The mechanical constituents are housed within the frame. The steering lines are led inside the tubular members. The generously sized lever of the servo pendulum guarantees excellent mechanical advantage. The servo pendulum can be swung backwards out of the water. The weight is approximately 14kg depending on the mounting details. The design of the windvane installation and its mounting system are quite independent. Through this modular design concept it is possible to easily adapt it to all stern configurations: classical stern, externally mounted rudder, integral platform, canoe stern etc
