Description
The Spek anchor is a type of stockless anchor that has been improved to have a lower center of gravity compared to the hall anchor. The core of the anchor head is positioned at the centerline of the pin, extending towards the bottom. The structure of the Spek anchor is characterized by an anchor crown plate and reinforcing ribs on its crown, enabling easy grounding and enhanced stability.
Its intelligent design makes it perfectly suited for fitting into an anchor pocket, while ensuring that its flukes remain naturally oriented upwards and promptly overturn upon contact with hull plates to prevent damage to shell plating.
Surface: black tarred painting, hot-dip galvanized, Dacromet
Certificate available for ABS, BV, LRS, DNV, IRS, RINA, RS, CCS, KR, NK
