden.

Planning to be a single handed sailor, I decided on a smaller boat. My short list of Monsuns offered by various online brokers ranged from 1974 to 1979. The asking prices were from $25,000 to $50,000. The boats were all over the world: Netherlands, Germany, Croatia, Turkey, Sweden, Scotland, Italy, Canada and US. I negotiated with the most dealers and ended up buying the simplest cheapest and oldest boat in the USA near Boston, named Moonwind. I called her Beruta.
