That is definitely a 474 Freestyle. It is a great 15 foot beachcat.

Mine still has some original logo on it. It says was manugfactured by Boston Whaler in 1979.

The pic of the guy and the red spinnaker lives in Vancouver, BC.

The boat eventually snapped in half at the front beam, flying that masthead spinnaker.

He may have been OK had he installed a spreader at the bows.

Not doing so did provide a mast for me to get my boat going again after we folded the mast, flying a hull with four adults on it.

Needless to say, that wasn't what the boat was designed for.
