Waterplane coefficient (C w) is the waterplane area divided by L WL x B WL. The waterplane coefficient expresses the fullness of the waterplane, or the ratio of the waterplane area to a rectangle of the same length and width. A low C w figure indicates fine ends and a high C w figure indicates fuller ends.
A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, minimizes a vessel's response to sea state, even in high seas and at high speeds. The bulk of the ...
In fluid dynamics, the wetted area is the surface area that interacts with the working fluid or gas. In maritime use, the wetted area is the area of the watercraft's hull which is immersed in water. This has a direct relationship on the overall hydrodynamic drag of the ship or submarine.
For instance, in the latter, Simpson's 3rd rule is used to find the volume between two co-ordinates. To calculate the entire area / volume, Simpson's first rule is used. [7] Simpson's rules are used by a ship's officers to check that the area under the ship's GZ curve complies with IMO stability criteria.
Semaglutide — the type 2 diabetes and weight loss medication sold under the brand names Ozempic and Wegovy — can expire. If you’ve ever given old milk a sniff, you know for yourself that ...
Beam – A measure of the width of the ship. There are two types: Beam, Overall (BOA), commonly referred to simply as Beam – The overall width of the ship measured at the widest point of the nominal waterline.

The Boston metro area and other parts of Massachusetts may also see squalls, winds and other dangerous conditions. Snow here, snow there, snow everywhere: US gets snow in all 50 states.
