Pyramid Mooring Anchors

Pyramid Mooring Anchor - One-Piece Cast Iron Permanent Mooring Anchor, Made in USA, Hurricane Tested

The DOR-MOR Pyramid Mooring Anchor is a purpose-built permanent mooring solution, constructed from a single-piece cast iron, engineered to deliver exceptional holding power through a combination of intelligent geometry and raw mass. Its compact pyramid shape generates high point loading, allowing it to rapidly penetrate virtually any bottom material, so it sets fast and deep from the moment it hits the seabed.

Once covered, the large surface area of the pyramid creates a powerful suction effect that only intensifies the deeper the anchor sets, making it extremely difficult to dislodge even under hurricane conditions. Boaters who have used these anchors report that after setting, the shank, shackle, and top chain links are often fully buried, confirming deep, reliable penetration. The short-shank design is an intentional feature that permits mooring in shallow water while minimizing chain wrap-up, reducing the risk of chain fouling or hull damage during tidal changes or strong current reversals.

Made in the USA and battle-tested on the rugged coast of Maine since 1988, DOR-MOR pyramid anchors are built for permanent mooring buoy installations and have held through major storms, including direct hurricane events. The large diameter eye resists rust-out over time and is sized to accommodate a proper shackle and chain appropriate to the recommended mooring weight for your anchor size. Every anchor is backed by a 10-year rust-out guarantee, reflecting the manufacturer's confidence in its long-term durability.
