I am trying to find Title and other information on a surfing movie from 1960's or 1970's. It was set in Hawaii and features several friends from US Mainland who go to Hawaii to surf for the Summer. One of the guys falls in love with a native Hawaiian girl. Her brother is opposed to this and ends up getting in a fight. As they fight they fall into a car and the brother ends up falling over a cliff. At end of movie the surf is really rough and as they surf one of them almost drowns but is rescued by his friends. Great soundtrack. Any info would be helpful. I thought it was "Endless Summer" but cannot find anything by that title.
Thanks,
Ed

Since you said in was in the '60s or 70s, it could be:

Ride the Wild Surf (1964) - Plot summary (http://www.imdb.com/title/tt0058523/plotsummary)

But it actually sounds more like the one below, from your
Description:

North Shore (1987) - Plot summary (http://www.imdb.com/title/tt0093648/plotsummary)

Definitely isn't North Shore. I've seen that movie more times then I care to remember.

Thank you both very much.
Ed

Neither of these are the movie but thanks for your help.

Could be "big wednesday"
