Did a freak wave cause tragedy?

Investigators think a freak wave may have caused Sunday's tragedy at Coonanna Harbour near Cahersiveen in which three Latvian friends lost their lives while on a fishing trip.

Anatolijs Teivens (57), Valerijs Klimentengvs (38) and Jurijs Burcves (30) died in the boating tragedy when the small boat they were fishing from apparently capsized.

While there was a strong two metre swell outside the harbour, local residents said the conditions in the harbour were relatively calm.

There were, however, strong force three to four north westerly winds which have, on occasion, been known to cause dangerous 'freak' waves around the harbour mouth.

While the exact cause of the tragedy is still unclear, investigators believe that such a wave, coupled with the design of the men's boat - a light fibreglass speedboat with a large engine - could have played a part.
