Robert Morse, Stefanie Powers & Phil Silvers in The Boatniks (1970)
Disney made a lot of live action, family oriented films in the 60's and 70's. Many of them became quite well know, or are at least somewhat remembered. This is not one of those. The Boatniks is set in Balboa Bay in Southern California - a very popular boating hub where mishaps frequently happen because of the traffic. That chaos is a big part of the plot, which has several sub-plots, including romance between a green harbor master (Morse) and the owner of the local rent-a-boat operation (Powers), and the attempted dash to Mexico by a group of inept jewel thieves (Silvers, Norman Fell and Mickey Shaughnessy).
Though not exactly memorable (while watching the film again I had distinct sense memories, though had totally forgotten having seen it as a child) it is a pleasant diversion and it's fun to pick out the popular character actors. Look for Don Ameche as Morse's boss, Wally Cox as a libidinous harbor resident always surrounded by a gaggle of gorgeous girls and Joe E. (Ooh! ooh!) Ross as a hapless boat pilot.
The Boatniks is available on DVD. Above is the trailer for the film, uploaded to YouTube by TheCinemastudio.
