South Atlantic Self Steering S-234

Click to enlarge

The S 243 is an auxiliary rudder system. This principle offers a good sensitivity-strength balance. Because it is a completely independent steering system it will provide its certain amount of steering power, tempered for the conditions, to any boat .

The system consists of a [sensor-vane] which transmits the change in the wind direction to the windvane rudder. The rudder is not attached to the tiller by [lines]. It can be used as an emergency rudder or to steer the sail boat.

" No lines in cockpit – Independent from main steering – and not attached or connected to it.
" No extra gear – No servo blade or no trimtab – Just a vane powering a semi balanced rudder
" The natural stability makes for a better ride through the worst of conditions.

Advantages of our Windvane
" Adjustable vane (for strong or light wind)
" Easy to start and stop operating
" Course adjustment - manual /distant
" Detach able rudder

"Length of air vane mast, pendulum shaft and tiller arm customised to fit each individual boat.
