Fluke-style anchors, also known as Danforth anchors, were developed by Richard Danforth for use by landing craft in WWII. His design met the need for a lightweight, easy to handle anchor that is effective in different types of seabeds.
Parts of Fluke-Style Anchors
Fluke-style anchors consist of two triangular flukes attached to a stock, and a shank that connects the anchor to the anchor line or chain. The flukes have sharp, pointed tips and are designed to dig into the seabed when the anchor is set. The stock provides stability and helps the anchor orient itself correctly. Fluke-style anchors also have a crown, which consists of two small plates at the point where the shank hinges on the stock. The crown limits the angle of the flukes in relation to the shank.
Where do fluke-style anchors work best?
Fluke-style anchors are particularly effective in sandy or muddy seabeds. The sharp flukes can penetrate into the loose sediment, creating a secure hold. When properly set, the anchor's design allows it to bury itself deeper as the boat pulls on the rode (anchor line or chain). This additional burying helps increase the holding power and ensures stability in changing tidal or wind conditions.
Applications for Fluke-Style Anchors
These anchors are widely used by small to medium sized boats. They are favored for their high holding power-to-weight ratio and their ability to reset themselves if they happen to break free due to changing conditions.
