The instructions on how to make a post float are online (post floats are made using a single float): picasaweb.google.com/versa dock.chris

Floating Dock Connectors – FDC 01 (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.

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

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.

Regular Pontoon

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.)

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.
