Mooring Buoys

This is a Soft Foam Mooring Buoy with line storage nest and pickup buoy storage hole. We use heat applied letters and numbers to give you a neat and clean look. We can add on a buoy boot ($35) to ensure the hardware from the pennant does not come in contact with your boat. It also keeps the rim of the buoy from wearing thin as the boat moves while on the mooring.

Mooring Pennants

Above is an example of our custom wye shaped pennant, spliced in house. We use USA made line, all stainless hardware. All splices are load tested to 2000 lbs and then whipped closed. The cordura chafe sleeve is custom sized to your boat and whipped into position. An additional 1 foot piece of cordura chafe is included which can be moved to the exact area of the chock or other chafe points. 3" toggle floats keep the body of the pennant from getting caught under the ball and chain. The integrated stainless steel jaw to eye swivel allows any twists in the mooring system to unwind before damaging the pennant line. Tie down lines secure the loop splices and keep your pennant tight to your cleat. This modular design of locking spliced loops allows you to have independent arms, to if one fails you have an additional one for back up. The arms are able to be replaced separately if one should get damage without any re-splicing.

Mushroom Anchors

There are 3 basic types of mushroom anchors available, imported mushrooms, Seaboard USA mushrooms and Annes USA counterweighted head mushrooms.

The imported mushroom anchors typically come from China and India. The quality of the shafts and casting varies from each distributor. The imported anchors that AMC sells are hand pick from our vendor by us. We resonance test each anchor we sell to ensure good casting between the steel shaft and cast iron dish (we resonance test all anchors we sell).


Seaboard USA mushroom anchors are forged in USA from domestic and imported components. The eye size is the same as an imported anchor which typically measures 28mm or 1 1/8". The cost is double that of imported anchors

As you shop around ask for what type of anchor and what size is the eye. Whether an anchor is imported or domestic the size of the eye dictates how long it will last.

AMC Reinforced Concrete

We have 3,000, 4,000, 6,000 and 8,000 lb AMC cement blocks. Aquidneck Mooring Company blocks are made with rebar reinforced steel and solid 1 3/4" steel rod, completely welded throughout. Our blocks are 5' in diameter. We designed it round to prevent the bottom chain from getting tangled around the corners. The competition only sells square blocks. AMC blocks are made with high psi concrete so they are stronger. Our low profile design increases holding power compared to higher blocks which have a higher center of gravity and tend to flip over easier. We recess the 1 3/4" attachment eye inside of center of block and make double attachment eyes for long life. Aquidneck Mooring Company's rebar reinforced blocks are so good that we guarantee them for life if we annually maintain the mooring for you.

Helical Embedment

Our helical embedment anchors get their holding power from the soils they are screwed into. Softer soils provide less holding, so buyers should up-size their anchor selection if they plan to install the anchor in softer soils.

Harbor, weather conditions, and soil type are all factors that should be take into consideration when determining your anchor. Please consider exposure, soil, and extreme weather conditions when selecting the size.

Elastic Mooring Tech

Elastic moorings nearly eliminate the severe stresses and abrupt motions of vessels anchored with chain. In extreme weather, elastic mooring systems can expand up to 30% of the slack length to eliminate the destructive jerking motion typical of taut inflexible chain mooring.

The elastic mooring reduces the shock load and has a life expectancy of 10+ yrs. The floating downline stays suspended thru the water column, so it preserves the sea bed and marine life, eliminating “crop circles”. Eelgrass meadows can be a natural carbon sink, removing carbon dioxide from the atmosphere and storing it in sediments while improving water quality and reducing coastal shoreline erosion.
