Laurin 31


Miguel Soler is the one man to thank for the Laurin 31 and without his initiative, this yacht would never have sailed the seas...

For some time Miguel had been dreaming of making his own yacht production. One day, he saw a L32 and was taken by her. He sought the name of the designer and in 1965 he met with Arvid Laurin to discuss drawings and build plans for the L32. Laurin informed, however, that the rights for building the L32 was held by Malmö Flygindustri, but suggested Miguel to buy the drawings of the legendary Laurin Koster "Casella II" for 500 SEK, which was very close to the L32 apart from some changes made to Laurin's original drawings by Malmö Flygindustri .

"Casella II" measured 9.65x2.88x1.55 m, and with a displacement around 5 ton and built in Mahogany on an Oak frame. "Casella II" was commissioned by Yngve Cassél as a follow on to another famous Laurin design - "Casella" - which was sold in the USA after her first Transatlantic passage. Yngve Cassel raced "Casella II" with fair results in both Bermuda Race and Transatlantic Race. In 1959 "Casella II" became the overall winner of the famous Around Gotland Race.

In other words, Miguel had - for 500 SEK - got himself a successful Ocean Racer and a safe bet for starting a successful Glasfiber production

In an old barn in Mörkö, Miguel started building the mould in 1966, working day and night for three month. Then he was advised by 2 "know it all guys" - Göran Ulvengren and Lennart Gradén - to produce a plug instead ! Miguel took the advice as well as a sledge hammer and disintegrated the mould, thus destroying 3 months of hard work ... Could be called a tough start...

When the plugs - hull, deck, cockpit, etc. - were completed they were moved to a barn at Ekholmsnäs, Lidingö.

The last thing to arrange was the keel. Here Miguel saved a lot of work, when Arvid Laurin suggested him to contact Fritjof Gustafsson in the "Rosättra Båtvarv", where Casella II was built in 1958. Her keel plug was still in store and consequently re-used for the L31. The keels - 2.200 kg - were then made - and galvanised - in Eskilstuna..

Then everything was ready for the DIY work could begin with an estimated 2 months for building the hull and deck.

Miguel made a simple contract with each new owner, in which was stipulated that the owner himself should contact Arvid Laurin for Royalty payments (600-700 SEK). The rent of the plugs were 2000 SEK

After the first 25 boats were produced in Lidingö, the plugs were relocated to Allemora at Riala-Sättra in 1973, where the last 11 were completed.

The production of the last boat in 1978 marked the end of the L31 MK1 (Long cabin). The boats were made as a mix between solid laminate hulls and sandwich constructionIn.

2002 Miguel finally got time to make his own boat, the boat which started the adventure for him back in 1965...

He made completely new plugs, giving a short cabin, heavier stern and redesigned cockpit. Further, the keel weight was increased by 300 kg now in lead instead of iron.

This model is unofficially referred to as the "Laurin 31 MK2" and so far 5 MK2s have been produced, bringing the total count of Laurin 31s to 40..... so far, as the plugs are still available for new boats.

The Laurin 31 is an excellent sea boat and many have done extended cruises, Ola Mossberg for one sailed his Noa-Noa (the picture) to the Amazonas and several others have crossed the oceans of the world.
