Capstans are essential for the safe and efficient handling of mooring lines. While they are often integrated into our quick-release mooring hook units, they are also available as standalone vertical capstans. In such cases, they are typically used alongside bollards or basic quick-release hooks. Our standard capstans are powered by high-quality electric motors, ensuring reliable and smooth operation.
A mooring capstan is a permanent fixture used to secure boats or ships when docking at a port or quay. It facilitates the transfer of mooring lines from the vessel to the berth. At Straatman, capstans are available both as integrated components of our quick-release mooring hook units and as standalone vertical capstans, which can be combined with bollards or basic quick-release hooks. We offer fully customizable solutions to suit any vessel type or application.
