Учитывая, что термин в США применяется в контексте буксирных судов, т.е. равнозначен tug master. По-русски "рейсовый капитан" практически не встречается и имеет несколько иное значение, а "капитан" буксира как раз именуется шкипером, насколько я поняла из ссылок, так что думаю, что "шкипер" тут будет в самый раз.

Не знаю, позволяет ли контекст, но, возможно, "назначенный шкипер".

English term (edited): trip pilot

A maritime pilot, marine pilot, harbor pilot, bar pilot, or simply pilot, is a sailor who maneuvers ships through dangerous or congested waters, such as harbors or river mouths. They are navigational experts possessing knowledge of the particular waterway such as its depth, currents, and hazards.

The word pilot probably came from Middle French pilot, pillot, from Italian pilota, from Late Latin pillottus; perhaps ultimately from Ancient Greek πηδόν (pēdón, "blade of an oar, oar").

The work functions of the pilot go back to Ancient Greece and Roman times, when locally experienced harbour captains, mainly local fishermen, were employed by incoming ships' captains to bring their trading vessels into port safely. Eventually, because the act of pilotage needed to be regulated and to ensure that pilots had adequate insurance, the harbours licensed pilots.

Before harbour boards were established, pilots known as hobblers would compete with one another. The first to reach an incoming ship would navigate it to the docks and receive payment. In Dún Laoghaire, Ireland, there is a monument to the hobblers who lost their lives. In Kent they were known as "hovellers" and worked alongside and in competition with the licensed pilots, but were sometimes blamed as wreckers. George Byng Gattie defends the hovellers or "hobilers" as lifesavers in his 1890 book about the Goodwin Sands.

Pilots had to have quick transport to get from the port to the incoming ships. They initially used their own fishing boats to reach the incoming vessels, but these were heavy working boats, which led to the development of the specialised pilot boat.

In the inland brown water trade another type of pilots are known as trip pilots.
