1. From theoretical and experimental point of view, we show the possibility to trarmfono wave energy into shipthrust by using the bow fin2. In the sea condition such as calm nun very rough sea condition, it is better to stow the fins into tp hull. Effective sea condition of the fin system is determined by the proposal concept3. By controlling the bow fin, We can reduce the roll motions like antirolling fin which is usually equipped at the midship section. The system of anti rolling fin is well known and well established. As the result, that system can be equipped at the bow without the difficult problems.4. We propose the new fin :wing system at the bow part where the stowing space is very narrow than midship part. The proposal bow slowing systm is that one fin is put on the other fin5. By controlling the bow fins, we propose the new rushinglesscontainersystem6. We propose not ordy the bow fin system but other method. The another one is that we propose to build the moonpool at the bow part. At the moon pool the wells turbine is equipped to generate electric power by using up and down flow which is caused by ship modons

1.本文从理论和实验两方面论证了利用艏鳍将波浪能转化为船舶推力的可能性。在无风或大风浪等海况下，最好将鳍片装入船体内。鳍系统的有效海况由建议方案确定。通过控制艏鳍，我们可以减少横摇运动，如减摇鳍通常安装在中剖面。减摇鳍系统是众所周知的，并且是完善的。因此，该系统可以配备在船头没有困难的问题。4.本文提出了一种新的鳍-翼系统，该系统位于船艏部分，其装载空间比船中部分非常狭窄。建议的船首减速系统是一个鳍放在另一个鳍上。通过控制船首鳍，我们提出了新的无冲容器系统6。我们建议不采用弓鳍系统，而采用其他方法。另一个是我们建议在船头部分建造月池。在月池处，威尔斯涡轮机被装备成通过利用由船舶模块引起的向上和向下流动来发电
