What is windvane steering?
One solution experiencing something of a renaissance, is windvane self-steering. When the wind acts on either side of this vane, it tips, transferring this action through the mechanism below to either a rudder or a servo pendulum which acts on the main rudder, altering the boat’s course.
What is a windvane on a sailboat?
The overall concept is simple: a non-electric device mounted on the boat’s transom has a vane that takes a signal from the wind. Based on this input, the boat is steered – by various mechanisms – on the apparent wind-based course you set.

What does a hydrovane do on a sailboat?
Hydrovane is a self-steering windvane system that is a completely independent mechanical system (ie. non-electrical) and steers the boat on a wind-based course. It is an auxiliary rudder type of windvane, meaning it has its semi-balanced rudder that is independent of the boat’s main steering system.
How do you use a Windvane?
The weather vane is made up of a tail and arrow. The tail fin catches the wind and the arrow points toward the direction the wind is blowing FROM. If the arrow on the weather vane is pointing north then it means there is a north wind. In other words, the wind is blowing from north to south.
How does a Windvane work?
To determine wind direction, a wind vane spins and points in the direction from which the wind is coming and generally has two parts, or ends: one that is usually shaped like an arrow and turns into the wind and one end that is wider so that it catches the breeze. Therefore a west wind is blowing from the west.
What does a wind vane cost?
Windvanes for small to medium sailboats can cost up to $10,000. Naturally, when an electronic autopilot that you can set with a button is priced similarly, sailors wonder if an old school, mechanical piece of gear is worth the investment.
What oil do you use in a hydrovane compressor?
The Hydrovane range of approved lubricants are: Fluid Force Red 2000 (A mineral lubricant for most installations under normal conditions). Fluid Force HPO (High Performance lubricant, a synthetic lubricant for hot and dusty environments and low ambient conditions).
Do weathervanes point into the wind?
Direction. The weather vane points toward the source of the wind because the balancing weight is at the point of the arrow. The surface area toward the back of the arrow is lighter, and therefore catches the breeze, and turns to distribute the air flow evenly on both sides of the arrow.
