Tumlaren was once called “The most advanced type of cruiser in the world” by another famous yacht designer, Uffa Fox!
Tumlaren was designed by Knud H Reimers in an attempt to marry the characteristics of a “koster”, longish and narrow, with those of the faster Square Meter Yachts that where very popular in Scandinavia at the time.
Tumlarens characteristics are very easy for, aft and water lines. And the yacht was like so many of Reimers designs designed on diagonals, all on diagonals, all of which cut the sections squarely a technique that makes it easier for the boat builder to do the laying down and fairing up.
The yacht has a sharp bow and a rounded stern that founded the British expression “Tumlaren stern” and other similar nautical expressions.
Tumlaren has an aft cockpit with just enough room to hold a helmsman. The main sheet is attached to a traveler on a wooden strong-back that separates the aft cockpit from the main cockpit. The interior accommodations are very Spartan with full length settee berths port and starboard and a v-berth forward the mast. In total allowing her to sleep four but this is very cramped with today’s measurements of yachts. Aft the port settee is normally equipped with a small alcohol stove and storage lockers. Additional storage lockers are found to starboard.
Tumlaren was also designed and built in a bigger version, the Stor Tumlaren (meaning “Large Tumlaren”) and in total there where more then 600 Tumlaren built.
Knud Reimers Tumlaren can today be found on all the worlds’ continents and in at least 24 countries. In Australia it early became a one design racing class and the building and measurement where adopted to locally availble wood types.
Today Tumlaren are very sought after classic yachts and prices vary from a couple of 100 USD for renovation projects to 30 000USD+ for nice examples.
New built Tumlaren are still available and among others a there is a Finish company named “M-Yachts” who still build them in wood.
