How fast in knots did a caravel ship go?
Remember that the speed varies according to the wind.
Which is the proper route to take when overtaking another craft?
The boat coming from behind has no rights. It must overtake the slower boat safely whichever side it chooses.
A powered vessel:
Rule 35 - Sound Signals in Restricted Visibility
In or near an area of restricted visibility, whether by day or night the signals prescribed in this Rule shall be used as follows:
(a) A power-driven vessel making way through the water shall sound at intervals of not more than 2 minutes one prolonged blast.
(b) A power-driven vessel underway but stopped and making no way through the water shall sound at intervals of no more than 2 minutes two prolonged blasts in succession with an interval of about 2 seconds between them.
(c) A vessel not under command, a vessel restricted in her ability to maneuver whether underway or at anchor, a vessel constrained by her draft, a sailing vessel, a vessel engaged in fishing whether underway or at anchor and a vessel engaged in towing or pushing another vessel shall, instead of the signals prescribed in paragraph (a) or (b) of this Rule, sound at intervals of not more than 2 minutes three blasts in succession, namely one prolonged followed by two short blasts.
(d) A vessel engaged in fishing, when at anchor, and a vessel restricted in her ability to maneuver when carrying out her work at anchor, shall instead of the signals prescribed in paragraph (g) of this Rule sound the signal prescribed in paragraph (c) of this Rule.
(e | d) A vessel towed or if more than one vessel is towed the last vessel of the tow, if manned, shall at intervals of not more than 2 minutes sound four blasts in succession, namely one prolonged followed by three short blasts. When practicable, this signal shall be made immediately after the signal made by the towing vessel.
(f | e) When a pushing vessel and a vessel being pushed ahead are rigidly connected in a composite unit they shall be regarded as a power-driven vessel and shall give the signals prescribed in paragraphs (a) or (b) of this Rule.
(g | f) A vessel at anchor shall at intervals of not more than 1 minute ring the bell rapidly for about 5 seconds. In a vessel 100 meters or more in length the bell shall be sounded in the forepart of the vessel and immediately after the ringing of the bell the gong shall be sounded rapidly for about 5 seconds in the after part of the vessel. A vessel at anchor may in addition sound three blasts in succession, namely one short, one long and one short blast, to give warning of her position and of the possibility of collision to an approaching vessel.
(h | g) A vessel aground shall give the bell signal and if required the gong signal prescribed in paragraph [(g) | (f)] of this Rule and shall, in addition, give three separate and distinct strokes on the bell immediately before and after the rapid ringing of the bell. A vessel aground may in addition sound an appropriate whistle signal.
(i | h) A vessel of less than 12 meters in length shall not be obliged to give the above mentioned signals but, if she does not, shall make some other efficient sound signal at intervals of not more than 2 minutes.
(i) A vessel of 12 meters or more but less than 20 meters in length shall not be obliged to give the bell signals prescribed in paragraphs (g) and (h) of this Rule. However, if she does not, she shall make some other efficient sound signal at intervals of not more than 2 minutes.
(j | h) A vessel of less than 12 meters in length shall not be obliged to give the above mentioned signals but, if she does not, shall make some other efficient sound signal at intervals of not more than 2 minutes.
(k | i) A pilotage vessel when engaged on pilotage duty may in addition to the signals prescribed in paragraph (a), (b) or [(g) | (f)] of this Rule sound an identity signal consisting of four short blasts.
(k) The following vessels shall not be required to sound signals as prescribed in paragraph (f) of this Rule when anchored in a special anchorage area designated by the Secretary:
(i) a vessel of less than 20 meters in length; and
(ii) a barge canal boat, scow, or other nondescript craft.
Fender strips are available at marine supply shops.
What should a motorboat do when it is approaching a sail boat?
sail boat has the right of way and same applies to all other boats larger than yours
Are Sailboats required to have a white mast light?
Checking with the authorities in charge of the waters in which you will operate your vessel is ALWAYS advisable.
How are pulleys used in a boat mast?
#1: There's a pulley at the top of the mast for raising/lowering sail,
#2: Thers's a system of pulleys below the boom to prevent the aft end of the boom from rising, this is called the "boom vang",
#3: There's a pulley at the aft end of the boom to facilitate lateral adjustment of the aft end of the boom for the purpose of adjusting the angle of the mains'l to the wind.
All these pulleys affect the mast:
The boom vang prevents undue pressure on the mainstay, minimizing pressure on the base of the mast, minimizing the danger of dismasting.
The pulley at the aft end of the boom optimizes the lift caused by the foiling of the wind about the sail.
The pullley at the top of the mast facilitates rapid raising/lowering of sail.
The Triangular sail set furthest foreward on a vessel with two or more such sails?
it is called a flying jib
What must you do in a No Discharge Zone if your boat has a y valve?
Be certain thet the Y valve is secuered in the closed position
What equipment is a boat traveling further than 1 mile offshore required to have?
Hawaii requires all recreational vessels going more than one mile off-shore to be equipped with a USCG approved Emergency Position Indicating Radio Beacon (406 MHz) or a VHF radio.
What is A ship with square and triangular sails?
"Square-riggers" have primarily square sails, but the jib sails are triangular.
What is the name of the boat that Jim Hawkins sails aboard?
The Hispaniola is the name of the fictional vessel featured in Robert Louis Stevenson's classic adventure novel, Treasure Island, which Jim Hawkins sails aboard.
Who sailed in the boat Tom Thumb?
Tom Thumb was a small boat sailed by the famous American author and adventurer, John M. McGowan, in the 19th century. It gained notoriety for its role in a series of voyages, including a notable trip across the Atlantic Ocean in 1850. The vessel's name is often associated with the larger-than-life tales of adventure and exploration during that era.
What does a green can shaped buoy mean?
In Region B a "green can shaped buoy" stands for the edge of a channel on a boaters left side when entering from open sea or heading upstream, the opposite applies in Region A.
The power vehicle is on the right, therefore it is looking at the other vehicle's green light, making the vehicle on the right the stand on vehicle (meaning it maintains present course and speed).
When a sailboat is approaching a power-driven vessel which one is the give-way vessel?
the power driven vessel needs to give-way for sailing ships.
How does a sailor measure boat speed?
Boat speed is traditionally defined as how fast your boat is moving with respect to the water. This is an important definition as I've seen boats running at top speed but unfortunately for them they were caught in a strong current so the boat was not moving at all, or moving backward, with respect to the ground. (That is called Speed Over Ground.)
Speed with respect to the water is measured by dipping something in the water, like a log or a paddle-wheel, and measuring how fast the water is moving by. For example if you have a boat that is 10 long (feet, meters, I don't care), and you throw something in the water at the front of the boat and notice it takes 1 second to get to the back of the boat, then your speed is 10/second. A paddle wheel you would see how fast it turns and compare it to other known speeds. The advantage of this technique is it gives you continuous readings. Boat speed instruments are based on this technique and involve a miniature paddle installed on the outside of the hull.
Or you can use devices that track location, like a sextant or GPS, and see how far you have traveled over the last hour and that is your speed per hour.
How many boats are sailing the ocean at one time?
There are too many variables associated with answering this question.
The first person to sail around the earth?
Ferdinand Magellan is often credited with the achievement, however, he died in the Philippines after crossing the Pacific Ocean. 18 members of his crew, out of an original 234, survived the entire trip to return to Spain.
There are sail planes, sail boats, sail cars, and with a spaceship you could sail to the stars.
