What Are Cardinal Marks?
Cardinal Marks are a crucial system of markings similar to safe watermarks but are essentially direction-based. Their name is derived from the mathematical concept of cardinality, or in simple words, grouping.Â
Subhodeep is pursuing Naval Architecture and Ocean Engineering. Interested about the intricacies of marine structures and goal-based design aspects, he is dedicated towards sharing and propagation of common technical knowledge within this sector which, at this very moment, requires a turnabout to flourish back to its old glory.

Foul anchors are those where the chain (or the rope for ancient ships) becomes entangled about the entire structure, or the anchor gets enmeshed by some obstruction underneath the sea level.
The weight of a vessel is a very interesting aspect in the first place. Unlike all other physical objects, when we talk about the weight or mass of a vessel or any floating object in general, we usually allude to displacement.
There are mainly three modes of transportation: airways, waterways and land routes. Now, regarding water transport, there can be various classifications other than the types of vessels or watercraft. Let us look at a few.
Deck plating thickness can vary widely depending on a host of factors ranging from ship type to the region of disposition of the plate. Learn more about deck plating inside the article.
Multi-hull vessels are vessels that are characterised by the construction of multiple hulls, either two or three, known as catamarans and trimarans, respectively.
Freeing ports were introduced as per Load Line 1966 regulations to mitigate this problem. These are well-defined openings on the bulwark plate itself in certain numbers and intervals.
For a vessel, the turning circle measures its turning ability as the extent of the smallest circle made by applying a constant turning moment. In simpler words, it determines the ease or rapidness with which a floating vessel can swerve or veer past any obstacle.
A freeboard is a minimum distance between the exposed deck edge and the waterline for a floating vessel. In other words, it is the difference between depth and draft.
