This article discusses maritime and other navigation-related terms proposed by V. Pakalniškis in his book The Explanation of Navigation Terms (2005). Terms proposed as substitutes to the words of foreign origin but not mentioned in other publications of this field have been researched. The composition and correct usage of these substitutes are analyzed, their use in other highly popular sources have been researched, and in cases of their use, the meanings are compared with other publications. This article determines which maritime terms can be considered as neologisms proposed by V. Pakalniškis and partially discusses the (un)suitability of these proposed terms.
