Outboard models
Varuna and Joshua models

◄The Varuna and Joshua models combine the simplicity of the CapeHorn control mechanism, with a conventional installation mode, totally outboard. This allows installation of a CapeHorn on yachts with outboard rudders or in all cases when an installation through the hull is not practical (Joshua is for 35' and up).
The mounting arms of the Varuna model are 1" (25 mm ) dia. tube. They are 18 5/8" (473 mm ) apart and 22" (560 mm ) long (standard). The diagonal braces are 7/8" (22 mm ) dia. tube, 40" ( 1 m ) long.
The mounting arms of the Joshua model are 1.66" (41 mm ) dia. tube. They are 21" (533 mm ) apart and 22" (560 mm ) long (standard). The standard diagonal braces supplied are 1" (25 mm ) dia. tube, 60" ( 1,5 m ) long. Both models can be built with longer mounting arms and diagonal braces if needed.►

Installation ◄Installation of the outboard models is quite simple : it is only a matter of cutting the mounting arms and diagonal braces to the proper length and fastening them to the hull. Then the control lines are led to the wheel or tiller through blocks in the manner described aabove.

Length of the Mounting Arms

◄If the rudder is raked aft, the mounting arms (and diagonal braces) are cut so that the steering oar clears its trailing edge. If it is raked forward, the gear should allow free movement of the rudder head. The fittings supplied allow the mounting arms and diagonal braces to be mounted indifferently on a deck, hull or transom.
Naturally, the Varuna or the Joshua can be mounted directly to the transom

Height Above the Waterline
For optimum performance, the height of the mounting arms above the waterline should be between:
Varuna : 20"-30"(50-75 cm)
Joshua : 30"-46" (75-115 cm)
If the mounting arms have to be placed higher, a longer steering oar is supplied.

Modified Varuna or Joshua ◄►The horizontal control axle of the Varuna or Joshua can be made longer to place the steering oar at the end of an aft platform while keeping the vertical windvane tower forward, against the transom. (In this case, the mounting arms, no longer needed, are omitted.) The horizontal axis is fastened to the platform through U-Shaped straps. If needed, additional braces can be added.

Toucana

◄►Toucana is a hybrid between the two models (Jean-du-Sud and Varuna), designed for mounting under a boomkin (such as the Westsail 32). For larger yachts the Toucana can be built with the scantlings of the Spray-Joshua.
