1. Have the Intermediate Swimming Honor.
Answers to the Intermediate Swimming honor can be found in the Recreation chapter of this wikibook.
2. Know the "rules of the road" for boating.
For the purposes of the sailing honor we will focus in the rules of the road that apply to small sailing boats.
It is important to note here that you are responsible for learning the rules and regulations that apply to whichever boat you are operating in the country and state or province where you are operating the boat.
There are five basic rules of the road for small sailing boats to decide who has the "Right-of-Way" so that each boat's skipper (driver) will know what to do to avoid a collision.
When sailing the words "left" and "right" in reference are replaced with "port" and "starboard". It is important to remember which is which since the rules of the road for sailing rely on using these words to assign right-of-way.
You might be able to remember this by noticing that the letter "R" appears twice in the word "starboard", and only once in "port". Then since "right" begins with "R", you will know that the right hand side of the boat when facing forward is the starboard side.
The next item to remember is the word "tack" and how it is used to describe which side of the boat the wind is blowing from. As seen in the illustration below, if the wind is coming from the right hand side of the boat, and the sail is on the left side, the boat is on a starboard tack. When the wind and sail are reveresed, the boat is on a port tack.
Rule Number 1:
When two sailboats are approaching each other and are on different tacks, the boat on the starboard tack has the right-of-way over the boat which is in the port tack. An easy way to remember this is to think about power boat lights. At the front the boat has red on the port (left side) and green to the starboard (right). If you are approaching a boat and can "see" the red light, then the other boat has the right of way. (small sail boats rarely have the actual lights, but you can imagine them)
In the illustration below, boat "A" on the port tack, must turn to avoid boat "B" on the starboard tack.
Rule Number 2:
When two sailboats are approaching each other and are on the same tack, the leeward boat has the right-of-way over the windward boat. Another way to say this is to say that the boat closer to the wind source must keep clear. The boat further from the wind source has the right-of-way.
In the illustration below, boat "B" is the windward boat and must turn to avoid boat "A" which is leeward.
Rule Number 3
A sailboat that is staying on a tack has the right-of-way over a sailboat that is tacking or gybing. A simpler way to say this is to say "make sure you have room to complete a tack or a gybe without interfering with any other boats before doing so". Make sure that you can see clearly in all directions to ensure you have room.
In the illustration below, boat "A" must ensure that it leaves plenty of room to avoid boat "B", who has the right-of-way, since boat "B" is continuing on its tack. However, in the event that boat "A" was unable to tack due to the proximity of "B", remember that "A" is the leeward boat so therefore could tell boat "B" to give room to tack, but would lose this right of way as soon as they actually began to tack.
Rule Number 4
Any sailboat that is overtaking a slower boat from behind must steer clear of the slower boat and give right-of-way. The slower boat should hold its course and allow the faster boat to pass.
In the illustration below, boat "A" is a faster boat, and must steer around the slower boat "B", who should remain on the same course.
Rule Number 5
Most of the time sailboats have the right-of-way over power boats. Since most powerboats are more easily maneuverable than sailboats, they must steer clear. This is not always the case however. Larger power boats are sometimes steering in the deep channel of the area, and cannot leave the channel. In this case the sailboat does not have right-of-way, and must avoid impeding the progress of the larger vessel. Many larger power boats cannot simply stop quickly or easily turn to avoid a small sailboat, so it is in the sailor's best interest to steer well clear of these larger boats.
In the illustration below, the powerboat "A" must turn to avoid the sailboat "B", who has the right-of-way.

- Cringle
- A grommet or metal ring in a sail though which a line is usually attached.
- Foot
- The bottom edge of a sail. The foot of the sail is between the clew and the tack.
- Grommet
- A stainless steel ring within the clew, tack, or head of the mainsail. Used to connect a control line. Also known as cringle.
- Head
- Top of the Sail.
- Jib
- The sail between the forestay and the mast. Also called the headsail. There are several sizes of Jibs.
- Leech (leach)
- The aft or back edge of the sail. Lies between the clew and the head.

10. Demonstrate the rescue of a person overboard.
Note: This requirement should be done under the supervision of an adult, with a rescue boat, to give assistance if needed.
11. Demonstrate what to do when a sailboat capsizes.
Note: This requirement should be done under the supervision of an adult, with a rescue boat, to give assistance if needed.
Capsizing is when your boat turns over (some say when the mast is in the water). A capsized boat may be either floating with the mast and sail lying on the water, or may have "turned turtle" lying with the mast pointing downwards. Some sailing schools tie a tether ball or flotation item to the top of the mast, so if a student capsizes the boat cannot turn turle. This is a good idea for beginner sailors.
A keel boat with a water tight or self draining cockpit normally rights herself because of the weight of the ballast keel. A small boat on the other hand has to be righted by the crew and there are a couple of methods.
Capsizing isn't scary or dangerous on a fair-weather day if you know how to swim. This is the main reason for the swimming requirement before taking the sailing honour.
Capsizing usually results from heeling to far or an accidental jibe. If you feel your in real danger of tipping over, luff the main sail at once (which is to let out the main sheet to allow the air to flow out of the sail). If your boat does go over on its side, stay with it, never swim away. You must do several things quickly.
Capsized boat.
Solo method
Stand on the center board
As quickly as possible stand on the center board (dagger board) to prevent the boat from turning completely upside down.
Free the sheets
Make sure that the main sheet (line that controls the main sail) is free and not secured tight in any way. Also if the boat has a jib sail, free the jib sheet as well. This will help the sails not fill with water when capsized, and not fill with air as soon as the boat is righted.
Point boat into the wind
If possible, get back into the water and position the boat so that the bow (front) is facing the wind. This will help your righting efforts, by not having to pull the sails up against a wind.
Lean and right the boat
Get back on the center board, and holding on the gunwale or the shrouds, lean back with all of your weight. This leverage should slowly bring the boat back to an upright position.
Get back in
Hang onto the boat as it rights, and crawl or slither back in over the side. The boat will probably be pretty low in the water since the cockpit will be close to full of water.
Bail and organize
Once upright and on board, take some time to bail out some water, untangle lines, and sort out any loose items before getting underway again.
On a calm day, in a protected area and with supervision, capsize your boat and right it several times to get confidence. You will be surprised how easy it will become with a little experience
With a crew "Scoop" method
Check all people
Make sure that no one is trapped under the boat or tangled in the rigging. if they are, help them to get free.
Stand on the center board / support mast
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.
Point boat into the wind
If possible, position the boat so that the bow (front) is facing the wind. This will help your righting efforts, by not having to pull the sails up against a wind.
Right the boat and scoop
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.
The sailor in the water is scooped into the cockpit and helps stabilize the boat as it is righted.
Entering the cockpit
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 re-capsize the boat while it is righting.
Get back in
Sailor still in the water will crawl or slither back in over the side. The boat will probably be pretty low in the water since the cockpit will be close to full of water.
Bail and organize
Once upright and on board, take some time to bail out some water, untangle lines, and sort out any loose items before getting underway again.
Remember the following safety rules
- Never swim toward shore. It looks closer than you think and you may not make it.
- Always stay with the boat.
- Do not swim under the sails or hull.
- Upon entering the boat after it has come upright, be sure to duck to avoid the swinging boom.
Additional information
Boat flotation
All sailboats can capsize and without adequate flotation they will sink. There should be enough flotation so when the boat is righted it will float high enough to keep it from being swamped with water and allow you to bail it out. Many manufactured boats have built-in watertight flotation compartments. The watertight integrity of these compartments should be inspected before you go sailing. They usually have access holes to allow you to check for leaks and remove any water that may have accumulated.
These holes may be small drain holes or large enough to pass your hand through them. Whatever size they are, it is critical that the drain plugs or access covers are securely fastened. If your boat capsizes and the holes are open, water flooding the compartments will deplete their flotation. Air bags or foam in or under the seats may also be used if a boat does not have watertight flotation compartments or the size of the compartments doesn’t provide sufficient flotation.
It is important for small boat sailors to know if their boat has sufficient flotation. One sure method of determining this is to capsize it in water that is deep enough for the boat, but shallow enough for you stand. Push down on one side until the boat starts to take on water, and then hand over hand up the shroud to the top of the mast to pull the mast down to the water. After the boat is capsized on its side, bring it upright again. How high does the boat float? How much water is in the cockpit? How long does it take to bail out the water? It shouldn’t take longer than several minutes.
Bailing equipment
Bailing equipment is also part of standard safety gear. While few small boat sailors carry a pump, a small bucket or a large plastic bottle with the bottom cut off works well. Attach the bailer to the boat with a length of cord to prevent it from floating away during a capsize. A large sponge (the kind used to wash cars) can be used to finish the bailing.
Above all, remember to stay with your boat. As long as its floating you will be safe. Remember the boat does not get tired and it can be visible a long way off. Don't ever think of swimming ashore.
