آنالیز رفتار دینامیکی لنج چوبی در امواج نامنظم

Dhow (LanJ) is a wooden vessel which is traditionally operating in Persian Gulf and Oman Sea. In contrast of its frequent lost, ordinary people believe that it has very good behavior at waves. In this study, by means of seakeeping computer software, authors have calculated its dynamic behavior in waves. Comparison between dhow performances in waves against seakeeping criteria has been made. Then, its operable sea waves is concluded. Then the reason behind people believe has been discussed, thoroughly. The end result is that the typical wooden dhow may withstand in waves of significant wave height of not more than 1 meter.
