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. -
Sail Trimming Guide for the Beneteau 37 September 2008
INTERNATIONAL DESIGN AND TECHNICAL OFFICE Sail Trimming Guide for the Beneteau 37 September 2008 © Neil Pryde Sails International 1681 Barnum Avenue Stratford, CONN 06614 Phone: 203-375-2626 • Fax: 203-375-2627 Email: [email protected] Web: www.neilprydesails.com All material herein Copyright 2007-2008 Neil Pryde Sails International All Rights Reserved HEADSAIL OVERVIEW: The Beneteau 37 built in the USA and supplied with Neil Pryde Sails is equipped with a 105% non-overlapping headsail that is 337sf / 31.3m2 in area and is fitted to a Profurl C320 furling unit. 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. -
The Weather Helm Issue (Rev 20 02 2020)
Corbin 39 – the weather helm issue (rev 20 02 2020) Synopsis The subject of weather helm comes up repeatedly when discussing the Corbin 39 and not all of the folklore is justified. This note attempts to summarise the issue and to relate it to sufficient evidence, and to qualitative theory, that we can be reasonably certain of the situation. Remember - It is possible to overpower a yacht and induce weather helm, what we are trying to do is identify excessive weather helm. The key take-away is that the excessive weather helm was a genuine issue, which affected all the mk1 cutters irrespective of whether they were equipped with the taller double-spreader mast or the shorter single-spreader mast, provided that the mast was set in the intended aft mast position. Perhaps this was worse in the mk1 tallmast vs the mk1 shortmast, but we are not at all certain of that. All the mk1’s that had the forestay relocated onto a 3-foot long bowsprit were later able to alleviate this to an extent. The mk 1’s that have reduced the area of their main by shortening the mainsail boom & foot (or used in-mast furling) have reportedly completely eliminated this weather helm. All other versions including the mk1 ketches and all the mk2 cutters & ketches appear to be completely unaffected. This is the first openly published version of this analysis. Previous drafts were incomplete and drew erroneous conclusions in some areas due to an absence of reliable data. That has now been overcome as further evidence has come forwards, and so there are material differences between this version and previous drafts. -

What's in a Name?
Neil Pryde Sails International 354 Woodmont Road #18 Milford, CT 06460 203-874-6984 [email protected] Adjusting and Trimming Your Roller Furling Headsail A layman’s guide to getting the most from your headsail By Bob Pattison Most contemporary mid-size sailboats built in North America over the last twenty years have been, by and large, masthead sloops with one or two sets of spreaders and fly a headsail that is between 140% and 155% in size. Generally these headsails are set flying on roller furling gear. With this in mind, here’s an easy and straightforward approach to trimming roller furling headsails and setting them up for quick and precise reefing. )LUVW7KLQJV)LUVW+DO\DUG7HQVLRQ)LUVW7KLQJV)LUVW+DO\DUG7HQVLRQ Luff tension is used to remove wrinkles from the luff of the genoa, so that the sail is smooth from to tack to head along the luff. Increasing the What’s in a Name? luff tension beyond this amount will affect the overall shape of the sail Headsail size percentages refer to length of by inducing stretch along the luff, which will pull the draft (shape) of the the “luff perpendicular’ or L.P. This is an imaginary line that runs from the clew of the sail forward for a better shape in heavier wind conditions. Don’t do it (!), sail and intersects the luff at a right angle, as you will more than likely, furl the sail as the wind strength increases the length of which is relative to the “J” negating the need for additional luff tension. -

420 Tuning Hints
420 Tuning suggestions College of Charleston 2012 Boat Setup on land: 1) Before sailing check that your shroud pin/ring dings are taped and secure, your tiller extension universal is solid, there’s no wiggle in your pintles and your hiking straps knots secure. 2) Tie your main halyard to the head of your main with a figure eight through the headboard grommet and then a half hitch back around the halyard. (see picture) 3) Hoist your jib and tension the rig tightly by placing a foot on the bow and pulling on the head stay while your team mate tensions the jib halyard. Don’t be afraid to over tension at this point as you’ll double check and most likely reset the tension once on the water. It’s easier to loosen once sailing than to tighten it! 4) Hoist your main and tension the halyard tightly. Use the 2:1 purchase to sock it up tight to the top of the mast. Again, it’s much easier to set it up tight on the dock than to rehoist once sailing! Set up on the water, before the start: 1) Trim your sails and head upwind. 2) Watch/study your leeward shroud as it is your guide to proper rig tension (through jib halyard tension). 3) Ideally the leeward shroud will just start to slacken to the point a slight wiggle (not more than ½”) is visible when the main is sheeted to maximum trim for the breeze/conditions at that time. Note: The advantage of using the “leeward shroud wiggle” is that you can gauge the amount of tension based on a given condition. -
For Session B Set One of the Two Buoys to Wind- Ward to Facilitate an Easy Beat and a Broad Reach Return Between Them
For session B set one of the two buoys to wind- ward to facilitate an easy beat and a broad reach return between them. Draw the circle on the white board to demon- strate the wind direction, the no sail zone, the need to sail to windward, and the sail set to the wind, and leeway. Explain that the boat will slip sideways when sail- ing to windward resulting in the straight line beat to the buoy being some- times unattainable. If there are windshifts a tack may therefore be necessary. In session B the instruc- tor is constantly reinforc- ing the concept that to windward the sail is set, the course adjusted to suit the wind direction. 7. Beating Continued… 7. We say pushing it back on course, as the boat will always be try- ing to point up into the wind and you hold a course by pushing down- wind on the joystick. This is the correct balance for a sailing boat and called "WEATHER HELM" - the boat wants to turn up into the weather. "LEE HELM" is when it wants to turn downwind. Reefing 1. Reeng is reducing the power generated by the sail. 2. Reeng is often necessary in strong winds and on our boats it is accomplished by pulling a cord which rotates the mast, rolling up the sail like a blind. 3. To reef, the port side (left side) reeng line is pulled with the left hand and is jammed in the clamcleat positioned on the console by your left knee. 4. The rst turn of the mast attens the sail which greatly reduces its power with little reduction in area. -

WINDSURFING I MANUAL www.recreation.ucla.edu/mac Windsurfing 2 INTRODUCTION www.recreation.ucla.edu/mac Windsurfing 3 We would like to share with you the physical and mental challenge of windsurfing, the exhilaration of weather, equipment and windsurfing with friends. GOALS Our beginning classes are designed for the complete novice with gentle wind, shallow water, equipment appropriate for beginners and lots of personal feedback. This may not challenge those who have windsurfed before, but it is an opportunity to correct improper technique before it becomes habitual. You can also arrange a brief private lesson, demonstrate your skill, rent our equipment and join our quest for wind and water. In Windsurfing I you will: • Have fun sailing in a light breeze (4-7 mph) • Learn to rig beginner equipment, uphaul, get underway, tack and care for equipment • Qualify to rent beginning equipment by bearing to a point upwind, returning on a run, tacking and jibing at will and passing a written test on sailing theory, right of way, parts of the rig, and basic safety considerations. You will probably benefit from additional time on the water before you tackle the more challenging conditions in our Windsurfing II class. One way to practice the skills you learn in beginning classes is to rent equipment from the dock on a thursday or friday. You will get more from Windsurfing II class if the basics have become automatic. When your arms start to get tired before the rest of you does, you will be ready (and motivated) to learn how to use a harness! In Windsurfing II you will: • Have fun trying out intermediate equipment. -
Flying Scot Tuning Guide and Tips
Flying Scot Tuning Guide and Tips Pre-Race Sail Adjustments Mainsail Mast Rake – 28’ 6” Halyard – better too loose than too tight. Raise until luff is smooth and then ease back until small wrinkles appear. Outhaul – better too tight than too loose. Very hard crease in heavy air; tight crease in medium conditions; loose crease in light air and in sloppy waves. Note: Opinions vary, but I don’t believe you need to ease the outhaul when going downwind. Reason: more outhaul = more projected sail area. Cunningham – nothing unless you are overpowered in heavy air. In heavy air, raise your main all the way up until the luff is smooth (but don’t overtighten and break your halyard shive!) and then crank on the Cunningham hard to pull the draft forward as much as possible. JIB Rig tension – loose rig = no tension and approximately 1” of “slop” snug = 80-120 lbs tight = 120-180 lbs Halyard – slight “scallops” at hanks. (You must sail close-hauled to accurately check this.) Fairlead - move it aft in heavy air when overpowered; otherwise, all the way forward. SPINNAKER Halyard – tie knot 6 inches from head Guy -- under hook Sheet – NOT under hook Topping lift – at perpendicular height (Marked line = easy reference) Page 1 Flying Scot Tuning Guide and Tips During-Race Adjustments MAINSAIL Mainsheet: 1st gear = main batten out slightly; sailing “fat” w/slight heel to leeward 2nd gear = main batten parallel to boom; sailing flat 3rd gear = main batten SLIGHTLY hooked (can’t stay like this too long usually); jib luff is breaking (ie. -
