plough anchor (often spelled plow anchor) is a traditional, widely used boat anchor designed to mimic an agricultural plow. It is engineered to slice through marine vegetation and dig deep into the seabed to provide high holding power for cruising yachts and sailboats.
Core Design Types
Plough anchors generally fall into two distinct mechanical configurations:
Hinged Plough (CQR Style): This classic design features a pivoting shank that allows the boat to swing with wind or current changes without immediately dislodging the anchor fluke.
Rigid Plough (Delta Style): A modern evolution featuring a solid, one-piece construction with a weighted tip. It sets much faster than hinged models and is heavily favored for automated bow rollers.
Seabed Performance
Excellent In: Grass, weeds, mud, and hard sand where the sharp point can break the surface and bury the fluke.
Poor In: Soft, soupy silt (where it can drag) and solid rock or shale (where the point cannot find purchase).
Key Advantages
Self-Resetting: If wind shifts break the anchor loose, its geometric shape naturally forces it to roll over and re-bury itself.
Bow Roller Friendly: Both styles fit neatly onto standard bow pulpits, making deployment and retrieval seamless.
Are you looking to buy a new anchor for a specific boat size, or do you need help choosing between a plow anchor and a newer scoop-style anchor?
