Manufacturing
Materials
The CapeHorn Integrated Self-Steering System is made of 316L stainless
steel tube and rod. The steering oar is now made of fiberglass but a teak paddle
can still be ordered on request. The steering oar
bushings are made of Teflon . 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 is fabricated according to measures
provided by the client : 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 ” dia. with wall of 3/16″ (4.75 mm ) on JdS
and Varuna , and is 1.25” dia. with wall of 1/4″ (6.35 mm ) on Spray and
Joshua. The stocks can be made of solid bar on request.
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.
Yves Gélinas takes care of the marketing, Éric
Sicotte manages production.
