A Do-it-Yourself Wind Sensor

0

For more than 20 years, I always had bow-mounted vanes-a Telo Cat on my beach cat and a Windex sport on my Stiletto 27. The Telo Cat was sheltered under the forestay bridle and bowsprit and was never damaged. The long bows of the Stiletto kept the Windex out of harm’s way-although the Stiletto had a spinnaker, it reached faster than the wind and we always tacked downwind, jibing the chute inside like a jib and keeping the sail and sheets away from the bows. When I moved on to a PDQ32 catamaran, a cruising cat with a chute that is jibed outside, there was no place where either a sail or sheet couldn’t pulverize the vane in short order. I learned this the hard way, crumpling several commercial vanes. The solution was not to build something strong, but rather to build something that could flex with the assault and pop back up; a flexible wand topped with a length of yarn.

Mine is made from a few lengths of fiberglass tent pole from a child’s backyard tent and 3 inches of polyethylene airline tubing for pneumatic tools, although surely there are many possible variations. The basic elements are a short length of pole that can be clamped to a bow rail, a hinge created with a few inches of stiff but flexible tubing, and an 8- to 12-inch wand that can be knocked flat, only to pop up again. The yarn (wool or wool/acrylic blend) and cable ties are replaced annually, and the tubing every five years, as needed.

The do-it-yourself wind indicator has proven indestructible, having been flattened by the chute thousands of times during five years of cruising. It is not perfect. It is not as responsive or sensitive as the mini-vanes, it is harder to gauge the wind direction because of the droop, and the yarn can become wrapped around the vane (threading the yarn through the center of the wand, rather than attaching it with cable ties helps).

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.
