SVENHOLM - ex HOBBY was built in 1953 by Heidtmann in Hamburg to the well known Loki Class cruiser / racer design by Sparkman & Stephens. Professionally reconstructed in 1994, she is a solid and seaworthy cruiser; well equipped for family cruising and racing. SVENHOLM represents an easy to handle, beautiful pedigree classic in impressive condition.



Some dozen plus boats in this distinctive and popular class of S&S yawls were built; the first two LOKI and CHANCE in the USA – and believed still sailing. The majority were built in Germany either by Abeking and Rasmussen or as in this case by H Heidtmann in Hamburg - and both yards of renowned quality. The Loki class engendered a particular feeling in Olin Stephens to the extent he included it in his book “Lines” and we take the liberty of quoting the section verbatim:

“Loki is one of our custom designs whose basic lines have been used for a number sister ships, possibly six. The original boat was beautifully built of wood in in 1947 by Albert Lemos for a client who wished to cruise at sea with a small crew in a handy boat that was a smart sailer. As such, Loki became one of our smaller long distance/racers. Both Loki and several sisters have made long cruises in both the Atlantic and Pacific Oceans. Loki won her class in the I950 Bermuda race and others of the class have been successful in racing under various rules. If Loki's lines are in any way exceptional, it is primarily in her generous D/L ratio of 472, which to my recollection is the highest among S&S designs. The shape and balance of the ends seems normal and characteristic of our lines in general. She steers with a tiller and under power she is driven by a propeller in an aperture between deadwood and rudder. The yawl rig was chosen for ease of handling and shortening sail. The fractional head rig goes to about main mast height, although some of the later boats were built with masthead rigs. The accommodations provide a galley and icebox / chart table aft, a main cabin with transom berths amidships, and V berths in the forward stateroom.”
