Badger Sloop A/B Instruction Outline 1 Badger Sloop A/B Instruction Outline Prelude Badger Sloops are a big departure from the Techs for many students in that the Skipper needs to supervise and direct the actions of a crew. To get a Badger Sloop Skipper rating it is imperative that the student demonstrates clear Skipper/Crew communication, critical thinking and problem solving skills. The sailing instructor facilitates the learning experience by providing sailing theory as well as constructive, timely feedback during the lesson. Stewardship Instructors and students need to take good care of the Badger Sloops. Hoofer’s calls this ‘Stewardship’. Hoofer instructors are the exemplars and will demonstrate proper care of the Badger Sloop at all times. If instructors don’t do it – neither will the students and our fleet will be trashed for no good reason. If an instructor observes non-stewardship they need to intervene immediately. Instructional Strategies A Badger Sloop A/B Class may have first time students or those that are on their 5th or 6th lesson. Repeat students have ‘heard it all before’ and may mentally check-out. Don’t let that happen. These students are trying to get their Skipper rating and should, by now, have read the Badger Sloop Manual and have a solid command of sailing theory. During the Sloop Theory section one can involve them by having them explain to the class (their crew) how to do a Man Overboard drill, back winding the jib when leaving the pier, etc. This is good practice for them to demonstrate communication skills and also lets the Hoofer’s Sailing Instructor observe and critiQue student skills. I. Introductions - instructor and student sailing experience 1. Boats sailed 2. # of Badger Sloop A/B lessons taken 3. Prior instructor feedback on what needs work II. Sloop Theory (Chalk Talk) I like to move through this rather quickly and then reference during on-water activities. 1. Similarities/Differences between Cat-Rigged and Sloop 2. Center(s) of Effort and Center of Lateral Resistance Brian A. Adams June 3, 2010 2 3. Lee Helm and Weather Helm 4. Jib to back wind (hold jib towards shore) i. Always do this to maintain safe take-off ii. Back winding is a great example of Lee helm! 5. Coming About – Skipper/Crew Responsibilities 6. Jibing – Skipper /Crew Responsibilities 7. Man Overboard Drill – Figure Eight Approach III. Rigging The Badger Sloop Have students on their 3rd or more lesson lead the rigging and explain to other students what and why they are doing with the rigging. Instructor should see if class can ‘think through’ any issues and then offer feedback on what went well or raise Questions about how they might rig in other conditions. 1. Sign-out the Badger Sloop using the Hull # 2. Get Jib and Main from sail area 3. Plug, Main Sail, Jib 4. Adjust Outhaul, Vang, Jib Cars for the wind speed i. Jib Cars towards mast for light wind/out for heavy ii. Outhaul tight for light or heavy winds! iii. Always secure Jib with life jacket so as to not trash the Jib iv. In heavier wind, secure mainsail using mainsheet to protect sail v. Check halyards and sheets to make sure they are clear and not wrapped around mast or twisted wrong way. 5. Extras for the boat – do this now so you don’t forget i. Throwable ii. Two Paddles iii. Return the Main and Jib Sail cover bags to the sail area IV. Securing the Badger Sloop to the Trolley. 1. Check Trolley first for proper rail alignment – rear rail critical! 2. With student on side of front and rear bunks, roll Quickly with Eric Cartman-esQue ‘Author-i-tai!’ 3. Use knots on either side that will not slip! (1/2 hitches or some variation) Brian A. Adams June 3, 2010 3 V. Getting the Sloop in to the Water 1. Safety and Stewardship – have at least one student use a paddle to fend-off the boat prior to launching! Feet and toes get crushed when waves lift hull up and down. Paddles save boats and student limbs. And that’s a good thing. 2. Hand Signals – Up/Down/Hold 3. Lower Sloop until front bunk of cart is half submerged 4. Students move boat along pier using paddle(s) to fend-off. 5. Move to the farthest point-out on the leeward side of pier. Use paddles again to help get From one side oF the pier to the other. VI. Rigging at the Pier 1. Raise the Mainsail 2. Adjust Vang and Outhaul for conditions. 3. Get most of the class into the Badger Sloop 4. Raise the Jib 5. Carefully – Lower the Centerboard. Do not let it slam down as this will damage the sloop! 6. All Crew Aboard VII. Leaving the Pier 1. Designated Skipper is at helm and tells crew what they are going to do and what heading they will be taking-out onto the lake. 2. Skipper assigns crewmate to backwind the jib (towards shore!) 3. Instructor casts-off and steps onto Sloop Bow Deck and provides feedback during the take-off maneuver. 4. Jib is Backwinded 5. Sloops successfully sails out of Mooring Field VIII. Upwind Sailing Brian A. Adams June 3, 2010 4 During this activity rotate students so they each have a turn doing 4-5 tacks (coming about) and offer feedback. It’s also a good time to elaborate on the Chalk Talk and discuss the role of the jib and crew responsibilities. 1. Tacks should be clean and smooth – not jerky like in a tech 2. Tiller Extension used at all times 3. Ready About/Ready/Hard-a-lee or Helms-a-lee commands 4. Continue discussion from Chalk Talk about the Center(s) of Effort and Center of Lateral Resistance. 5. Ask class what can be done to increase/decrease Lee and Weather Helm. Why might they do that? What’s the big deal and why does it matter? 6. Optimizing the Jib and Main: What do telltales tells us? IX. Man Overboard Drill Students are rotated through the skipper position and attempt 4 to 5 Man Overboard ‘Rescues’ of the Throwable. The figure eight maneuver is the textbook example we teach, but should they always use this approach? Engage the class in a discussion about this and have them think through as a group what is the safest and Quickest way to retrieve the Throwable. 1. Instructor chucks Throwable and yells ‘Man Overboard!’ 2. Skipper assigns a spotter 3. Spotter yells-out Throwable position and # of boat lengths using the Bow as 12 O’clock. 4. Skipper executes come about after 3-6 boat lengths 5. Skipper commands crew to release or blow the jib 6. Skipper sails in Irons towards Throwable, keeping tiller amidships the whole time. Note: Skipper needs to make sure that they mainsail is completely depowered. Check mainsail aft oF sidestays to see iF it is catching wind. 7. Badger Sloops comes to a halt downwind (leeward) of the Throwable. 8. Crew retrieves Throwable using both hands as though they were lifting the tops of a lifejacket. X. Downwind Sailing Uncontrolled jibes or accidental jibes are dangerous to the crew and the boats. During this activity the instructor should demonstrate a controlled jibe and then have each student do 4 to Brian A. Adams June 3, 2010 5 controlled jibes. Students should have reviewed this in the Badger Sloop Manual. If they haven’t, ask ‘Why not?’ 1. Skipper clearly communicates ‘Prepare to Jibe’, waits to hear ‘Ready’ and yells ‘Jibe-Ho!’ 2. Jibe should be smooth and non-violent. Note: Sail should never swing all the way into the opposite sidestay. This will damage the sail and the boat. 3. Time and weather permitting, demonstrate Wing-on-Wing with Jib and Main. XI. Pier Landings & Take-ofFs Landings should be done like a pro! Sculling or crashing hard into the pier is unacceptable. If a boat pulls-up short or is coming in to fast, student should sail away and attempt another landing. For this reason we teach a close-hauled landing so that the boat is always powered-up until the skipper commits to the final in irons landing. Like the other activities, rotate students so that they get multiple opportunities to practice landings – and takeoffs! XII. De-rigging at the Pier. 1. Centerboard is slowly raised all the way up and cleated-ofF. IF the centerboard is not all the way up it will strike the decking when putting away. 2. Jib is lowered and secured with a lifejacket 3. Mainsail lowered with boom inside of boat 4. Boom, sail and all lines are inside of boat. Note: Mainsail can be secured with mainsheet to prevent it from falling in water. XIII. Preparing the Trolley 1. Badger Sloop cradle is placed ‘deep V’ away from the lake on the trolley. 2. Tie the cart down on the side closest to the pier first. Half-hitches 3. Tie the cart down on the other side. 4. Lower the cart into the water until the front bunk is half submerged Brian A. Adams June 3, 2010 6 XIV. Getting the Sloop onto the Cart and back on Shore. Stewardship! If Sloop is not properly positioned on cradle or the cart is not secured to trolley damage to the Sloop will occur. 1. Student Holds Painter while other fends-off with paddle. 2. Slide Badger Sloop until the mast is just slightly behind the front bunk. 3. Using Up hand signal, winch operator raises boat slightly.

    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.

  • 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.

  • 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.

    CSC DINGHY SAILING MANUAL February 2021 Introduction There's no substitute for actual sailing if you want to learn to sail. This booklet is only intended as a technical reference, to reinforce sailing lessons. If you're new to sailing, relax—you're in good company. Most new members of the Cal Sailing Club do not know how to sail when they join. Put this book down until later, and go sailing. Credits Editor: John Bongiovani Author: John Bergmann Change History Anonymous. First published Edition. The club began about a century ago as an offshoot of a loose association of UC students and professors who were interested in sailing. Perhaps there was a manual—who knows? A manual for sailing was put together using a typewriter and hand drawn pictures, distributed in booklet format. The most memorable part was a cartoon telling how to get onto a Lido from the water, showing a shark. Fitting conveniently in a pocket, most copies were turned into pulp during the new owner's first lesson. Sometime in the 1970s. Various minor changes stemming from disputes over gybing and other pettifoggery. Sometime during the disco era. The advent of the computer in revising the manual, but keeping the same organization. Major discovery: pdf's don't fit in pockets. Sometime in the Clinton era. Major revisions to reflect the end of the Lido, which had served the club (poorly) since 1959. Sometime in the Bush II years V11. Joel Brandt June, 2011 Dinghy Manual. Cal Sailing Club February 2021 Page 2 V12 John Bergmann, updated content and format, added detail on the RS Ventures, March, 2016 V13 Made corrections, added content on Quests, added more figures, and added a table of figures.

[email protected], [email protected], [email protected] , [email protected] May 9, 2018 Abstract This paper presents the extensive review on modelling and control of non linear autonomous sailboat system us- ing Conventional PID controller (CPID) and PID controller with Particle swarm optimization technique (PSO).A large heeling angle, a lot of rolling motion due to wind rush can cause the boat to capsize. Sailboats cannot move in the up- wind direction so one has to move in a zigzag pattern to sail in the up-wind direction. This mainly focuses on the way of lively controlling the sail angle and rudder angleof the sail- boat to reduce the heeling angle and rolling motion caused by the wind. The sail angle is optimized and rudder angle is controlled for the given wind direction and desired moment. The main object is to allow long permanence autonomous mission. Key Words:Sailboat, sail angle, rudder angle. 1 International Journal of Pure and Applied Mathematics Special Issue 1 Introduction Sailboat played an important role for mankind. Sailboats were mainly used for fishing, trading, and transportation etc.Now a days priority of sailors moved from transportation to sport or vacation.
