This is a photograph of Poseidon Express entering the port at the Greek Island of Paros, taken on 10 Sept 1994. She operated a very fast service from Piraeus to Santorini, and was a very popular ship with passengers.

In this image you can see the speed at which she is entering very confined waters. On 20 April 1996, she struck rocks in this harbour and sank, thankfully with no loss of life. See this super link for more details:

She started life in 1974 as Provence for French operators.
