    The WNA mark ( Winter North Atlantic mark) is required by the ships lesser than 100 mtrs in length trading in North Atlantic Ocean during the Winter Season. During the first conference on the Loadline convention it was generally agreed that the freeboard of small ships should be especially examined with a view to some increase being made ( in freeboard) . Statistics of ship losses had highlighted the safety problems associated with vessels under 300 ft long and some action was necessary. It was recognized that it was difficult for ships lesser than 100 mtrs ( 328 feet) to (more)

    Each position circle found using the Sextant Altitude is of immense radius. Therefore, any short length of the arc of some circle can be considered as an straight line . Comparing the observed distance to the celestial body the calculated distance using an estimated position provides the distance towards, or away from the body.. The observed distance is known as the True Zenith Distance (TZD.) The value based on the assumed position is the Calculated Zenith Distance (CZD.) The difference between the two is known as the Intercept. The closest point on this circle is known as the Intercept Terminal (more)

They have greater subdivision 3. The cargo of oil has generally more buoyancy than the bulk cargo or general cargo 4. They have more pumps to quickly control the water ones in case of an bilging or flooding incident 5.
