Helicopter Rescue As Boat Sinks

I've left out the first word as it's not really relevant...

Sky News

Finally a helicopter was called into action by authorities in Zagreb - but as a rescuer was winched down Mr Plevnik refused to abandon his boat.

It was only when water splashed over the side and the vessel quickly began to be sucked beneath the surface that the rescuer was able to pull the skipper to safety.

It was probably the downwash of the helicopter that caused the water to start lapping over the sides, into the boat which caused it to sink!

Doubt it.. downwash normally settles a body of water beneath it than causing waves

The boat look fairly steady until Harold the Helicopter arrived!

The downwash from the helicopter pushed the boat into the water, rather than forcing the the water over the gunnels.

I must admit, that is how it looked to me too.
