  • Study Plans (Both Are Covered Here for Simplicity)
    Your ‘Slingshot 16’ and ‘Slingshot 19’ Trimaran Free Study Plans (Both are Covered Here For Simplicity) …from Designer / Builder / Sometimes Sailor Frank Smoot (AKA ‘Trimaran Frank’) About The Boats: The ‘Slingshot 16’ is a 1-2 seater trimaran, and the ‘Slingshot 19’ is a 2-3 seater trimaran. Both boats been developed to sail in perfect balance. With the 2-seater setup, but boat can remain in ideal helm balance whether soloing or carrying a passenger, thanks to a unique sliding seat arrangement. You can also rig them both with several very different kinds of sail rigs, and with either folding or fixed amas. NOTE: The Slingshot 19 plans include full details to build both the folding akas and 19’ amas. NOTE: The basic Slingshot 16 plans include construction details for the standard 14’ cruising amas and one-piece (non-folding) akas. Supplementary plans are also available that include full construction details for the larger 16’ performance amas and also for folding akas for the Slingshot 16. NOTE: Plans for the 2-seater version of the Slingshot 16 are not yet available, but are in the works. About the speed of these two trimarans: You may not want to go 14 mph, but it’s nice to know your boat can safely do that. (It could probably do more, but somehow that seems fast enough for me.) You can choose among 5 different sail rigs, either stayed or freestanding (unstayed). And you can initially build the Slingshot 19 with fixed akas, then later convert to folding akas (for easy trailering) if you wish.

  • Excerpts from a Sailor's Wind Journal
    A Fine Reach Home: Excerpts from a Sailor’s Wind Journal Lynn Fels English Bay, 1976, International 14 We surface amidst sodden sails, shouting in surprise and haste. “Are you okay?” “Where are you?” “Hang on to the gunwale, no wait, swim the bow into the wind, now swim over here, we’ll bring her up together.” Martin and I, skipper and crew, throw our weight onto the centerboard. The boat reluc- tantly responds, the mast tilting skyward, rising from the sea. I taste the salt of ocean spray that catches me unaware after so many years of sailing fresh-waters. Equilibrium restored, seawater emptying through the automatic bailers, our sailboat moves across the water in ecological tension between human, craft, wind, and geography. Martin tends to the navigation, attentive weight- ing of hand on tiller, as I set the jib and cleat the sheet. Shifting body weight, secured by the trapeze,I feel the arc of body, an embodied inter- pretation of movement in response to the wind’s presence in the tautness of the sails. Sailing in the various conditions of wind requires an instinctive chore- ography of release and defiance, surrender and embrace, by skipper and crew. 180 Canadian Journal of Environmental Education, 13 (2), 2008 This is what holds me to task, as I swing in and out of the boat secured to the mast by the trapeze wire that holds me in place. “Wind’s coming! Trapeze!” Martin yells, but I am already in concert with the wind, welcoming its arrival, anticipating its departure. Sailing, a harnessing of wind with canvas to propel a sailboat across dis- tances of water, in winds shaped by landforms, airflow and temperature, requires constant renegotiation by skipper and crew in response to the wind’s changeable presence.

  • ANALYSIS of DYNAMIC TRAPEZE SAILING TECHNIQUES Thor Besier and Ross Sanders' Department of Human Movement and Exercise Science
    ANALYSIS OF DYNAMIC TRAPEZE SAILING TECHNIQUES Thor Besier and Ross Sanders' Department of Human Movement and Exercise Science, University of Western Australia, Perth 1School of Biomedical and Sports Science, Edith Cowan University, Perth. The purpose of this study was to simulate dynamic trapeze sailing to determine the stress placed on the musculoskeletal system. Muscle activations from the erector spinae and external oblique musculature were measured using electromyography and combined with joint kinematics to analyse several dynamic trapeze sailing postures. Dynamic trapeze sailing involved stresses to the musculoskeletal system that previous studies failed to indicate. These stresses included constant use of external oblique and erector spinae musculature to stabilise the trunk, rapid extensionfrotation of the trunk coupled with eccentric muscle contraction during dynamic body pumping techniques, and increases in muscle activations owing to asymmetrical body positions. These results have implications for trapeze harness design and injury prevention. g KEY WORDS: sailing, electromyography. 41 \ INTRODUCTION: Trapeze sailing is a technique used by certain classes of dinghies (including the Tornado, 49er, and 470.01ympic class) to maintain the boat in an upright position, thereby maximising performance. A trapeze harness is worn, allowing the sailor to be attached to a wire on the mast via a metal hook and hang off the edge of the boat, effectively increasing the moment arm to counter the moment generated by the wind on the sails (see Figure 1). .( !. Anecdotal evidence of low back pain amongst trapeze sailors is well recognised in the sailing community, however there is a paucity of research in the area. Marchetti et al.

  • Marshall Sandpiper Class Association Rules
    MARSHALL SANDPIPER CLASS ASSOCIATION RULES Initiated: December 18, 2012 Amended: April 1, 2014 1. INTRODUCTION It is the desire of these rules to “even the playing field” by identifying the easily measured major elements that contribute to boat speed, and limit them in such a way that each boat coming to the starting line, if adequately prepared, has a fair chance of winning. These “Rules” are in no way an attempt to make all catboats “absolutely identical”, an impossible task requiring extensive and burdensome restrictions that would be un-enforceable. These rules will be constantly monitored and updated as necessary to continue to provide a framework that allows both the veteran and the novice skipper a fair chance and satisfying experience sailing the Sandpiper in competition. 2. SAFETY All Sandpiper catboats shall comply with the following safety requirements: US SAILING prescribes that every boat shall carry life-saving equipment conforming to government regulations that apply in the racing area. All life vests shall be in good repair and shall be an appropriate size for each crew member. All Federal safety and registration requirements must be met before each catboat is allowed to participate in any Sandpiper event. Additionally all state safety and registration requirements must be met for the state in which the Sandpiper participates in the most class racing and events, with appropriate display of numbers and/or stickers if required. A functioning whistle or air horn shall be on-board. A tow-line at least 30 feet in length with a diameter of at least 3/8” shall be on-board.
