MacArtney CORMAC M modular stainless steel winches are dependable and versatile systems capable of handling multiple marine applications and tasks. The winches feature a modular and compact design allowing for flexible system installation on vessels with confined deck space. The CORMAC M series includes five different standard winch models (CORMAC M2, M3, M4 and M5).

Designed and engineered for optimal durability CORMAC M winches require minimal maintenance. Customers can choose between a broad range of specifications including speed, pull, motor size and cable capacity.

CORMAC M winches come with several intelligent features which allow for accurate and effective equipment handling. A soft-start function makes the winch easy to handle, improves equipment manoeuvrability and protects the motor and gear.

CORMAC M2 and M3 winches always include an electrical slip ring. In addition, they come with a mechanically driven level wind.

CORMAC M4 and M5 come with an electrically driven level wind, allowing for significantly improved spooling performance, while making it possible to easily change cable diameter. CORMAC M4 and M5 winches are prepared for a Focal model 180-based electric/electro-optical slip ring.
