of 8' is pretty deep for many cruising destinations, marinas
, and small-boat anchorages
Notwithstanding, the So-Pac is notorious for deep anchorages
, where 8'-3" draft
shouldn't present too many problems.
Net Tonnage is a measure of volume of a ship, more precisely the volume of a ship that's useful for carrying cargo and passengers. So, essentially you take the internal volume of the ship, and remove the volume of the fuel
spaces, crew quarters and so on. 100 cubic feet is the volume used for calculating net and gross registered (GRT) tonnage of a ship.
Dead weight tonnage is the actual weight of what a ship can carry. To get this, you take the displacement
of a fully loaded ship and then subtract from that the displacement
of it when totally empty. And since displacement is actually the amount of water
displaced by a vessel, it corresponds to the actual weight of the ship.
See the USCG “TONNAGE GUIDE FOR SIMPLIFIED MEASUREMENT”
For purposes of Regulatory Measurement (GRT / NRT):
means the vertical distance taken at or near amidships from a line drawn horizontally through the uppermost edges of the skin (outside planking or plating) at the side of the hull
(excluding the cap rail, trunks, cabins and deckhouses, and deck
caps) to the outboard
face of the bottom skin of the hull
, excluding the keel
. For a vessel that is designed for sailing where the interface between the “keel” and the “bottom skin of the hull” is not clearly defined (as is the case with an “integral” or “faired” keel), the keel
is included in the “overall depth”.
