The Large Windvane
Yes, that is a flying fish!
You only need to carry one Vane and we will recommend the vane that is best for you.
The large windvane is a lightweight ripstop nylon fabric stretched over an anodized aluminum tube frame. Its base is a casting that is attached to the steering unit with a quick release knob – easily spun off in a second or so.
Standard Vane
Over the years our Standard Vane has grown in height in order to produce better light air performance. Stowage of the Standard Vane is probably easiest – fits well on the back of a door.
Stubby Vane
Arches, radar masts, antennas, mizzens etc. can be interfering. For those we provide our Stubby Vane that is shorter and wider than the Standard. It produces comparable power and better accommodates aft deck obstacles.
Extendable ‘XT’ Vane
The XT Vane has been in production since the fall of 2015 and has been a success.
The Hydrovane can already perform in light airs because it has so little inherent friction, but there are conditions when more power is desirable – especially for modern big and fast boats that can sail downwind at 7 knots in a 10 knot breeze leaving little apparent wind for the Hydrovane to work with.
The XT Vane is extendable – can be raised or lowered. Raised for more power in lighter wind conditions. Lowered for stronger winds when the wind itself is providing plenty of power.
‘Leverage’ is the key. Leverage is the mechanical advantage or power gained by increasing the action of the lever. The Vane is the lever. Power of the Vane increases exponentially with increasing surface area and distance from its pivot point.
