20,000 leagues is about 72,000 nautical miles. The title 20,000 Leagues Under the Sea is not actually referring to a journey to a depth of 20,000 leagues. Instead it is actually referring to a journey spanning a horizontal distance traveled ‘under the sea’.

6 feet

A fathom is a unit of length equal to 6 feet….Convert 10 Fathoms to Feet.

The fathom is not an International Standard (SI) unit, nor is it accepted internationally as a non-SI unit. However it is historically the most frequently employed maritime measure of depth in the English speaking world.

six feet

The name furlong derives from the Old English words furh (furrow) and lang (long). Dating back at least to early Anglo-Saxon times, it originally referred to the length of the furrow in one acre of a ploughed open field (a medieval communal field which was divided into strips).

A nautical unit used for measuring the lengths of the cables and chains (especially anchor chains), equal to 15 fathoms, 90 feet or 27.432 meters.

Brought up to three in water / four on deck: When the anchor is dropped and third joining shackle is in water and fourth joining shackle is on windlass (deck). Clear hawse: This term means that the cables are clear of one another when a ship is riding to two anchors.

Shackles – Quenched & Tempered

– The size of the 27.5 meters results from the conversion into meters of the length of 15 fathoms, which the British Admiralty used and is now universally established.

To protect against abrasion, a short length of chain can be shackled to an otherwise all-rope rode. The chain portion of these rodes is typically six to 30 feet long. For boats up to about 30 feet, a general rule of thumb is a boat length of chain.

One shackle is 15 fathoms, aka 90 feet. Universally used throughout the world. And for all practical purposes a cable, i.e. one tenth of a sea mile, is 200 fathoms, and guess how long a standard coil of rope is!

The shackle, also known as the bail, is a metal loop attached to one of the end rivets of a Swiss Army Knife. It can be used to attach the knife to a lanyard or chain, for instance on a belt.

The Strength Theory A soft shackle shares the load over four strands of the line. Theoritically, it would be 400% of the strength of the line it is made from. But the knot is generally the weak point. A diamond knot strength is somewhere between 25% and 40% the strength of the line it is made from.

A cervical collar, also known as a neck brace, is a medical device used to support a person’s neck.

Here are a few tips for sleeping with a cervical collar: Make sure your mattress offers good support. A mattress that’s too soft may not give your neck the support you need. Try to keep your neck in a neutral position, not bent forward, backward, or to the side.

A shackle is a u-shaped, load-bearing connecting device designed to be used with a removable pin. Shackles can be used in a number of different rigging and load securement applications to connect different types of lifting slings, chain, or rope to an object or to each other.

Lifting shackles of all body types are available in three basic pin designs:

• Screw Pin Shackles.
• Bolt Type Shackles.
• Round Pin Shackles.

Overloading The Hoist: Not surprisingly, the single most common way to potentially damage or misuse a chainfall is to overload the hoist. Putting too much force on the hook or exceeding the working load limit of the hoist leads to stretched hooks, damaged equipment, damaged loads, and employee downtime.

There are three main types of lifting slings that you can choose: chain slings, wire rope slings, and polyester slings.
