The B3-17.5 is an electric anchor chain windlass (capstan type) for marine vessels, engineered to handle anchor chain in the 17.5 mm calibre class. The unit develops a pulling force on the chain sprocket of around 12,150 N and is designed for anchoring depths up to 40 m, parameters suited to river vessels, harbor craft and small-to-medium seagoing ships.
Weighing 252 kg, the windlass is a deck-mounted assembly driven by an electric motor, replacing manual anchor handling with controlled powered retrieval — a critical safety and crew-efficiency upgrade. The product targets shipyards, vessel repair facilities, fleet operators and marine equipment distributors.
At $4,200 with a minimum order of one unit, the B3-17.5 fits both newbuild specifications and replacement installations during scheduled vessel refits, where matching the existing chain calibre allows a straightforward swap without re-engineering the anchor arrangement.
