I recall watching a movie multiole times in my childhoof in the 80s. Now I’m pretty sure the movie is a late 60s or 70s film. It was in English. There were 3 or 4 children/teen primary characters. One of them was an older boy named “Spider”. I recall a few different scenes of them in a boat with an outboard engine, as well as what I think was a tower on an island…but I’m a bit hazy from there on out.

Thanks!
