Cassens & Plath Sigma

Steering- and Bearing Compass, especially for larger steel yachts.

Compensation, illumination, protection hood and shadow pin are included in delivery.

The Sigma Compass is available either coated in black or white.

Typically mounted on the sliding hatch or the garage, so that reading is easy from the helmsman´s position.

Sigma is easily removed from the base plate and then it can be stored below deck.

An optional azimuth device can be installed at the compass. So it is possible to take relative- and compass bearings. The shadow pin, included in delivery, serves to deviation checks.
