DRAfter Series

Model e.g. DRAfter 2500

Multi-function shallow-draft tug designs with heavy-duty aft towing gear and deck cranes for towing, anchor handling and nearshore infrastructure work.

Description

The DRAfter series are multi-function, shallow draft tug designs for operations in coastal and protected waters. Equipped with heavy duty aft towing gear and deck cranes, they are suitable for towing, anchor handling and maintaining nearshore infrastructure.

Large accommodations and wide, unobstructed flat aft decks let the vessels act as a primary work platform when operating independently or as a support tug to larger vessels. They are typically offered with twin-screw propulsion but can be configured with a triple screw arrangement for extremely shallow water. DRAfter tugs are designated by length, e.g. DRAfter 2500, with power, draft and dimensions set by the intended service. With a forward winch they can also perform ship handling.
