Do you know this movie?

A blog visitor contacted me and asked for a movie title. Perhaps someone knows the movie title to this description?

“I’m looking for the name of a movie where a guy with no equipment in a large pool drowned some divers. The movie was from the 60’s or 70’s. I don’t think the women were there, but the action was fun. Do you know anything?”

Would be great if someone would know the title…
