Capstans are used for safe and efficient handling of the mooring lines. Although they are mostly supplied as integrated part of our quick release mooring hook units, they often are produced as free standing vertical capstans as well. In these cases they are used in combination with, for instance: bollards or basic quick release hooks. Our standard range of capstans are driven by high-quality electrical motors.


A mooring capstan is a permanent structure used for boat or ship mooring when reaching a port or dock. It is used to get the mooring lines from the ship to the berth. At Straatman, we supply capstans as an integrated part of our quick release mooring hook units. We can also provide them as free-standing vertical capstans, in combination with bollards or basic quick release hooks. In short: we can customize our capstans to suit any application and vessel type.
