The PTW anchors are a registered trademark of Posidonia, the only company that produces SHHP anchors with qualified and certified welders. The product embodies the Made in Italy characteristics, with precision in execution, customization, and support, including 3D simulation assistance for retrieval.

Power anchorage

The PTW anchors are designed to ensure exceptional holding power, providing safety and stability for a wide range of vessels, including high-speed craft (HSC), yachts, superyachts, and workboats such as CTVs in the offshore market.

Speed

The weight range varies from 17 to 1500 kg. With an SHHP PTW anchor weighing 1,500 kg, you can have an anchor with the holding power equivalent to a 3-ton anchor, reducing the size and total weight of the anchoring equipment, including windlasses, winches, and chains.

Weight half of the mass

The PTW+ anchors are SHHP anchors (Super High Holding Power), also known as VHHP (Very High Holding Power), and have obtained approval from IACS classification societies. They guarantee a 50% reduction in weight compared to traditional anchors without compromising safety.

The PTW anchors are the only SHHP anchors certified by the China Classification Society (CCS). Additionally, PTW+ anchors are approved by major IACS classification societies, including ABS, BV, DNV, LR, RINA, RS, KR, as well as many river registers and Navy authorities.
