Long and short are not synonyms, rather they are antonyms. Words that have the same meaning (such as big and large) are synonyms. Words that have opposite meanings (such as big and small) are antonyms.
Yes, the word 'bread' does have the short e sound. But not all words that have the e and a together make the same short e sound. An example of a word where the e and a make the long e sound is bead. But you also have words that are spelled exactly the same but sound different and mean different things, such as lead (with a long E meaning show someone the way) and lead (with the short e meaning a heavy metal). Or tear (with short e means to rip) and tear (with long e means the drops that fall when someone cries).
Short
is cancel short or long vowel
short e, as bed,
On seagoing vessels in restricted visibility a prolonged blast on the ships whistle means the vessel is making way through the water.
A. Three long blast of the ships whistle or general alarm at an interval of three, means a man overboard. This is dismissed by three short whistle blast. B. Three Short blast can also be Rule 34 (Inland and International) "Maneuvering and Warning Signals." Three short blast means "I am operating astern propulsion."
it means to blow a horn ok bye thanks for reading
This one long blast serves as a warning to other craft that there is an unseen vessel in the area. Be on alert!
There are particular sound signals that are to be used when you first get underway. One prolonged blast signifies that you are about to get underway. If you are going to make way in reverse, you need to signal an additional 3 short blasts.
You need to transmit the Morse letter D (-..) with either a fog horn or hitting a bell every 2 minutes. Long blasts need to be 3 times as long as short blasts. The space between blasts is as long as the duration of a short blast. So the sequence goes like this: Blow the horn or hit the bell for 6 seconds, wait for 2, hit it for 2 seconds, wait for 2 seconds, and hit it again for 2 seconds.
The sound signal short-long-short is an optional, additional signal made by a vessel at anchor in restricted visibility. The signal may be made by such a vessel in addition to her required sound signal to give warning of her position and of the possibility of collision to an approaching vessel.Collision Regulations 35(g)
it means you want to ask to go through the lock
Be careful, know where you are going, warn other ships of your presence (one long blast of a horn or similar)
It is called a short salute and is how ships greet each other.
One long blast can mean one of many things: 1) I am turning to starboard 2) In a situation of restricted view (ie turning a blind corner on a river) it's a warning signal to warn other vessels of your presence 3) In fog it is a general fog signal for vessels over usually over 12meters underway (this is repeated every 2 minutes)
One short blast of a boats horn can mean a couple of things.Horns are used to communicate with other boats to avoid collisions.If you are overtaking a boat from the rear, one short blast will let the other boat know that you are going to pass them on the starboard side, two blasts indicate passing on the port side. The other boat should return your one blast, or two blasts, to let you know that they are aware of you and acknowledge your intentions.If you are heading straight towards another vessel, one blast will indicate you intentions of passing port to port. If you pass starboard to starboard then two blasts are required. The last situation is if you are going to be crossing in front of another boat. Remember, the boat coming from the right has the right of way. Giving one blast lets the boat to your right know that you see them and are going to give way to them, again all these signals should be acknowledged by the other vessel. If you do not receive a return signal, assume they are either drunk or do not see you. These rules are for inland waters, such as lakes rivers, bays, harbors and the like. Different rules may apply when you are on the high seas.One short blast of a boat horn means that the boat is altering course in a starboard direction. One long blast means that the boat is nearing a bend and cannot see oncoming boats.
