Comments owner:

The boat is in good shape, Engine was overhauled two years ago. All sails are good (she is sold with some older training sails in addition to full sail set). The boat got a brand new servo driver for the autopilot, and a RayMarine map/radar plotter.
The rotating keel is working fine.

A model of this one-of-a-kind boat built by Van De Stadt can be seen at the maritime museum in Amsterdam. This was the first sailboat in its class to cross the Atlantic Ocean computer assisted. Pieter Adriaans and the university of Amsterdam used this boat for its experiments from early 2000. After the project was done in 2008, the boat was sold to Tuned Rigs & Ropes. In 2009 the boat was rebuilds and repainted, using only the best equipment available, mainly carbon and titanium. Tuned used the boat as a show/demo boat until 2013.

This is a full carbon regatta boat in the Open 40 class, it is 12m long and 4m wide, needing 3.5m of water to sail, especially designed for OSTAR upwind cross Atlantic race. Open 40 is similar to Class 40, but with no restrictions to cost, solutions and materials. There are no other Open 40 boats in Norway, but hopefully “SOLO” and other Class 40 boats will let it compete. In short regattas the Open 40 will not be able to beat the Class 40 boats, but in long and open Ocean regattas the Open 40 got some advantages... Its speed record is 27.5 knots set by Pieter Adriaans. But since then boat has been fitted with a new custom made carbon mast almost 2 meters longer, and with a mast top genaker of 170sq/m… And the main sail increased to 100sq/m square top, and both carbon sails. The canting mast is removed as of new regulations, but the new rig is better than ever. Rather than using rod-rig, the boat now got Powerlight-PBO rigging. The rotating keel is still there fully functioning.
