“Thetis” for sale, a unique 42 ft catamaran: Classical lines and atmosphere combined with high-tech features.
Thetis, a Tropic 12, was built by Samuel Boudon, boatyard Force la 3 in La Rochelle, France in 1990. Only one similar boat was built. She is unique.
I bought her in 1994 and had a few alterations made by a boatyard in Germany, which gave her her present exterior appearance and added a full size navigator's table in the saloon. Until 2005 Thetis was sailed in the North Sea, Baltic and Atlantic and into the Mediterranean Sea in 2006/7.
For the winters she was taken up river Ems to her home town, Haren, where she spent all her winters under a tent on the dry on my property. Time enough for regular maintenance and modernization.
Most of the sailing was done with a crew of two, myself together with my partner or a friend. Thetis can easily be handled by two persons only.
In all those years Thetis had proved herself sturdy enough for serious blue water sailing and we proceeded with our plans to take her across the Atlantic. This decision led to quite a few further changes concerning her bluewater sailing capabilities. Her old aluminium mast was exchanged in 2015 for a 16m carbon fibre one, longer than before. but also much lighter. Most of the standing rigging, apart from the forestay, is now dyneema. Parts of the halyards and the lifelines have been exchanged for dyneema, too. All of this has improved Thetis' general sailing performance and also her speed in light winds.
After a profound checkup and a lot of maintenance work (for example new seacocks throughout) in early 2016 we took Thetis' to the Canaries, the Cape Verdes and Barbados, where we arrived in Nov after a 14-day-crossing. On this long voyage Thetis has proved herself a willing, fast and safe boat. All the work including sail setting and trimming can be done from the cockpit by one person. We, the regular crew of two, arrived rested and relaxed and the boat had no failures at all. We also enjoyed the independence, permitted by enough solar-generated power and a watermaker.
For the last 6 months we have sailed her in the Caribbean.
With more than 50,000 miles sailed Thetis is certainly a safe, seaworthy boat equipped with everything useful on long-term sailing. At the same time she is a slender, light and therefore fast boat. Thetis is ready for the next 50.000. The regular maintenance due after the Caribbean sailing season is done during the present haul-out. There are no repairs pending.
As we are getting older our priorities are changing. Instead of an equilibrium of safety, speed and comfort the balance is bending more towards comfort and safety now. Thus we are looking for a larger, more comfortable boat and want to find a new owner for Thetis.
