Build Your Own Fender Boards

0

Fender boards are almost a necessity when docking against pilings because without them, no matter how you position and secure your boat and fenders, movement of tide and boat will displace the position of the fenders relative to the piles. The result dinged topsides.

Fender boards, designed to ride outboard of two fenders, protect a much larger section of topsides much more effectively.

The simplest form of fender board as illustrated, is adequate for most needs. All that is needed is a 3- to 4-foot length of 2 x 4, 2 x 6, or 2 x 8 inches. As a guide, I’d start at 2 x 4 for a 20-foot boat, a 2 x 6 for a 30-footer, and a 2 x 8 for a 40-footer.

On a larger boat, you may want to use a slightly longer board, perhaps up

to 6 feet long. Anything longer than that, however, is likely to take two people to handle, and be a nuisance to store.

Just go the lumberyard and get normal “dimension”lumber, which may be any variety of softwood. Make sure that it doesn’t have any large knots in the middle of the board which might cause it to break under heavy loading. A hardwood like ash will take more abuse, but the extra weight can make it a handful for one person to handle.

A hole slightly larger than the diameter of the suspension or drop lines (say 9/16-inch hole for a -inch line), is drilled through the larger dimension at either end of the board, about 6inches from either end.

Next, round the ends of the plank and chamfer all edges. Your lines should be long enough to suspend the plank down to the waterline from whatever stanchions or cleats you plan to use.

After threading the lines through the holes, tie a figure-8 stopper knot at the bottom of each line, and you’re finished.

Because of the abuse fender boards are intended to take, painting or varnishing them is pretty much a waste of time. And, because you want a fender board to be as gentle as possible to your boat, complications like metal hanging straps or eye bolts are best avoided.

You can use your fender board with conventional round fenders, or you can purchase solid rubber cushions made specifically for attaching to 2 x 4 or 2 x 6 spars. Made by Taylor, they are available though most retail chandlers and mail order forms. In our experience they do not give the board quite as much standoff from the hull that a large round fender will, but because they are permanently attached to fender board, there is no risk that they will pop out of position, allowing the board to rest- and rub- against the topsides of your board.

The one embellishment you might wish to consider, if you have sufficient time and/or inclination, is a laminated fender board. This board is composed of three layers of 1 x 3-inch fir, hickory, or ash with the layers separated by 1/8-inch strips of wood epoxied in at either end with the object of creating a leaf-spring effect. I saw one of these years ago, and, though I don’t imagine it’s much more effective than a length of solid 2 x 6, it certainly looked impressive and showed a certain pride of ownership that a simpler board would lack. Only you can decide which sort of board would satisfy you.

Darrell Nicholson, editor of Practical Sailor, grew up boating on Miami’s Biscayne Bay on everything from prams to Morgan ketches. Two years out of Emory University, after a brief stint as a sportswriter, he set out from Miami aboard a 60-year-old wooden William Atkin ketch named Tosca. For 10 years, he and writer-photographer Theresa Gibbons explored the Caribbean, crossed the Pacific, and cruised Southeast Asia aboard Tosca, working along the way as journalists and documenting their adventures for various travel and sailing publications, including Cruising World, Sail, Sailing, Cruising Helmsman, and Sailing World. Upon his return to land life, Darrell became the associate editor, then senior editor at Cruising World magazine, where he worked for five years. Before taking on the editor’s position at Practical Sailor, Darrell was the editor of Offshore magazine, a boating-lifestyle magazine serving the New England area. Darrell has won multiple awards from Boating Writer’s International, including the Monk Farnham award for editorial excellence. He holds a U.S. Coast Guard 100-ton Master license and has worked as a harbor pilot and skippered a variety of commercial charter boats.
