20 Dec 1978. Tourist Boat sinks close to Fuerteventura.
The tourist boat “Poseidon” sunk on its way back to Lanzarote, overwhelmed by high waves due to stormy conditions. The boat carried 30 passengers and 2 crew members; only 21 survived.
The tourists were returning from a one-day visit on Fuerteventura. Weather conditions were bad and wind gusts of 7 Beaufort were hitting the sea. Upon their way back the rudder broke due to an overload of high waves and shortly after that a stern wave capsized the 15ton vessel (see picture). As the security measures failed, all passengers had to swim for about 3 km to the shore. Many of the survivors suffered injuries.
