Floating Dock Connectors – FDC01
(Dock connectors should be positioned in-between floats and therefore through two lugs, not on the corner of the pontoon through one lug)

Shore Bars
If using this system it would be necessary to use sideways bracing to ensure horizontal stability.

The Danforth or Sand anchor. This type of anchor has large flukes which give it a lot of holding power for its weight. It is considered best in sand, gravel and
- mud. These type of anchors are not
recommended for rocky, clay or grassy bottoms. The Spade anchor This anchor is similar to the plough anchor in appearance. However the blade is convex giving greater holding power. The shaped tip assists with digging in and penetrating the seabed. The Plough anchor The original plough anchor was the CQR This anchor works well in a variety of conditions with good holding power. Generally they reset well. They can have difficulty penetrating weedy bottoms and don’t hold well in soft mud. The Bugel anchor These anchors have a flat pointed blade to penetrate the bottom and a roll bar to ensure the anchor turns and sets the right way up The Claw anchor Generally referred to as the Bruce anchor these anchors work well in most types of bottom except soft mud and reset well. Whilst the holding power is good it’s generally considered slightly less than a plough anchor. Grapnel anchor The design is non-burying with
- ne or more flukes digging in and
the remainder above the seabed. Grapnels rarely have enough fluke area to develop much hold in sand, clay, or mud.
Popular Anchors
This information is for reference only and the responsibility for choosing anchor type, and weight is the sole responsibility of the user. Always take advice on the weight of chain required and we recommend a minimum chain length per anchor of 6 x maximum water depth.

Railway Wagon Wheels
We have also seen the successful deployment of old Railway wagon wheels for heavy offshore use. These require specialist installation.

Lined Lake Moorings
FRONT VIEW
Padded large bags are filled with clumps of chains and positioned at the bottom of the lake, this means that the lake lining is protected from sharp edges and will not be penetrated. Concrete blocks are also a possibility for this type of mooring.

Drive on Dock
(As seen on the image above, the stern rope is loosened to allow for the lowering of the floats when a boat drives up onto the dock.)
SLIDE 16
Ensure a solid attachment to the shore and fasten very tight to guarantee proper stability, anchor to the sea bed as normal at the far end of the pontoon.
