Our recommendations are based upon decades of mooring experience on Lake Champlain
and compatibility requirements with the Town of Shelburne's mooring system.
A properly sized pennant line is many times stronger than the force exerted by the moored
boat. The greatest threat to mooring pennants is chafing. The following recommendation
overcomes the excessive wear typically seen where a pennant connects to the buoy.
Your pennant will connect to the buoy at the eye of a stainless steel swivel which is already
attached to the buoy. A seven-inch long eye (loop) spliced onto one end of your pennant is
fed through the eye of the swivel, and the pennant is then passed through the loop and
pulled tight.
No shackle should be used to attach your pennant to the swivel. Your pennant needs no
The mooring buoy is carefully ballasted to float just a few inches above the water. Putting
on too heavy a pennant will sink the mooring buoy. The recommended pennant has no
heavy and expensive metal components.
The swivel's eye will accept up to 5/8" line. We recommend polyester line, braided or
twisted, 1/2" (13mm) for boats up to 20 feet and 5/8" (16mm) for boats up to 35 feet.
Polyester is better than nylon for a pennant because of its low stretch. Minimum pennant
length should be 1 1/2 times the distance from the water to the deck, plus what is needed to
secure the line on the boat.
Chafe gear will extend the life of your pennant by reducing day-to-day wear at the point of
contact with the boat. Using chafe gear will not, by itself, cure the problem of sharp bends
over a deck, rough surfaces or improper chocks.
Attaching a pick-up buoy to your pennant is your option. At the end of the season when
you take your boat away, just take your pennant with you.
Trailerable boat owners beware. Most bow eyes are not intended for mooring a boat. The
single bolt stem can loosen at a mooring. Snap shackles have been known to fail. Consult
your boat dealer before using the bow eye to attach your pennant.
If you are sleeping on your boat in calm conditions and the slight thumping the buoy
against the hull bothers you, use your pennant to pull the buoy a few feet out of the water.
A sailor's best protection for his or her boat's security is constant vigilance. Your pennant
should be inspected regularly for signs of wear. Replacing worn line is important. If you will
be away for long periods, have a knowledgeable person check your boat.
material connecting the buoy to the anchor can stretch up to four times its unloaded
strength. It has an excellent abrasion resistance and can tolerate twisting. The system
uses rigid polyurethane thimbles to eliminate all metal-to-metal contact. The smooth
extension of the Hazelett rode also acts to keep the boat pointed into the wind instead
of yawing.
