Wind
Leeward: Where the wind isgoing toWindward: Where the wind iscoming from
Luffing
The flapping of a sail when it isnot trimmed properly or theboat is pointed into or too closeto the wind
Irons
Pointed into the wind andstalled
Docking
1. Choose the side lined up withThe wind2. Approach from the downwind end3. Release the sheets so the sail can luff.
Boarding1. Pull the boat alongside the dock2. Crew to hold the boat steady3. Do not board over the bow – board at the middle of the hull. Step into the cockpit – not on the deck with feet pointing toward the bow4. Once aboard crouch to lower your center of gravity5. If able to lower the centerboard6. Load gear7. Load other passengers
Underway
Ready to get underway?
Look around and have a crewmate or dockhand push the boat away from the dock and into the wind
SteerTo turn starboard move tiller to port
To turn to port turn tiller to starboard
Points of SailDirection of sail inrelation to the wind
Wind: The wind is what powers a sailboat. Both the direction and strength of wind is important in setting the sails and maintaining control of the boat. True-wind direction is different from apparent-wind direction. The true-wind is the direction of the wind which makes the waves. The true-wind is perpendicular to the waves. The apparent-wind sails the boat. When the speed of the boat and the velocity of the wind are close, the difference between the apparent and true-wind is the greatest. The apparent wind is forward of the true-wind, except when sailing directly into or away from the true-wind. As one sails faster, the apparent-wind is drawn further forward. When sailing with the wind the apparent-wind has less of a force that the true-wind. When sailing against the wind, i.e., in a close reach, the apparent-wind has a greater force than the true wind.In general, the closer you sail to the wind, the closer the sails are pulled or trimmed to the midline of the boat. As you sail away from the wind, the sails are progressively let out. The exact position of the sails are based upon the direction and speed of the apparent-wind. (The direction of the apparent-wind is determined by the sailboat's tack [or relationship to the true-wind] and the relationship of the speed of the true-wind to the speed of the boat.) For the beginner sailor, it is easy to remember the five basic directions of sail ( point-of-sail ) each of which has its distinct characteristics of speed, heel and sail position.

Close Reach: Sailing with the front of theboat approximately 60 Deg off the windClose Hauled: Sailing as close to thewind as possibleBeam Reach:Broad Reach: Sailing far away from the windbut still able to fill the mainsail and jib onthe same side of the boatRunning: Sail directly downwind
Safety Position
1. Put boat on a close reach and luff the sails2. Boat will coast to a stop and drift3. Simply trim the sail to get underway again

Rules of the RoadWhen two sailboats on opposite tacks meet, the one on the starboard tack is the“stand-on” vessel and has the right-of-way.
Rules of the RoadWhen two sailboats on the same tackMeet the one on the leeward (downwind)side is the stand-on vessel and has theright-of-way
Rules of the Road
When a faster moving sailboatovertakes another from behind,it is the give-way vessel and mustKeep clear of the boat it is overtaking.
Rules of the Road
Powerboats keep clear of sailboatsSailboats keep clear of muscle-powered boats
Exceptions:1. All keep clear of disabled boats other then to give aid2. All boats give way to boats with limited maneuvering –barges, fishing, etc…3. In a channel yield to bigger boats4. Sailboat using an engine is a “powerboat”
Be Defensive.
CapsizeA sailboat capsizes when it heels over so far that the top of the mast touches the water.
Reasons:1.The sails are trimmed in too far2.The wind is too strong3.The boat is carrying too much sail4.The crew members do not use their weight correctly to balance the hull
CapsizeA small boat is said to capsize when it rolls over upside down or on its side with its mast and sails in the water. Turtling is a type of capsizing but only refers to the turning of the boat completely upside down with its sails and mast pointing vertically toward the sea bottom. Capsizes usually occur when a sudden gust of wind catches the skipper and crew off guard. For this reason, one should always have control of the main sheet to quickly let out and depower the mainsail.
Remember the following safety rules:#1. Never swim toward shore. It looks closer than you think and you may not make it.#2. Always stay with the boat.#3. Do not swim under the sails or hull. #4. Upon entering the boat after it has come upright, be sure to duck to avoid the swinging boom.
Capsize1. Count Heads – account for everyone2. Stay with the boat3. Release all the sheets from their cleats4. Turn the hull into the wind5. Swim to the centerboard6. Pull down on the board to right the boat7. Grab the hull before it drifts away8. Climb on board from the stern
CapsizeThere are several methods of righting a capsized boat. The Scoop Recovery Method can be used for righting a boat when sailed by two or more people. The boat often capsizes toward the leeward side and both the skipper and the crew end up in the water. One sailor supports the mast to keep the boat from turtling. The other sailor maneuvers around the boat (not under the hull) and climbs on the centerboard. The sailor in the water grabs on to a stationary object in the boat's cockpit. The sailor on the centerboard leans back and starts to right the boat. If more righting leverage is needed, a jib sheet may be used to lean farther out on the centerboard. The sailor in the water is scooped into the cockpit and helps stabilize the boat as it is righted. As the sailors enter the cockpit they should duck to avoid getting hit by the boom. The sheet of the mainsail and jib should be loose and the sails allowed to luff so they will not recapsize the boat while it is righting.

Capsize – Walk-OverIn the Walkover Method of recovery a sailor quickly swings over the side of the boat onto the centerboard before the boat starts to capsize. He can then lean backwards and as the boat rights itself he can quickly get back into the cockpit.

Running Aground
If you hit rocks the bottom may be damaged. If you hit mud or sand you may be
stuck and need to shove off.Don’t get out unless you have to. If you do get out maintain control
of the boatholding it forward of the mast to keep it pointed into the wind and
the sailsluffing.
1. Release all sheets to luff the sails2. Turn into the wind and then to deep water3. Raise the rudder and centerboard 4. Push off (if necessary using an oar or pole)5. As you enter deep water lower the fins to resume sailing
Maintenance
Keep the boat clean.Rinse and wipe to clean dirt, debris or footprintsPump, bail, drain or sponge-dry the hullSecure all rigging by pulling it taut and cleatingCoil longer linesStow or remove loose gearDry out and roll or furl the sailsRinse off saltwater well – especially metal or moving partsSecure boat and sail covers
