I. T. to calculate, by thin ship theory, the effect of ship speed on the damping coefficients in pitch and heave for four diverse types of ship hulls--cargo ship, tanker, destroyer, and trawler. Results indicate that, for all four hull types, there is a marked increase in pitch ...
or ULDBs, and launched a whole movement of fast, fun speedsters based loosely out of Santa Cruz. A downwind flyer, some 160 boats were built in a 16-year production run that began in 1972. Moore 24s are still raced hard and often, even...

RIBs, or Rigid Inflatable Boats, are a type of boat that have rigid hulls and sides made of flexible tubes containing pressurized gas. The concept combines the buoyancy and stability of an inflatable boat with the performance and strength of a traditional hard-hulled boat. ...
Note that such cargoes require specialized vessels with hulls capable of withstanding large pressures. This is because of the peculiarity in the transportation conditions of such goods. For instance, LNG and CNG can cover large volumes in the gaseous form. Because of this, they cannot be stored ...
Another reason was also that the increase in international trade demanded a high quantity of the single commodity to be transported from one place to another. This was the primary reason for the introduction of different ship types. Primarily the transportation of bulk liquids began in the ...
