Speaking of a fully submerged hydrofoil craft, all the hydrofoils attached to the foilstruts of the craft body are fully submerged in the water, so that the disturbing wave forces acting on the hydrofoils are very small in their foilborne cruising compared with the forces on the surface piercing hydrofoils. Therefore, the fully submerged hydrofoil craft gives us a very comfortable riding. On th...

One of the most efficient methods of reducing drag on planing craft is the use of transverse step on the bottom of a hull. Applying steps on the hull reduces the contact area with water and as a result, it reduces drag of the craft. Planing craft are able to have one or two transverse steps. In this paper, numerical hydrodynamic performance of the stepped planing craft and its step height effec...

Self propelled models under radio control have been used for many years to assess the manoeuvring and handling of ships, and occasionally small craft. The limitations for testing small, fast craft have been linked to the low model weight required and the ability to install enough power, as well as the cost of modelling. Recent advances in motor and battery technology, the availability of model ...

A comprehensive and critical review of literature pertaining to the study of planing craft is given within this work. This study includes monohull design, analysis and performance prediction for flat water; many features of the planing characteristics, including dynamic stability, the use of stepped hullforms, re-entrant transoms and flow characteristics are detailed. Work on the rough water se...

Logistic constraints and difficulties, as well as risks and economical impact of the bathymetric measurement activity, especially in shallow water, are known matters. This activity, in fact, normally implies the presence of human conductors and operators aboard motorized craft that often have to be transported in difficult to reach places or, even worse, have to operate in sites which are dange...

In this Paper, an algorithm which improves CRAFT algorithm’s efficacy is developed. CRAFT is an algorithm widely used to solve facility layout problems. Our proposed method, named Plasma, can be used to improve CRAFT results. In this note, Plasma algorithm is tested in several sample problems. The comparison between PALSMA and classic CRAFT and also Micro-CRAFT indicates that Plasma is successf...
