对一条船而言,重要的定义是Freeboard deck, Poop deck or Raised quater deck 以及 Forecastle deck, Bridge deck等。 这些是load line等公约里面一些要求的核定基准!
而 tank top, 2nd deck, main deck/1st deck 以及01 acc. deck/A deck, 02 acc. deck/B deck, wheelhouse deck, compass deck等是实际应用的称呼!

如果有注意规范和Load line, Solas等公约,就会发现很多要求,比如通风口、透气口等的高度及关闭装置等,都是基于Freeboard deck而言的,也就是常说的干舷甲板。而main deck/主甲板,就是我们通常说的最底一层的连续的露天甲板! 根据不同的船型及干舷的计算,大部分情况下可以简单的认为主甲板即是干舷甲板。例外的情况需注意干舷计算!!

freeboard deck的定义是normally the uppermost complete deck exposed to weather and sea, which has permanent means of closing all exposed openings.

main deck的定义是The highest deck of the hull (also called the upper deck, see below), usually but not always the weather deck. Anything above the main deck is superstructure.

一般船的freeboard deck就是main deck,但特殊船型有不同,比如PCTC,他的main deck是最上面一层,而freeboard deck确是第5层甲板。

说到deck有好多说法,

Helo deck: Usually located near the stern and always kept clear of obstacles hazardous to a helicopter landing.

Hurricane deck: (River Steamers, etc.), the upper deck, usually a light deck, erected above the frame of the hull (deriving its name from the wind that always seemed to blow on the deck).[2]

Main deck: The highest deck of the hull (also called the upper deck, see below), usually but not always the weather deck. Anything above the main deck is superstructure.

Middle or Waist deck The upper deck amidships, the working area of the deck.

Orlop deck: The deck or part of a deck where the cables are stowed, usually below the water line. It is the lowest deck in a ship.

下面的简图是LOAD LINE里面的一些定义。 每个规范,公约里面在开始都有关于船舶参数、尺度的一些定义,之后的要求都是基于这些定义而言的!
