... This paper presents a comprehensive approach to optimizing the performance of wind-assisted ships. The proposed optimization framework simultaneously addresses ship routing and design, considering the complex interactions between design parameters and route optimization across multiple weather...

... The effects of multiple wings interacting and the change in efficiency due to those effects as well as optimal sheeting angles are becoming an important area of study with the advent of wind-propelled ships for goods transport. This research presents a first analysis of wind tunnel tests carried...

... relevant for commercial studies are presented. Sailing yacht studies have repeatedly shown how important it is to design and optimize the aero and the hydro aspects of the vessel in synchrony. This is equally or even more important for commercial ships, where part of the thrust might still come from...

... forces is proposed. The experimental measurements indicate that the ship is almost never in static equilibrium, which raises questions about the validity of models based on equilibrium principles. These questions have not yet been answered and are the topic of ongoing future research. maximum drive...

... is approximately 80° from the bow, and that with a typical heavy weather sail configuration Niagara would be at risk of capsize in about 40 knots of wind. These results are useful for learning about square rig sailing as well as providing guidance to the Niagara’s officers regarding survivability of the ship...

... Numerical simulation of maneuvering of “Naniwa-maru" was performed to clarify the maneuver characteristics in particular with wearing operation. "Naniwa-maru" belongs to a type called Higaki-kaisen, and the Higaki-kaisen is a type of the more generic class of vessels named "Bezai-ship". Bezai...

Our building blocks for such an integration are: a thousand-fold increase in PPP speed 3 , new editing tools which maintain Boatness 4 , and an accessible modularization of the engineering physics of the PPP within a new programming...

... Waves cause undesireable forces and motions in yachts which vary in severity from mildly uncomfortable to catastrophic. The problems created by waves are receiving serious and increasingly analytical attention from the naval architects who design oceangoing ships. Many of the physical phenomena...
