The only design software program exclusively calibrated to polyurethane's unique properties, taking into account factors of stretch on three axis; horizontal, vertical, and diagonal at an inflated pressure of 3 pounds."

Like splitting the atom, Wing's proprietary software results from the high-speed collision of two brains

The only program of it's kind in the world, so far as we know; Wing's software is the combination of a world-renowned brain wave analyst and Wings own wizened polyurethane sages.


In the beginning, looking to expand his social network through river rafting even though he had never actually run a river one of our colleagues did the requisite research and prepared to purchase a raft and gear. Bill Wing happened to be in the outfitting store that day and introduced himself. Upon hearing Bill's name our man thumbed through his packet of file folders and pulling out a sheaf of magazine and newspaper articles inquired, "Can I take you to lunch?"

Invited to join an Electric Rafting Company trip the following week there were not only stunning canyon vistas, exciting rapids, and hikes up sparkling side creeks; but great food, hot-tubs, saunas and late-night (all night?) campfires featuring stories, music, and young women in bathing suits! At the end of the trip our rookie declared it was the most fun he'd ever had in his life!

As the friendship with Bill grew programs to assist in designing and fabricating river rafts out of polyurethane did so as well. Prior to this, pattern making was borrowed largely from sheet metal fabrication for heating ducts and stove pipes. Prototyping new designs was a matter of scribing, cutting, and pasting, or in our case welding, then inflating the material and standing back to analyze the results before making adjustments and trying again. Wing's new software streamlined the process by addressing a number of perplexing issues unique to polyurethane fabric; taking into account factors of stretch on three axis; horizontal, vertical, and diagonal at an inflated pressure of 3 pounds. To complicate matters the stretch factors differed in the warp and fill direction of the nylon weave, thus each pattern had to be oriented on the fabric 'just so' by the program to maximize fabric strength and integrity first and foremost, at the expense of minimizing scrap, ( a philosophy that still holds today.) Early results were impressive.

At one point Bill was pressed to come up with a unique white-water raft design involving variable tube geometry otherwise known as 'diminished' or 'tapered' tubes; Initially Bill begged off because it wouldn't be worth the time and scrapped material to nail those tapers. But with supreme effort yet another program was devised, Today, tapered or diminished tubes are incorporated into almost all Wing sponson design.

At present, Wing designers combine over two-hundred design specific versions of the original software with a number of other CAD programs, AutoCad, Patternsmith, Rhino, and SolidWorks among them, to accomplish a myriad of tasks, from initial design to finished product-for a rapidly growing list of applications beyond collars and tubes.

While strength and function of a diverse array of products are a growing source of pride here at Wing, some things never change unless it is for the better, for example, the 'lay' of a Wing sponson along a rigid hull. You'll see no hard-angled heating or air-conditioning ducts here; only smooth, tight, elegant lines, the result of years of hands-on commitment to creating 'the best' in form and function. And if you think we're full of hot air, well, take the Wing 'tube test' yourself. Survey a line of RIBS. The sponsons that blend most easily and naturally with the lines of the craft are likely ours, the ultimate in fit, form and function, and the happy result of two brains colliding.
