A Marine Hall stockless anchor is a type of marine anchor made from cast steel, commonly used on ships. It's designed to be a versatile anchor, suitable for various sea bottom conditions, and comes in different types (A, B, C) primarily differentiated by the length of the anchor shank. These anchors are known for their rugged construction and ability to hold in sand and mud, making them a popular choice for ships.
Key features and characteristics:
Material: Cast steel, offering durability and strength.
Design: Stockless, meaning it doesn't have a stock (the horizontal bar at the top of some anchors).
Types: A, B, and C, with variations in the shank length.
Weight: Typically ranges from 40kg to 46,000kg, depending on the size and application.
Finishing: Often black tarred painted or hot dip galvanized for corrosion protection.
