*These dimensions can be modified on special order. ManufacturingMaterials
The CapeHorn Integrated Self-Steering System is made of 316L stainless steel tube and rod. The steering oar is teak. The windvane and steering oar bushings are made of Teflon for optimum light air performance. Other plastic parts are Delrin, Nylatron and UHMW (Ultra-High Molecular Weight polymer). The light air windvane is nylon spinnaker cloth over stainless wire and the heavy weather vane is an anodized aluminum blade. Weight (of standard model) is about 35 pounds for the Jean-du-Sud and Varuna and about 55 for the Spray and Joshua. Each Unit Custom Built
In order to provide the best integration possible between the windvane and the boat, the dimensions of each segment can be modified as needed : the length of the horizontal axis (LMT), the height of the windvane tower, and the size of the servo-pendulum. Scantlings
Likewise, the wall thickness of the tubes used in construction is in proportion with the size and displacement of each boat. When maximum strength is needed, a thicker wall is used; conversely, if weight needs to be saved, a thinner tube will be used.
The CapeHorn is over-built. The wall of all stress-bearing tubes can be a maximum 1/8" (3 mm ) thick (11 GA). The horizontal control axle is made of a tube 1.9" (48 mm ) OD on Jean-du-Sud , and 2.5" (63 mm ) on Spray . The steering oar stock is 1" (25 mm ) solid rod on JdS and Varuna , and 1.25" (32 mm ) on Spray and Joshua . CapeHorn Marine Products
CapeHorn Marine Products was formed in July 1989, to develop and manufacture the self-steering system Yves Gélinas designed and so conclusively tested around the world by way of the Southern Ocean and Cape Horn.
The manufacturing plant is in Oka, Québec. (Oka is 50 km west of Montréal on the North shore of the Ottawa River. Customers can sail to our shop.) Yves Gélinas takes care of the marketing, Éric Sicotte manages production.  CapeHorn Marine Products
