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.

- Drain and dry the boat. The first thing you should do when your boat is back on shore is to open the portholes and drain bungs. Always leave the boat with the drain bungs open and the portholes open, so the flotation tanks can dry out completely. Prop the boat up if needed to ensure the drain holes are the lowest point. You can place a piece of carpet on the ground under the transom, and raise the bow of the boat onto a sawhorse or support. Remember to close all drain holes before putting the boat back in the water.
- Organize your gear. Keep the hatches, drain bungs and other loose gear in one place, so you know they will always be there. After sailing, and after rinsing out or washing, and drying your sailing gear, put it back in a gear bag. It is frustrating to show up at the lake on a gorgeous day, only to discover that you left your sailing boots or some other piece of important gear, at home.
- Sail care. You can leave the mainsail on the boom, if you will be sailing the boat again soon. Roll up the main from the head, perpendicular to the luff, so that it ends up in a roll parallel to the boom. Also roll the jib up, put it inside the jib bag, and leave that in the boat. All sails should be removed from the boat if it is to be trailered or stored out of the water for any length of time. All sails should be dried and folded or rolled and placed in sail bags ready for the next launch.
- Centerboard care. Leaving the board resting on the trolley or trailer may damage the leading edge, and you want your slot gaskets left flat (in the normal closed position), so they do not take on a permanent bend. If the centerboard up control does not have a shock cord take up, You can put the line into a cleat, so the board is held all the way up, in the centerboard trunk. Remove the dagger board completely from its slot.
- Rudder care. Lay the rudder in the boat, or buy or make a rudder bag and put the rudder blade in the bag as one of the first steps in derigging the boat. Also check your rudder fittings. There should be no play in them. Replace them when they are worn.
- Rig. If leaving the boat with the mast rigged leave the boat with a little rig tension to support the mast, but not so much as to load up the boat.
- Cover. The boat should be covered with a good top cover that shields the boat from UV radiation. If the cover has holes in it, fix it or replace it. Figure out how to support the cover so that water does not collect in it.
- Salt. Rinse salt water off the boat, rinsing out blocks, lines and once in awhile, inside the tanks. If the tanks ever leak, you get salt in the tanks, and you will want to rinse that out from time to time.
- Turnbuckle grease. If you have adjustable angle spreaders, lubricate the adjusters. Use turnbuckle grease. If you don't lubricate these the stainless steel threaded part will permanently bond to the aluminum, and you will not be able to adjust them ever again.
- Inspections. From time to time complete a visual inspection of your boat. There are lots of highly loaded areas on a small sailboat. The chainplates are among them. Check where your shrouds and forestay or jib halyard attach to the hull. Watch for cracks that could let water into wooden reinforcements. Heavily loaded fasteners should be epoxied into the boat. From time to time take your centerboard out of the boat and check both centerboard and rudder for dings, cracks etc. Pay particular attention to the centerboard bolt hole. If the bolt hole has been damaged such that water can get in, wooden cored boards will soak up water, start to rot and will be weakened. Seal all bare wood with epoxy. Anytime you run aground you should check the centerboard. Inspect all lines from time to time, replace worn lines.

Note: This requirement should be done under the supervision of an adult, with a rescue boat, to give assistance if needed.
If you see a person fall off a sailing boat, you should immediately take the following steps.
- Shout 'Man Overboard' to alert the captain and anyone else on board.
- Throw a life preserver or personal flotation device near the person in the water.
- (Not directly at him, nearby, but somewhat windward (upwind) of him is best)
- Assign a person (if available) to keep constant visual contact with the man over board (MOB). This person should try their best to keep their eyes on the MOB and know where he is in the water. This person should talk to the MOB constantly during a recovery keeping communications between the boat and the MOB. If sailing with only two people and one should fall over, the remaining person must act as both captain and contact person.
There are two ways generally understood to bring the boat back to pick up the MOB.
- Either tack or jibe the boat around as quickly as possible and approach the MOB on a close reach to his leeward (downwind) side. Approaching from the leeward side avoids the danger of having the wind push the boat into or over the MOB.
Jibing the boat around can be quicker than tacking, but should only be done when wind conditions make jibing quickly a safe maneuver.
- The second method is also known as a "quick stop". Tack immediately after the person has fallen overboard, and keep your jib cleated in place. The jib will turn the boat, and the captain luffs the main to allow the boat to drift toward the MOB. This method keeps the boat close to the MOB, which keeps the boat in contact with the MOB. This should not be attempted in high winds where keeping the jib cleated could cause a capsize.
In all three cases, if the MOB can't reach the boat as you approach, hold out a paddle for the person to grab.
It is a good idea to practice Man Overboard maneuvers. Dropping a filled 5 gallon bucket into the water and using it as a dummy makes a pretty realistic simulation. Lifting the bucket full of water over the transom gives you an idea of how it might feel to help a waterlogged sailer back on board.

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 too 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
Fall down into the area between the hull and boom and swim out the back QUICKLY, ensuring you are not caught on any ropes. If the boat is very nearly turned upside down on top of you, however, then feel free to go out the side. 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 it is 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.
