the fixing, otherwise the ring will slip around the rope. The lanyards should be as short as possible
consistent with freedom to twist, and secure the free ends. This will ensure self-alignment of the
generator shaft with the water turbine towrope. There has to be freedom to turn to port and starboard to
follow the boat, otherwise the bearings are excessively loaded. If the stern pulpit, or other structure
used as a mounting, is not robust and absolutely rigid, it is recommended that it be counter-braced to
some strong point on the boat in order to prevent damage should the tow rope and water turbine
become snagged. The generator and gimbal ring are designed to withstand an ultimate load of 450 kg
(1000 lb) and the shaft connector is designed to break at 300 kg (700 lb).
Remember to use strong
enough lanyards and knots.

Tow Turbine:
Attach the acetyl shaft connector and shackle to the Aquair shaft with the M6 cap screw
and shake-proof washer provided. Attach towrope to shackle and tow turbine, we suggest a fisherman’s
bend knot with the free ends whipped to the rope. These connections need to be neat and tidy to give
smooth operation avoiding extraneous noises and vibration.
Permanent Deck Mount:
This is available for those wishing to make a fixed installation of the Aquair.
The unit consists of a welded stainless steel frame in which the Aquair is mounted. This provides a very
neat arrangement where the existing gimbal ring provides horizontal movement and the deck mount
pivots allow vertical movement. This allows the application of the Aquair where no stem rail or structure
is present, such as on a double-ended yacht or a catamaran. The unit is simply bolted through the
deck. Note that where possible it is preferable to mount the gimbal ring with lanyards which are both
cheaper and provide better shock absorption.
