For boats with transom or canoe stern. Integrated into the stern of the boat, the CapeHorn self-steering gear is virtually as strong as the boat itself.
The horizontal axle passes through the transom to locate the CapeHorn control arm or quadrant inside the lazarette, which makes it possible to lead control lines internally, through blocks on the boat’s steering quadrant, then jamming cleats in the cockpit; this avoids lines over the deck between the self-steering gear and the wheel.
Jean-du-Sud or Spray?
Jean-du-Sud for sailboats of 11 – 12 m (35′ – 40′) or less
Spray, for larger boats
The overall length is not a determining factor in the choice between the two models. The main criterion is in fact the amount of effort needed to move the rudder.
A boat 12m or more that is well balanced under sail, with spade rudder, tiller or low friction steering system, could be easily steered by a Jean-du-Sud. Whatever the model, the wetted area of the paddle is always proportional to the rudder of the boat to ensure adequate power to move it.
On a scoop stern or reverse transom with important rake, the vane tower of the Jean-du-Sud or the Spray can be located at the front end of the horizontal axle, passing through the deck.
