Floating dock anchoring systems are critical for strength, maintenance, and durability. It is a common misconception that floating dock anchoring systems are for stability purposes. In fact, anchoring systems actually intend to keep floating docks in place. Some considerations taken prior to picking the right anchoring system(s) are as follows:
- Water Depth
- Distance dock needs to reside from shore
- Potential amount and frequency of water level fluctuations
- Amount of wind and wave loads the dock needs to withstand
- Dock configurations
- Local regulatory restrictions
Wahoo Docks has more than two decades of experience in the dock manufacturing industry. We understand the high pressure anchoring points need to withstand. That is exactly why we have engineered anchoring methods or systems to suit varying floating dock situations. You can combine more than one method. Generally, they are:
Pole & Sleeve
Pole & Sleeve – consists of a rigid sleeve that is attached to the dock through which slides a 4” diameter, 20’ pole. Through the sleeve, the pole buries itself to the ground. This type of anchoring can be done for bottoms that are not rocky. It is perfect for locations with heavy wind and wave loads. Pole & Sleev
e Anchoring gives the dock flexibility to move toward and away from the shore during seasonal water fluctuations.
Piles – may be composed of two piles or multi-piles in a variety of materials (wood, steel, concrete, and fiberglass) secured to the dock through pile rollers (UHMW-PE enclosed in an 8” aluminum box). It is somewhat the same as Pole & Sleeve except that it is suited for docks that require little to zero movement during seasonal water fluctuations. The piles also bury themselves in the ground.
Stiff Arm – done with cables running diagonally between stiff arms, with the gangway usu
ally serving as one ‘leg’ of the stiff arm. This type of anchoring provides a highly economical and effective means of dock anchoring for floating dock layouts that run primarily along the shoreline (without the need to run after seasonal water fluctuations). Several stiff arm designs are incorporated depending on the expected loads and overall length.
Cables – consist of cables in varying layouts to achieve different sets of feature benefits. Cable Anchoring is the most economical and flexible method we offer. We generally offer layouts in dock to shore, dead weights, combination, and self-adjusting. Cables are used in areas where the fluctuations and water depths are severe (when poles and piles required by the depth will just be too expensive to reach the bottom). Cables keep the floating docks in a flexible anchoring, making it ready to chase extreme fluctuations and heavy wind and wave loads.
