Proven Performance Since 1988
Pyramid Mooring Anchor
Designed to penetrate the bottom and prevent dragging.
The Dor-Mor Pyramid Mooring Anchor rapidly penetrates the bottom due to the high point loading of its compact size and shape. Our product achieves approximately 10 times its dry weight in holding power once it has penetrated the bottom and is completely covered with bottom material. The large surface area of the pyramid shape has a high suction effect which increases the deeper it sets.

Conventional Mooring Anchor
Holding Power Test Data
Comparative holding power based on actual independent testing at Newport, Rhode Island, USA
Tests conducted during June, 1994 at 3:1 scope (3 times water depth in chain).
The Tests revealed three important facts:
- Only the Dor-Mor Pyramid had completely imbedded itself in the bottom.
- The embedded Dor-Mor Pyramid achieves approximately 10 times its weight in holding power at 3:1 scope.
- The Dor-Mor Pyramid Mooring anchor was the only mooring anchor which dug again into the bottom and reset itself after the Tug broke it free.
* The pull test was conducted with the Dor-Mor Pyramid Anchor being attached with only 2.2 to 1 scope. At that ratio had holding power of 4,500 lb. All other devices being attached with 3: 1 scope or more. Calculations have been interpolated to extend the Dor-Mor anchor pull to the 3:1 scope data. All of these anchors had been put in the water and left for some period of time with no special installation procedure prior to the test.

We can supply individual anchors or a complete, custom designed mooring system for your particular application.
The holding power of a mooring weight is affected by the following factors: whether or not it is set (imbedded in the bottom); the proper amount of scope is used; the weight and shape of the boat; the condition of the chain, hardware and line used; the wind, wave, tide and current conditions at any given moment. DOR-MOR, Inc. has no control over these factors and, therefore, assumes no liability for loss or damage in the utilization of our products.
