What started as a dream sail around Ibiza and Formentera quickly turned into every sailor’s nightmare… After unknowingly filling up with contaminated diesel, one of the engines on our Lagoon 450 catamaran became increasingly unreliable. Every time we had to start the engine, we wondered:
Will it start… or won’t it?
In this episode we take you along as we explore the stunning Balearic Islands while dealing with unexpected engine failures, searching for the cause, and trying to stay safe with only one reliable engine. You’ll discover beautiful anchorages, hidden beaches, the famous hippie markets of Ibiza, family life on board with our kids and dog Ollie, and what life is really like when technical problems interrupt your sailing adventure.
