What is a plum bow?

A vertical, or unraked bow having a straight edge is known as a plumb bow. These bows have maximum waterline besides an X-Bow or an Inverted Bow. This length of the waterline allows for a greater hull speed.

What is the ship's bow called?

Prow. The "prow" (French : proue) is the forward-most part of a ship's bow above the waterline. The terms prow and "bow" are often used interchangeably to describe the most forward part of a ship and its surrounding parts.

What is an Atlantic bow on a ship?

Atlantic bow

These vessels were built with a relatively low fore end which proved very wet except in a calm seaway. The answer was to adopt a raised bow with noticeable shear and flare that kept the foc'sle much drier than before and made weaponry nearby easier to operate.

How much fuel could be saved by building a bulb bow?

1 INTRODUCTION. Bulbous bow can help to reduce a ship's resistance and thus to save the fuel consumption up to 15%, however, it is also regarded as a threat to a struck ship in collision accidents because it may generally penetrate the side shell of the vessel, which may cause the leakage of hazardous goods.

What does red on deck mean on a boat?
