CC Series Mooring Buoys

CC Series Mooring Buoys

When using the CC series as a mooring ball, please follow these simple instructions to achieve the maximum use and durabililty of this product:

While the buoy is uninflated, lubricate both the tube and a rigid PVC pipe. Cut the pipe so it extends 3" (80 cm) beyond the buoy's top and bottom. Run a suitable size pin for your load through the top of the pipe. Attach the shackle to the chain at the bottom of the buoy.

CM Series Mooring Buoys

CM Series Mooring Buoys

CM Sizing – To figure out what size buoy you will need, determine the weight of the chain it must support. All chain has a stated weight per foot. Add another 25% to the total weight for safety. Always use chafing gear where mooring lines run through bow chocks or are likely to contact deck hardware. A thimble on the shackled end will prevent chafe at the buoy.

Fender Accessories

Fender Accessories

True-Fit fender holders are one of the most popular fender holder systems on the market. Its flexible modular design and easy installation make it versatile and reconfigurable at any time. Polyform high volume hand pumps are made to work with Polyform's unique air inflation valve.

Fender Covers

Fender Covers

Fender covers should be as tough as the fenders they protect. The Elite Fender Cover series uses a premium grade polyester yarn that is resistant to abrasion and UV exposure. Additionally, it resists water absorption better than other materials, keeping fenders manageably light when wet. The cover is woven on a special knitting machine that produces a seamless tube, meaning no seams to split. This method allows for a heavier, stronger yarn content resulting in a great fender cover that is built to last for many years, not just a season.

*The Polyform U.S. Fender Guide is to be used as a general guide. Common sense, as well as an understanding of your boat and mooring conditions, must be considered. The final responsibility has to be taken by the consumer due to the many variables out of Polyform's Control.

Mooring Guide

Mooring Guide

In a hard blow, the holding power of the mooring can be increased by lengthening the mooring pennant. This increases the scope of the mooring providing greater holding power – just be sure to check other boats in the moorage first to ensure you won't foul another moored boat. In adverse conditions, a second mooring pennant can be run to the top eye as a safety in case the primary pennant chafes through or fails. All shackles should be moused to prevent opening. Electricians' plastic tie wraps are an excellent means of securing a shackle.

How to Hang Boat Fenders

Tips on Hanging Fenders

Use at least three fenders when docking.

  1. Tie fenders to something solid like a stanchion base or deck cleat along the rail.
  2. Always hang fenders close enough to the surface of the water.
  3. Do not tie the fenders high. This could allow them to swing in a wide arc, causing them to end up on top of the dock rather than between the boat's hull and the dock where they're needed.

How to Arrange Boat Fenders for Docking

Tips on Docking

Use at least three fenders when docking.

  1. One fender at aft.
  2. One fender at maximum beam.
  3. One fender at fore.

How to Arrange Boat Fenders for Rafting

Tips on Rafting

  1. When rafting, the best fendering technique is to have the fenders in place on the boat already moored or at anchor.
  2. Position three standard fenders fairly close to maximum beam.
  3. Position two round A Series or LD Series buoys fore and aft to provide greater protection from boats tossing into each other.


Polyform fenders and buoys should be stored in a safe place out of direct sunlight.

What is a fender?

Sometimes referred to as a bumper, fenders protect a boat's topside from damage when tying up to the dock, or another boat by acting as a bumper between the object and your boat. Protecting the boat from bumping against the dock or another is the primary function of boat fenders.

Polyform is totally committed to producing the finest quality products to protect and preserve the investment in your boat.

Using Polyform Fenders for Docking and Rafting

Every docking situation is different, and Polyform fenders make docking safer but they cannot protect your boat in all maritime conditions. However, there are steps you can take to get the most protection from Polyform boat fenders. Tie your Polyform fenders to something solid like a stanchion base or deck cleat along the rail and don't tie to lifelines which are not designed to handle the pressure of rough or tidal conditions. Always hang fenders close enough to the surface of the water that they can't be pushed up by the movement of the boat bumping against the dock, and make sure to tie your fenders in as low as possible this prevents them from swinging in a wide arc and winding up on top of the dock, rather than between your hull and the dock where they belong.

Polyform Docking Tips

Use at least three boat dock fenders for best practice - one at maximum beam, one each at fore and aft. The three fenders keep your watercraft from bumping against dock and causing damage to the hull.

Polyform Rafting Tips

When rafting, the best fendering technique is to have the Polyform fenders in place on the boat already moored or at anchor. Group three standard fenders rather close to maximum beam, then position two round A Series or LD Series buoys fore and aft to provide greater protection from boats tossing into each other.

Polyform invented the inflatable buoy and is the oldest inflatable buoy and fender manufacturing company in the world, recognized all over the world. The quality of their fenders and buoys is consistent - with less than 0.5% of all of their products failing in the field, and they offer the widest selection of sizes and colors in the marine industry.
