It is always a great advantage if a yacht  crew member can speak more than one language, but in reality, everyone who works as a crew on a yacht is bilingual, without even knowing it. “Yacht speak” even though it’s the unofficial term, it is a completely different language that you need to learn before you step your foot on board. If you’re interested in finding a job in a yachting industry, save this guide for later. I promise it might come handy one day.
