This is a story that has a happy ending. 'Tarna' Tumlaren no 91, the third Tumlaren to be built in Australia in 1937, was effectively rescued from deriliction by James Frecheville and Tim Heaney in 2005. For those readers with a historical bent...(no pun intended) we have included information on Tum history in Australia. The Tumlaren or Tumlare (as it is pronounced in Sweden) class originated from a design brief from a Scandinavian by the name of Bent Kinde, in 1936. 
He commissioned Knud H. Reimers, a 27 year old boat builder to design and build the boat.
He wanted the boat to be simple and cheap to build, be able to handle rough seas and have an easy to manage rig, that was simple to sail.
The first Tumlaren from Bent’s drawing board was, ‘Aibe’ Tumlaren No.1;  

Uffa Fox the higly respected yachtsman and author, wrote in Wooden Boat, “the Tumlaren is the most advanced cruiser in the world”. Uffa Fox describing the balance and beauty of the characteristic bow and that gracefully rounded stern said, “Her concept was unusual and might take a while to catch on, for it takes years to break the habits and ideas that have grown and become accepted by sailors the world over.” 
The British term “Tumlaren stern” was adopted to describe a gracefully rounded stern. 

Equally famous English nautical publisher Adlard Coles, after owning and sailing the Tumlaren Zara, also owned the larger 32’ Cohoe built “Stor” Tumlaren and sailed her to victory in the 1950 transatlantic race. Stor is Swedish for “Large”.

The Tumlarens became popular all over the world and at the end of the 1930s boats were built and sailing in many countries in Europe, Africa, America, and Australia.
