When a ship is arriving at a port and makingthree blasts, it can also means he is slowing down. Thiscould be an announcement to tug boats that are standing byto assist they will soon be needed because the ship isdropping below maneuvering speed and will soon needassistance.
One short blast tells other boaters "I intend topass you on my port (left) side." Two short blasts tellother boaters "I intend to pass you on my starboard (right) side."Three short blasts tell other boaters, “I am operatingastern propulsion.” For some vessels, this tells otherboaters, “I am backing up.”
Generally the ships sound their horns tobe in compliance with navigation rules. While they occasionallysound there horns as a salute, generally they are signalingtheir intentions to help avoid collisions. As an example, theship will sound 3 short blasts to signal that theyare about to backup.
This horn signal indicates danger and can be usedto communicate potential collision with another vessel. It can alsobe used while approaching a vessel that is oncoming that youdo not understand their intentions or are otherwiseconfused by their actions.
When you are approaching a river lock, you areexpected to sound one prolonged blast and one shortone in order to signal to the lock attendant that you want topass through. You are to sound the blast when you are aboutone mile away from the river lock.
RULES OF THE ROAD
Unlike the roads in the UK, you drive on theright hand side of the River and pass oncoming boats port(left) side to port side. When overtaking other boatsyou do so on its port side towards the middle of theriver.Each boat alters course to starboard (right) andpasses port to port (left). Always assume this situation exists. Aboat approaching from your starboard (right) side hasright of way. If you are approaching another boat from itsstarboard side, you have right of way.
A foghorn or fog signal is a device that uses sound towarn vehicles of navigational hazards like rocky coastlines, orboats of the presence of other vessels, in foggy conditions. Theterm is most often used in relation to marinetransport.
Red triangular daymark is a type of lateralmarkers. These markers indicates the navigation and marks the safewater areas. Red triangular daymark marks the channel on theindividual starboard (right side) when an individual enters fromthe upstream. The numbers on the markers increses as one returnfrom the upstream.
If you hear the fog signal of a vesselyou cannot see, slow to a minimum speed until you aresure there is not a risk of collision. One prolonged blastat intervals of not more than two minutes is the signal usedby power-driven vessels when underway.
If you do not agree with or understand clearlywhat the other vessel's intentions are, you shouldsound the danger or doubt signal (5 short, rapidblasts). Each vessel should then slow or stop untilsignals for safe passing are sounded, understood and agreedto.
A boatswain's call, pipe or bosun's whistle is apipe or a non-diaphragm type whistle used on navalships by a boatswain. It is pronounced, and sometimesspelled, "bosun's call".
The required lights are: Red and green sidelightsvisible from a distance of at least two miles away—or if lessthan 39.4 feet (12 meters) long, at least one mile away—on adark, clear night. An all-round white light (if vessel isless than 39.4 feet long) or both a masthead light and asternlight.
Sidelights: These red and green lights are calledsidelights (or combination lights) because they are visibleto another vessel approaching from the side or head-on. The redlight indicates a vessel's port (left) side; the greenindicates a vessel's starboard (right) side.
It usually consists of a source which producescompressed air, which passes into a horn through a reed ordiaphragm. The stream of air causes the reed or diaphragm tovibrate, creating sound waves, then the horn amplifies thesound making it louder.
To determine a 'safe speed' for your boat, takeinto account the following factors: The visibilityconditions (fog, mist, rain, darkness) The wind, water conditionsand currents. Traffic density, type of vessels in the area andtheir proximity.
Let's look up anchor and masthead lightsin the Glossary: Anchor light. A white light thatshines so it is visible from all around the vessel required whenanchored or moored between sunset and sunrise. A whitelight shinning forward through an arcof 225° indicatinga vessel is under mechanical propulsion.
A distress signal is typically a call forhelp sent out by a person or ship. But since thetravel through waterways is one that has been around the longest,most frequent uses of emergency signals are made byships in danger. A distress signal is essentiallysomething that will attract attention to attain somehelp.
The general emergency signal is a signalused on board ships in times of emergency. The signalis composed of seven or more short blasts followed by one longblast on the ship's whistle and internal alarmsystem.
Red and Green buoys and lights indicate primarychannels. If the green horizontal band is on top, theprimary channel is the right (starboard). If the redband is on the top, the primary channel is to the left (port)side. This marker indicates the primary channel is on thestarboard.
In recent years, the most common causes ofboating accidents in Florida have included (in order offrequency): operator inexperience, lack of proper look-out,operator inattention, excessive speed, machinery failure,careless/reckless behavior and hull failure, followed by hazardouswaters, alcohol use, and a number of
Nun Buoys. These cone-shaped buoys arealways marked with red markings and even numbers. Theymark the edge of the channel on your starboard (right) sidewhen entering from the open sea or heading upstream.
Standing up in a boat is most likely to cause someoneto fall overboard especially if someone starts to rockthe boat or if a wave occurs and the person standing is notprepared of the said situations. You may also consider thecauses standing on a slippery surface and slip off aswell.
Sound signals when altering course toport. Applying the Rule(s) and comments: In accordance withRule 34 (a) (Manoeuvring and warning signals), a vesselaltering its course to port (vessel A) shall indicatethat manoeuvre by two short blasts on her whistle.
Ship's bells are also used for safety in foggyconditions, their most important modern use. When a sailorhas died he or she can be honoured with the sounding ofeight bells; meaning "end of the watch". The term "eightbells" can also be used in an obituary, as a nauticaleuphemism for finished.
One short blast tells other boaters "I intend topass you on my port (left) side." Two short blasts tellother boaters "I intend to pass you on my starboard (right) side."Three short blasts tell other boaters, “I am operatingastern propulsion.” For some vessels, this tells otherboaters, “I am backing up.”
In international maritime language the sound signal offive short blasts means “I am not sure of yourintentions and am concerned we are going to collide”. Vesselsuse the audible signal of five short blasts to communicatethis alarm, using a horn, a whistle, or whatever is tohand.
One prolonged blast at intervals of not more thantwo minutes is the signal used by power-driven vessels whenunderway. One prolonged blast plus two short blastsat intervals of not more than two minutes is the signal usedby sailing vessels.
A prolonged blast is also sounded when a vesselis approaching a bend in a river where vessels coming from anotherdirection cannot be seen. It is sometimes referred to as the“blind bend signal". Two Short Blasts - Thismeans "I intend to leave you on MY starboard side". FiveShort Blasts - This is the DANGER signal.
If the red buoys are on the right/starboard sideof the boat, then the green buoys should be on the left/portside of the boat when heading upstream. The opposite is true whentraveling downstream. Of course, this is fine if the boater cansee the buoy color.
(c) The term "prolonged blast" means ablast of from 4 to 6 seconds' duration. Whistles givecoded signals that are made up of one or more "blasts," eachof which will last either about one second (short blast) orfrom four to six seconds (prolonged blast). There are no"long" blasts in the navigation rules.
One prolonged blast is a warning signal (forexample, used when coming around a blind bend or leaving a dock).Five (or more) short, rapid blasts signal danger or signalthat you do not understand or that you disagree with theother boater's intentions.
