An AC-14 High Holding Power (HHP) anchor is a type of stockless anchor, designed for high holding power in various seabed conditions. It's a popular choice for large ships and vessels due to its good weight-to-performance ratio and ability to quickly dig into different types of soil like mud, soil, sand, and sandstone.
Here's a more detailed breakdown:
Stockless: Unlike traditional anchors with a stock (a crossbar), AC-14 anchors have a single piece casting for the crown, arms, and flukes, making them easier to handle and stow.
High Holding Power (HHP): AC-14 anchors are designed to have a high holding power, meaning they can resist the forces acting on them (like wind and current) when anchored.
Versatile: They can be used in a variety of seabeds, including mud, soil, sand, and sandstone.
Finishes: Available in blacking painting or galvanization.
