Installation Forestay installation to deck 1. The forestay is fitted with a stout torsion-resistant lower toggle (see fig. 9.2). This is attached to the stem- head fitting. The toggle can be fitted either athwartships or fore-and-aft. 2. Check that the stem-head fitting and the toggle are suited (see table below). The stem-head fitting must be able to withstand a torque of 1200 Nm for Wire Ø...
Installation Hydraulic motor The drive unit and hydraulic motor are tested before delivery. The hydraulic motor is a Danfoss OMM 20 cm /revolution. Maximum recommended pressure, p=140 bar. The oil flow, Q=20 litres/min. gives a nominal speed n=40 rpm. ...
Hydraulic hoses not supplied. (See fig. 12.1). Hydraulic hoses for installation below deck are Connecting threads are G 1/2”. (See fig. 11.1). Use hydraulic hoses of good quality corresponding so SAE 100R7/-ISO3949. Minimum dimension 1/2”. Minimum working pressure 140 bar. Minimum recommended bending radius 150 mm (6”).
The sail The sail should be made for rolling up on the starboard side of the luff foil. Any sun-strip should therefore be on the starboard side of the sail. A high cut clew can give a constant sheet angle even when reefing. The luff tape ”hard line”...
Important points to remember before sailing The sail rolls on to the starboard side of the luff extrusion. The halyard angles out 5–10° from the forestay with sail set. All sails used have the right total luff length. See page 31. ...
