Cellulose, the main component in natural fibers will deteriorate with age, getting more brittle and turning yellow or brownish
During bending, line strength may decrease up to five times |
|
|
Term
|
Definition
When natural fiber line is under strain, the friction of the fibers, yarns and strands against each other, causes internal wear
Upon opening the lay of the line, any presence of a white powdery substance indicates small particles of line worn off by friction. |
|
|

Definition
Damage to internal natural fibers occurs when a line under a strain exceeds 75% of its breaking strength |
|
|
Term
Overloading or Shock-Loading |
|
Definition
Signs that a line was overloaded are elongation and hardness
If the circumference is reduced by five percent or more, the line should be replaced.
Another indication of synthetic line overloading is hardness to the touch. This can be noticed while gently squeezing the line. |
|
|

Term
|
Definition
The most common method of stowing the extra line on deck or on the dock after making fast to a cleat is to coil it. |
|
|
Term
|
Definition
Flemishing a line consists of coiling a line clockwise against the deck. It is used for appearance |
|
|
Term
|
Definition
A common seamanship practice says that the WLL of a line should be not more than one-fifth of its BS,This five-to one safety factor allows for sudden strains, shock-loading, and normal deterioration as the line ages

The estimated WLL of a shackle, in tons, is calculated by using the formula
WLL = 3 x D2. |

Flare is the outward turn of the hull as the sides of the hull come up from the waterline. |
|
|
Term
|
Definition
Tumble home is the reverse of flare and is the shape of the hull as it moves out going from the gunwale to the waterline. |
|
|
Term
|
Definition
A deck usually curves athwartships, making it higher at the centerline than at the gunwales so the water flows off the deck. This curvature is called camber |

The turn of the boat’s hull below the waterline is called the chine. It is “soft” if it is rounded, and “hard” if it is squared off. |

Deadweight is the difference between the light displacement and the maximum loaded displacement of a boat and is expressed in long tons or pounds |

The stem is an extension of the forward end of the keel. |
|
|
Term
|
Definition
The sternpost is a vertical extension of the aft end of the keel |
|
|
Term
|
Definition
The bar keel is popular because its stiffeners protect the boat’s hull plating if the boat grounds on a hard bottom. It also reduces rolling. A disadvantage of the bar keel is that, because it extends below the bottom of the boat, it increases the boat’s draft. |
|
|
Term
|
Definition
The flat plate keel has a plate that is perpendicular to the centerline of the hull.The vertical center keel is often provided with a flange top so that when combined with the flat plate keel the section resembles an “I” beam |
|
|
Term
Rounded Cruiser-Type Stern |
|
Definition
The rounded, cruiser-type stern presents less flat surface area for a following sea to push upon and tends to split the waves of a following sea, allowing it to pass forward along each side of the boat. Thus, the wave has minimum impact |
