    That's a good thought, sbk.

    If the boat is on a track - then brakes makes sense

    Re: Old Jungle Cruise boat design question

    I think sbk1234 might be right. Based on Steve's posted video, I will vote brake too.

    The boat comes up to the boat and the skipper does something to that lever. I would guess it's to hold the boat in place as people unload or load.

    Either that or it locks something to the track so the boat doesn't rock as much as people load/unload.

    Hmmmmm... Having a "Parking Brake" of sorts rigged to the guide rails at the dock would be an interesting idea - till it breaks, and you have to pull the boat out and fix it. Over, and over, and over, and over.... Nevermind, have the Unload CM's hold it in place.

    My first thought was it's the thrust reverser or "reverse gear" on the early boats. They may not have had the "unified control binnacle" when the JC boats were first built in 1954 - especially if the first generation were built with propellers & a gearbox and not jet drives.

    The current engine control binnacle lever does Two things inside with cams and levers, they throttle up the engine going either way from 'Neutral, and they shift the thrust reverser bucket in front of the jet pump nozzle for reverse.

    And a quick search about Jacuzzi Brothers Inc. Jet Drives got me absolutely nowhere on a timeline - It hints at "became popular in the 1960's", which might mean the boats started out with regular propellers.

    Okay, time to ask someone who knows - {ahem! Check One...} <CLICK> "Paging Bob Gurr, Please pick up the White Courtesy Phone. Robert Gurr, Please call the Disneyland Operator."

    Maybe that's the signal for "Riverboat, ring your bell."

    Ummm... current boats, aside from the CNG conversion, are still straight 4's with a prop shaft. I used to have pictures of them when they were lifted out, and I've helped on them enough to know the setup. I also confirmed years ago that the straight 4 has always been the boat setup, and that the forward/reverse itself has never changed. However I have yet to see a video of early boats backing up so I am unable to confirm that first hand. I know the physical boats today are bigger then the early boats. This is why 2 boats were removed and partially why the speed is slower. There is a governor that prevents higher speeds on the new models, but the old boats were also faster due to being overall smaller and lighter.

    Steve... if this is indeed a brake system the immediate followup (which may not have an answer readily available) is why was it removed? As a former Skip who witnessed first hand the perils of "docking" I would think a brake system would be mandated on the boats. I've seen plenty of incidents at both load and unload caused in part by inexperienced Skips trying to dock.

    Spin off question: do you know any more about the context of the James Garner photo?
