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. -
The Safety Position Is a Standard Basic Small Boat Sailing Technique
SAFETY POSITION Paul Tara, 2014 Definition: The Safety Position is a standard basic small boat sailing technique. It occurs when a boat is borne off onto a close reach, stopped or moving slowly, with the sail eased and luffing. The Safety Position is used to minimize speed while maintaining control. Physics: In the Safety Position, the boat is more or less in equilibrium. Because she is on a close reach, she is out of the “no go zone” where control decreases. Easing the sail reduces speed and heeling force. It also moves the center of effort of the sail plan forward, decreasing weather helm. Control is maintained because the boat is almost stopped, but still in balance, requiring only very small changes in rudder angle and sheet tension to maintain the same relative wind angle. The Safety Position is not, as many believe, when a boat is luffing, headed straight upwind. Such a boat is in disequilibrium. It will eventually stop. Then it will begin making sternway, often with unpredictable consequences. Guidelines: • Beginners are often told to “let go of everything” if things get out of control. This may avert an initial capsize but is not “safe”, especially in close quarters. The boat will immediately go into a series of uncontrolled round-ups and accidental tacks. • After a near capsize, or whenever needing to maximize control, the boat should be deliberately steered onto a close reach and the sail eased until it is luffing. • In breeze, ease the vang and raise the board halfway. This will help the boat settle down. -
Mainsail Trim Pointers, Reefing and Sail Care for the Beneteau Oceanis Series
Neil Pryde Sails International 1681 Barnum Avenue Stratford, CT 06614 203-375-2626 [email protected] INTERNATIONAL DESIGN AND TECHNICAL OFFICE Mainsail Trim Pointers, Reefing and Sail Care for the Beneteau Oceanis Series The following points on mainsail trim apply both to the Furling and Classic mainsails we produce for Beneteau USA and the Oceanis Line of boats. In sailing the boats we can offer these general ideas and observations that will apply to the 311’s through to the newest B49. Mainsail trim falls into two categories, upwind and downwind. MAINSAIL TRIM: The following points on mainsail trim apply both to the Furling and Classic mainsail, as the concepts are the same. Mainsail trim falls into two categories, upwind and downwind. Upwind 1. Upwind in up to about 8 knots true wind the traveler can be brought to weather of centerline. This ensures that the boom will be close centerline and the leech of the sail in a powerful upwind mode. 2. The outhaul should be eased 2” / 50mm at the stopper, easing the foot of the mainsail away from the boom about 8”/200mm 3. Mainsheet tension should be tight enough to have the uppermost tell tail on the leech streaming aft about 50% of the time in the 7- 12 true wind range. For those with furling mainsails the action of furling and unfurling the sail can play havoc with keeping the telltales on the sail and you may need to replace them from time to time. Mainsail outhaul eased for light air upwind trim You will find that the upper tell tail will stall and fold over to the weather side of the sail about 50% of the time in 7-12 knots. -
Sail Trimming Guide for the Beneteau 37 September 2008

The following features are built into this headsail: • The genoa sheets in front of the spreaders and shrouds for optimal sheeting angle and upwind performance • The size is optimized to sheet correctly to the factory track when fully deployed and when reefed. • Reef ‘buffer’ patches are fitted at both head and tack, which are designed to distribute the loads on the sail when reefed. • Reefing marks located on the starboard side of the tack buffer patch provide a visual mark for setting up pre-determined reefing locations. These are located 508mm/1’-8” and 1040mm / 3’-5” aft of the tack. • A telltale ‘window’ at the leading edge of the sail located about 14% of the luff length above the tack of the sail and is designed to allow the helmsperson to easily see the wind flowing around the leading edge of the sail when sailing upwind and close-hauled. The tell-tales are red and green, so that one can quickly identify the leeward and weather telltales. -

Although these outcomes can be used to prevent, identify and minimise problems, Robotics as well as to drive multiple market sectors, the design and development of such platforms remains an open challenge. In particular, energy efficiency, control and robustness are major concerns with implications for autonomy and sustainability. Rigid wingsails allow autonomous boats to navigate with increased autonomy due to lower power consumption and increased robustness as a result of mechanically simpler control compared to traditional sails. These platforms are currently the subject of deep interest, but several important research problems remain open. In order to foster dissemination and identify future trends, this paper presents a survey of the latest developments in the field of rigid wing sailboats, describing the main academic and commercial solutions both in terms of hardware and software. -

An Autonomous Wing-Sailed Catamaran Ph.D.Thesis by Gabriel H. Elkaim the Wingsail Wingsail Description Wing Versus Sail
An Autonomous Wing-Sailed Catamaran Ph.D.Thesis by Gabriel H. Elkaim The following information has been extracted from the thesis submitted by Dr. Gabriel Elkaim to Stanford University, and for which he was awarded his Ph.D. The full thesis, which can be viewed at http://www.soe.ucsc.edu/~elkaim/Documents/GabrielElkaimThesis01.pdf (and an extract published in the AYRS’s Journal ‘Catalyst’ which can be found at http://www.soe.ucsc.edu/~elkaim/Documents/Catalyst_BoatArticle.pdf), describes the Atlantis project, whose aim was the design, development, and experimental testing of an autonomous wind- propelled marine craft. The parts printed here are the ones which may be of interest to members of the JRA These extracts are re-published from the AYRS Journal “Catalyst” by kind permission of Dr. Gabriel and of the Amateur Yacht Research Society. Please note that the figures are numbered as in the original document. The Wingsail The most visibly unique aspect of the Atlantis project is the wingsail propulsion system, as shown in Figure 5-1. The design considerations and goals are: equivalent performance to the original sail system, low actuation force, and the ability to precisely control the resulting system. A sloop rig sail can achieve a maximum lift coefficient of 0.8 if the jib and sail are perfectly trimmed. Realistically, an operating maximum lift coefficient is 0.6. The design goal of the Atlantis wing is to achieve a maximum lift coefficient of 1.8. Since this allows the wing to generate three times the force of an equivalently sized sail, the wing area is reduced to one third of the area of the original sails. -

FURTHERDEVELS'NENT OF THETUNNY RIG E M H GIFFORDANO C PALNER Gi f ford and P art ners Carlton House Rlngwood Road Hoodl ands SouthamPton S04 2HT UK 360 1, lNTRODUCTION The idea of using a wing sail is not new, indeed the ancient junk rig is essentially a flat plate wing sail. The two essential characteristics are that the sail is stiffened so that ft does not flap in the wind and attached to the mast in an aerodynamically balanced way. These two features give several important advantages over so called 'soft sails' and have resulted in the junk rig being very successful on traditional craft. and modern short handed-cruising yachts. Unfortunately the standard junk rig is not every efficient in an aer odynamic sense, due to the presence of the mast beside the sai 1 and the flat shapewhich results from the numerousstiffening battens. The first of these problems can be overcomeby usi ng a double ski nned sail; effectively two junk sails, one on either side of the mast. This shields the mast from the airflow and improves efficiency, but it still leaves the problem of a flat sail. To obtain the maximumdrive from a sail it must be curved or cambered!, an effect which can produce over 5 more force than from a flat shape. Whilst the per'formanceadvantages of a cambered shape are obvious, the practical way of achieving it are far more elusive. One line of approach is to build the sail from ri gid componentswith articulated joints that allow the camberto be varied Ref 1!. -
