I saw it a looooong time ago, so I'll do my best to supply as many pieces as I can: 1) It involves some boys trying to solve some sort of crime in a coastal town. 2) There's a crazy beatnik-type character who lives on a boat and his name was something weird like "Clutch" (or something. Can't remember if he's a villain or not. 3) Lots of action takes place on a marina/docks 4) Not 100% sure if it was a Disney effort, but it certainly looked like one. Light-hearted. Perhaps even made for TV? I know this isn't much to go on, but I can't seem to find anything out there and I'm hoping this will ring a bell with someone else. It's been driving me nuts for years.
