Freeboard (nautical) A graphical representation of the dimensions used to describe a ship. f is the freeboard. In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. [1] In commercial vessels, the latter criterion ...
Bow (watercraft) The bow ( / baʊ /) is the forward part of the hull of a ship or boat, [1] the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. [2] Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline.
The low freeboard meant that these ships were unsuitable for ocean-going duties and were always at risk of swamping, flooding and possible loss. However, it greatly reduced the cost and weight of the armour required for protection, and in heavy weather the sea could wash over the deck rather than heeling the ship over.
They were low-freeboard, steam-powered ironclad vessels, with one or two rotating armored turrets, rather than the traditional broadside of guns. The low freeboard meant that these ships were unsuitable for ocean-going duties and were always at risk of swamping and possible loss, but it reduced the amount of armor required for protection.
As is typical for a late-19th-century vessel, several deckhouses may be seen. A deck is a permanent covering over a compartment or a hull [1] of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface.
The height and the weight of superstructure on board a ship or a boat also affects the amount of freeboard that such a vessel requires along its sides, down to her waterline. In broad terms, the more and heavier superstructure that a ship possesses (as a fraction of her length), the less the freeboard that is needed. Bridges
Cellular vessel. A cellular vessel is a container ship specially designed for the efficient storage of freight containers one on top of other with vertical bracings at the four corners. The majority of vessels operated by maritime carriers are fully cellular ships. [1]
Colourised engraving of a French galley (27 pairs of oars) built according to the design that was standard in the Mediterranean from the early 17th century; Henri Sbonski de Passebon, 1690. A galley was a type of ship which relied mostly on oars for propulsion that was used for warfare, trade, and piracy mostly in the seas surrounding Europe.
The Oliver Hazard Perry -class frigates were designed primarily as anti-aircraft and anti-submarine warfare guided-missile warships intended to provide open-ocean escort of amphibious warfare ships and merchant ship convoys in moderate threat environments in a potential war with the Soviet Union and the Warsaw Pact countries.
