2. Freeboard (nautical) - Wikipedia

   en.wikipedia.org/wiki/Freeboard_(nautical)

   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 ...

3. Small-waterplane-area twin hull - Wikipedia

   en.wikipedia.org/wiki/Small-waterplane-area_twin...

   The twin hulls (blue) remain completely submerged. A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea, where wave energy is located, minimizes a vessel's response to sea state, even ...

4. Naval architecture - Wikipedia

   en.wikipedia.org/wiki/Naval_architecture

   Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation of marine vessels and structures. [1] [2] Naval architecture involves basic and applied ...

5. List of ship types - Wikipedia

   A two-masted, fore-and-aft rigged sailing boat with a mizzenmast stepped forward of the rudder and smaller than its foremast. Knarr A large type of Viking cargo ship, fit for Atlantic crossings Lorcha A sailing ship with mixed Chinese (rig) and western design (hull) that used since 16th century in far east. Landing Ship, Tank

6. Inverted bow - Wikipedia

   en.wikipedia.org/wiki/Inverted_bow

   In ship design, an inverted bow (occasionally also referred to as reverse bow) is a ship's or large boat's bow whose farthest forward point is not at the top. The result may somewhat resemble a submarine 's bow. Inverted bows maximize the length of waterline and hence the hull speed, and have often better hydrodynamic drag than ordinary bows.

7. Ship stability - Wikipedia

   en.wikipedia.org/wiki/Ship_stability

   Ship stability. Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on centers of gravity, centers of buoyancy, the metacenters of vessels, and on how these interact.

8. Carrack - Wikipedia

   en.wikipedia.org/wiki/Carrack

   c. 1558 painting of a large carrack attributed to Pieter Bruegel the Elder. A carrack ( Portuguese: nau; Spanish: nao; Catalan: carraca; Croatian: karaka) is a three- or four- masted ocean-going sailing ship that was developed in the 14th to 15th centuries in Europe, most notably in Portugal and Spain.

9. Pinnace (ship's boat) - Wikipedia

   en.wikipedia.org/wiki/Pinnace_(ship's_boat)

   As a ship's boat, the pinnace is a light boat, propelled by oars or sails, carried aboard merchant and war vessels in the Age of Sail to serve as a tender. The pinnace was usually rowed but could be rigged with a sail for use in favorable winds. A pinnace would ferry passengers and mail, communicate between vessels, scout to sound anchorages ...
