Maritime transport is the main pillar of the global economy given that approximately 90% of all raw and processed products worldwide is made through it. The development of worldwide commerce led to the increase of maritime traffic with direct implications to the increasing risk of naval accidents with catastrophic consequences. The main cause of naval accidents remains the human factor, which is present in 80 - 90% of the cases. The key factor in obtaining performance is the human. Nowadays, a special role is given to counteracting the human errors in order to dimish the effects of naval accidents by introducing specialized software onboard vessels. Informatics has long passed the border concerning restricted categories of specialities. This has become a part of our daily life, an element that allows us to organize our activities better, thus increasing efficiency, productivity and providing fast solutions for routine activities. As a result, people have more spare time that can be devoted to other activities. The software ,,Officer of watch" (OOW), presented in this paper is addressed to the officers in charge of a navigational watch from the merchant vessels or navy ships and helps them in fulfilling the functional attributions on board. Also, this software can be used by military students from the specialization Navigation, Hydrography and Navigation Equipment and students from the specialization Navigation, Maritime and River Transport for solving various problems of navigation (dead reckoning and coastal, astronomical and great circle navigation). This software comes to replace a series of nautical documents and publications currently used by the deck officer of the watch in order to fulfill its functional attributions. The result can be seen as an immediate increase in labor efficiency by reducind the time needed to solve coastal, terestrial, astronomical and great circle navigation problems.
