How do you measure the overall length of a boat?

How do you measure the overall length of a boat?

Length overall is measured from the tip of the bow in a straight line to the stern of the vessel. Bowsprits; rudders; outboard motors and motor brackets; handles; and other fittings, attachments, and extensions are not included in the measurement.

How do you measure the height of a boat?

How to Measure Your Boat for Transport

1. Overall Length is measured from the tip of the bow to the center of the stern.
2. Overall Height is measured from the bottom of the keel to the highest non-removable part of the boat.
3. Beam is measured from the widest point of the boat, including the rub-rail.

How do you measure the depth of a boat?

The depth is measured at the middle of the length, from the top of the keel to the top of the deck beam at the side of the uppermost continuous deck.

What is the depth of a boat called?

Draft:The distance between the waterline and the keel of a boat; the minimum depth of water in which a boat will float.

What do you call the height of a boat?

Freeboard is all about flooding the ship. It’s how high water can come up without water coming onto the deck and entering the ship, so freeboard is defined by the lowest point of entry of water. But that’s not what you’re asking. Air draft of course is the ship’s height above water, or how low a bridge it can go under.

How do I remember my starboard port?

It’s easy to remember using this commonly used mnemonic: “There is no RED PORT wine LEFT in the bottle.” See what we did there? That one little phrase lets you remember that the port side is on the left, and it will be using a red navigation light.

What are the holes in the back of my boat for?

There are two holes in the back of the transom (one has a plug in it), both below the water line, per the attached picture. The one on the right is for draining the water out of your boat (bilge drain), the other one will be for a bait tank or raw water wash down (hope its capped of well).

What side do you pass on in a boat?

You must take early and substantial action to keep well clear of the other boat by altering your speed and course. You should pass at a safe distance to the port (left) or starboard (right) side of the other boat. If a safe route exists, you should always attempt to pass the boat on the starboard side.

What is the standard size boat plug?

1-inch

What is the plug on a boat?

: a wood or metal plug stopping up the drainage hole near the keel of a boat and removable when the boat is dry-docked to drain out bilge water.

Are boat drain plugs standard size?

1/2″ is the standard drain plug size.

What is a bilge plug?

: boat plug If your boat has a bilge plug, remove the plug when the boat is out of the water so that any water that has accumulated in the bilge can drain free.— Twain Braden, The Handbook of Sailing Techniques, 2003.

Why is there always water in the bilge?

Water can enter a boat through various sources. This water may include substances such as debris, detergents, seawater from leaks or rough seas, rainwater, and so forth. Since the bilge is the lowest part of a boat, all unwanted water is collected when the boat is resting or in still waters.

Why does the bilge fill with water?

Bilge water Water that does not drain off the side of the deck or through a through hull, typically via a scupper, drains down into the ship into the bilge. This water may be from rough seas, rain, leaks in the hull or stuffing box, or other interior spillage.

What is the purpose of a bilge?

The bilge is the lowest inner part, or bottom point, on a boat, and is designed to collect excess water. On vessels of virtually any size, a pump inside the bilge performs a very important function: to remove accumulated water by creating pressure or suction so that the water can be removed.

How does the bilge system work?

A piping system intended for disposing of water that may accumulate in spaces within the vessel (holds, machinery spaces, cofferdams) due to condensation, leakage, washing, fire fighting, etc. It is to be capable of controlling flooding in the Engine Room as a result of limited damage to piping systems.

Is a bilge pump necessary?

Bilge pumps are that last line of defense against your boat sinking. Unfortunately, most boaters believe that one pump is sufficient. That is actually the bare minimum required, and three or four pumps per craft is recommended.

How bilge suction should be checked for efficient working?

To check that the bilge suction and bilge suction line are clear and working correctly, a nominal amount of clean water should be poured into the bilge well and pumped out. If cargo debris is trapped in any of the non return valves it will reduce the pumping efficiency of all the other hold bilges.

What is the purpose of emergency bilge suction?

The emergency bilge suction or bilge injection valve is used to prevent flooding of the ship. It is a direct suction from the machinery space bilge which is connected to the largest capacity pump or pumps. An emergency bilge pump is required for passenger ships but may also be fitted as an extra on cargo ships.

When should I pump my bilge?

Bilge Water on board ships The collected water may contain various contaminants including oil and lubricants and must be pumped out periodically when the bilge holding tank gets filled.

What should you look when inspecting a cargo space?

Items to be inspected

• Check that the designated compartments are clean and ready to receive cargo.
• Check that the drainage and bilge suctions are working effectively and that bilge wells are dry.
• No leakage from ballast tanks present.
• Sounding pipes and air pipes passing from holds are clean and rust free.

What are most basic and common visual inspection method?

“Eyeballing” is the most common and readily available method of initial data assessment. Experts in pattern recognition maintain that the “eyeball” technique is still the most effective procedure for searching arbitrary, possibly unknown structures in data.

How much grain can a cargo ship hold?

While buying in bulk can sometimes be economical, it also can put pressure on an importer’s working capital. A standard 20-foot shipping container holds only around 20 tonnes of grain.

How is the procedure of cargo preparation prior to loading?

How to prepare cargo holds prior loading

1. The compartment should be swept clean, and all traces of the previous cargo removed.
2. Bilge areas should be cleaned and all ‘bilge suctions’ seen to be working satisfactorily.
3. The fire/smoke detection system should be tested and seen to function correctly.

What is the reasons why using dunnage for cargo loading?

In general, dunnage also protects goods and packaging from contamination and moisture. By protecting cargo from damage, dunnage helps improve customer relationships and allows for easier loading of fragile cargo.

What are the possible things to be done for Hold preparation?

Cleanliness/preparation – specific cargo may require additional measures

1. remove all previous cargo residues, loose rust and scale.
2. after salt water washing, final rinse should be with freshwater.
3. check for hairline cracks on internals and plating after the holds are washed and cleaned.

How do you clean holds after discharge of a general cargo?

3. Normal Clean

1. Cargo residues be removed.
2. Double sweep the holds clean.
3. Seawater wash down.
4. Fresh water rinse.
5. Allow the holds to thoroughly dry.
