COST EFFECTIVE MONITOR-FREE MOORING

REVOLUTIONARY FLOATING MOORING SYSTEM

Monitor free mooring lines

Pile Ring is an innovative mooring device that provides constant and automatic line adjustment. 

The Pile Ring has been designed specifically to overcome weather and tidal mooring problems experienced by marina operators and boat owners alike.

They not only take care of the hour by hour and day by day adjustments required for changes in tide and water levels but are also on hand in the event of unpredictable and potentially disastrous weather bombs, tidal surges and flash floods which effect coastal and inland waterways and lakes from time to time. 

Pile Ring sits on the surface of the water around a mooring pile. Mooring ropes from your boat or craft are tied to the Pile Ring instead of the pile. The Pile Ring floats up and down the mooring pile at the same rate as your boat or craft and as such never needs adjusting. Your boat will always have tight and/or perfectly adjusted lines. 

You need never be caught out again.

PR400 & PR550

Design specifications

The PR400 & PR550 Pile Ring options  are constructed using an industrial grade one-piece moulding technique that seamlessly integrates a marine grade stainless steel hoop into a high quality Polyethylene float making it incredibly strong and long lasting.

1. INTERGRATED 19mm (3/4”) SOLID STAINLESS STEEL HOOP

A high-grade marine quality stainless steel hoop provides an extremely secure fastening point. The marine pile or the rope will give way long before the ring is even slightly distorted.

2. SUPER TOUGH ROTO-MOULDED POLYETHYLENE SHELL

The solid stainless steel hoop is kept well out of the water by the buoyant floating device. It also serves to protect the marine pile and boat from damage by acting as a float and fender.

3. UNIQUE SPACE SAVING NESTING DESIGN

The marine Pile Rings are cleverly designed to stack on top of each other. This makes them easy to handle and ship. It also provides space-saving storage for marinas.

4. CLOSED CELL FOAM FILLING

In addition to providing extra buoyancy, the closed cell foam prevents water ingress and ensures it is unsinkable even if it was cut in half.

5. MULTIPLE STRONG MOORING POINTS

The 4 strong pile ring tie-off points give a wide range of mooring configuration options for marinas, pontoons, and rivers, etc.

WHAT IS PILE RING?

Pile Ring is a floating mooring device which sits on the surface of the water about a mooring pile. Mooring ropes from your boat or craft are tied to the Pile Ring instead of the pile. The Pile Ring floats up and down the mooring pile at the same rate as your boat or craft and as such never needs adjusting. Your boat will always have tight and/or perfectly adjusted lines even in high tides, bad weather or storm surges. You need never be caught out again.

WHAT PROBLEM DOES PILE RING SOLVE?

Pile Rings take all the worry and anguish out of mooring your boat when there is the potential for inclement weather, sudden flooding, tidal anomalies, and storm surges as there is no need to tend to the lines. They are always at the right length and tension no matter what the situation. They also help to solve issues associated with berthing and docking maneuvers where wind and tide can cause sudden unexpected movement.

WHAT CAN YOU USE PILE RING FOR?

Pile Rings can be used to safely moor any floating boat, yacht, craft, vessel or equipment in any state of tide, current, weather or flood without the need for constant attention, monitoring or adjustment (within the constraints, limitations and heights of the pilings themselves).

HOW SHOULD I USE PILE RING?

The mooring line from the Pile Ring to your boat should be tight but not so tight that the Pile Ring starts to pull out of the water. It should remain properly afloat in a horizontal position. This provides “give” in the rope and allows the boat to ride with the waves, currents and movement of the water comfortably. As such it does not put undue strain on any ropes or marine hardware. It also ensures that the Pile Ring is not forcibly worn on one side against the piling.

N.B. Pile Rings are not designed for use on square concrete pilings as the sharp and abrasive concrete corners will wear into the polyethylene.

 

WHAT IS PILE RING MADE OF?

Pile Rings are rotationally moulded from high-quality virgin polyethylene (plastic) which is super strong and tough and almost indestructible. A single welded high grade 304 marine stainless steel hoop is inserted into the polyethylene float at time of moulding and this cannot be pulled out. The float is then filled with a closed cell polyurethane foam so that in the unlikely event of a puncture or leak or damage then the pile ring will still not sink.

N.B. 316 stainless steel is not used as it is not as strong as our particular grade of 304 stainless steel under these mooring conditions. The surface may display a tea-stain over time but it will not rust for a considerable number of years.

HOW STRONG IS PILE RING?

We have tested the Pile Ring to 3 tonnes (6000lbs) direct pull using an accurate Load Cell device. To give you some idea of how strong this is - your Ropes and your actual Pile are far more likely to break before the Pile Ring gets anywhere near its maximum load.

N.B. It is not the weight of the boat that counts but the pressure exerted on the ropes, pile and Pile Ring.

WHAT SIZES DOES PILE RING COME IN?

Pile Ring comes in three sizes:

  • PR400 which has approximately 400mm (15 ½“) inside diameter
  • PR550 which has approximately 550mm (21 ½“) inside diameter
  • PR750 which has approximately 750mm (29 ½“) inside diameter

N.B. Please make sure to measure your pilings at all states of tide before ordering and if in any doubt then please contact us for further guidance.

HOW LONG WILL PILE RING LAST?

Our Pile Rings are made from high quality, high grade materials and under normal usage and circumstances they should easily be lasting over ten years. Studies in New Zealand have shown many earlier designs to have lasted fifteen to twenty years plus. Please see our warranty terms and conditions for further information.

N.B. Pile Rings are not designed for use on square concrete pilings as the sharp and abrasive concrete corners will wear into the polyethylene.

WHAT MAINTENANCE DOES THE PILE RING NEED?

Pile Rings themselves do not require any maintenance, however, due to the localised nature and veracity of marine biofouling in your area it may be necessary to clean the Pile Ring from time to time. Our high quality polyethylene is impenetrable to marine biofouling and does not require any anti-fouling treatment, however, slime, weed, barnacles, mussels, oysters, etc. can attach themselves over time as with any other submerged surface. It is suggested that you inspect your Pile Rings regularly to check for marine growth. If the growth is heavy it will need scraping, cleaning, or water blasting to maintain the correct buoyancy, floatation and of course appearance.

Testimonials

“Our boat owners want safety, security and easy boat handling, so we install Pile Rings”

“There simply is no better choice of mooring apparatus if you’re looking for peace of mind in all tides or adverse weather situations”

“Pile Rings just make for a better boat handling experience”

“We like them because they’re not only maintenance-free themselves, but they also reduce the maintenance on the piles considerably”

“Worth every cent”

“Our purpose for the rings was to provide added value for our slip holders as an additional amenity, as well as protect our investment in our dock systems. Well, during storms and tidal surges, invariably huge strains come on the piling lines as they are not adjusted.  The owners often cannot get to the marina in time to fix the situation and our staff often have to take corrective action before a line parts and docks and boats get damaged.  So it also provides added security for the boat owner and the marina.”

US Naval Station Sailing Centre

“The Pile rings that Tony manufactures are the best product on the market. We were also very pleased with the quick service and competitive pricing.

Highly recommend.”

Gulf Harbour Marina
New Zealand

“Pile Ring is our preferred choice for pile moorings. They’re an indispensable, hassle-free solution for all kinds of tide and weather. Our customers like them because they don’t need to monitor their lines and they’re easy to use when arriving or leaving a berth. We like them as they’re easy to install, don’t need any maintenance and they’re very cost effective.”

Westhaven Marina

“As a marina operator, the Pile Rings give us what we want, which is peace of mind, productivity, and price”
