Sailing in Heavy Weather
SAILING IN HEAVY WEATHER John Jourdane As the wind increases you need to reduce sail area the keep the boat under control Why we need smaller sails as the wind builds Think of a weather vane Keep the helm balanced Pac Cup Rules – Heavy Air Sails 1. Mainsail – must be able to reduce luff length by 10% 2. Boat shall carry at least 2 of the following 3 sails: a. A trysail with sail numbers on both sides, which can be set independently of the boom, has an area less than 17.5% of E x P, and which is capable of being attached to the mast. Sails newer than 1/1/2014 must be constructed of highly visible material. b. A storm jib with an alternate means of attachment to the headstay, if the head foil fails, and highly visible material c. A heavy-weather jib of area not greater than 13.5% of the foretriangle squared. The North Pacific High As the wind increases Go to progressively smaller jibs Reef the mainsail Put more reefs in the main Put up the storm jib or storm staysail Deep-reefed main alone Storm trysail and storm jib or storm staysail Heave to with trysail and storm jib or storm staysail Storm trysail or storm staysail alone Reefed Main and Small Jib Storm Sails Should be purpose-built for your boat Need to be made from heavy material to withstand the beating a storm can produce Storm Jib Gale Sail Gale Sail Gale Sail Storm Staysail Storm Jib Stow the storm jib in it’s own bag in an easily accessible place. -

Wianno Senior Racing Guide I. Crew Page 2 II. Boat Setup Page 5 III. Sail Trim Page 9 IV. Quick Reference Page 14 Contact [email protected] with questions or comments. **pre-Doyle Mainsail (2013)** I. Crew: At the most basic, you cannot get around the racecourse without a crew. At the highest level of the sport where everyone has the best equipment, crew contribution is the deciding factor. Developing and maintaining an enthusiastic, competent, reliable, and compatible crew is therefore a key area of focus for the racer aspiring to excellent results. Prior to the Class Championship you should have your crew set up, with assigned positions and job responsibilities – well trained in tacking, jibing, roundings and starts. The following may help you set up your program to attract good crew. First, good sailors want to do well. So do everything you can to make sure that you understand how to make the boat go fast and do everything you can to ensure that your boat is in good racing condition (more on these two issues later). If you are a helmsman make sure that your driving skills are developed to your best abilities. Assemble sailors who are better than you or find an enthusiastic non-sailor to train and encourage. Arrange practice time either pre/post-race or on a non-racing day. The right type of crew personality will want to improve performance and the best way to do this is to spend time together in the boat. If your crew does not wish to make the effort to spend time in the boat, cast a wider net. -
Boom Vang Rigging
Congratulations! You purchased the best known and best built pocket cruising vessels available. We invite you to spend a few moments with the following pages to become better acquainted with your new West Wight Potter. If at any point we can assist you, please call 800 433 4080 Fair Winds International Marine Standing Rigging The mast is a 2” aluminum extrusion with a slot on the aft side to which the sail’s boltrope or mainsail slides (options item) enter when hoisting the main sail. Attached to the mast will be two side stays, called Shrouds, and a Forestay. These three stainless cables represent the standing rigging of the West Wight Potter 15. The attachment points for the shroud adjusters are on the side of the deck. Looking at the boat you will find ¼” U-Bolts mounted through the deck on either side of the boat and the adjuster goes over these U-Bolts. Once the shroud adjuster slides in, the clevis pin inserts through the adjuster and is held in place with a lock ring. When both side stays are in place we move onto the mast raising. Mast Raising First, remove the mast pin holding the mast base in the bow pulpit. Second, move the mast back towards the mast step on the cabin top of the boat and pin the mast base into the aft section of the mast step (the mast step is bolted onto the cabin top of the boat). The mast crutch on the transom of the boat will support the aft end of the mast. -

Paradox Sailing For
November 29, December 20, 2009 Paradoxes of Sailing John D. Norton Department of History and Philosophy of Science and Center for Philosophy of Science University of Pittsburgh www.pitt.edu/~jdnorton To appear in Sailing and Philosophy, Patrick A. Goold, Ed., in Philosophy for Everyone. Wiley-Blackwell. Paradoxes have long been a driving force in philosophy. They compel us to think more clearly about what we otherwise take for granted. In Antiquity, Zeno insisted that a runner could never complete the course because he’d first need to go half way, and then half way again; and so on indefinitely. Zeno also argued that matter could not be infinitely divisible, else it would be made of parts of no size at all. Even infinitely many nothings combined still measure nothing. These simple thoughts forced us to develop ever more careful and sophisticated accounts of space, time, motion, continuity and measure and modern versions of these paradoxes continue to vex us. This engine of paradox has continued to power us to this day. Relatively recently, Einstein fretted over a puzzle. How was it possible that all inertially moving observers would find the same speed for light? Surely if one of them was chasing rapidly after the light, that observer would find the light slowed. But Einstein’s investigations into electricity and magnetism assured him that the light would not slow. He resolved this paradox with one of the most influential conceptual analyses of the twentieth century. He imagined clocks, synchronized by light signals, and concluded that whether two events are judged simultaneous will depend upon the motion of the observer judging.1 1 For more, see Norton (forthcoming). -

Emergencies on the Water Types of Emergencies
NCSC Instruction EMERGENCIES ON THE WATER TYPES OF EMERGENCIES In-Irons Accidental Jibe Running Aground Sailing In Light Wind Sailing In Strong wind Capsize Swamped IN-IRONS More likely when wind is light. Determine if you are moving ahead or astern - watch for bubbles Steer boat onto a tack, you might have to sail backwards Back the jib When sails fill & you begin to move ahead, shift tiller hard over ACCIDENTAL JIBE Most likely to happen when sailing by the lee. Sailing by the lee - while running, when the wind crosses the center line and gets on the same side as the mainsail (the lee side) In this position, the wind can violently push the mainsail to the other side. The boom can hit someone and the sudden shift in weight can upset the boat. ACCIDENTAL JIBE To avoid an accidental jibe: Always know where the wind is Closely watch the sails & tell tales Have someone’s hand on the boom when running to tell if there is back pressure on the main ACCIDENTAL JIBE If you do accidentally jibe: Warn the crew to get low and centered Balance the boat - be ready to shift your weight quickly If you can, pull in the main. Then let it out gradually to soften the blow. Turn the bow a little into the wind on the new tack RUNNING AGROUND Quick action is needed! 1. Quickly come about, or bear off 2. Pull up the centerboard Crews should be instructed to do this without being told, but remind them. RUNNING AGROUND When did you say the tide was coming back in? RUNNING AGROUND You may not know you are aground.
