    Yes, I am a mechanical engineer and also inventor specializing in jet engines. Thank you.

    As for the cart, it started with all the canvas extra sides and bottom with braces. I removed all of the non needed braces ( cut them with a hacksaw ). Now it is folding up nicely with minimum weight. I added foam pads on the bottom to support any of my boats. I then decided to also include the separate PVC pipe cradle. Now , I can load the boat at my car ( SUV ), place the cradle on the cart, and then the boat on the cradle. I now can drive it on the pavement all the way to the dock. I can also drive it on the grass to ponds that do not have a dock.

    All fun๐Ÿ˜Ž๐Ÿ˜Ž๐Ÿ˜Ž

    This huge 6.5 ft long boat is now fully operational. But I have no room for it inside the house. It was just taking valuable table space in the garage.

    I decided to build a shelf for it on the garage side wall ( concrete blocks ).

    Now this big boat has a proper place in between missions

    Now that the old torpedo boat is operational and running fine, I was asked to do a short Show and Tell about it. I will present it to a club in the Sarasota ( Florida ) area soon.

    I wish I knew the original builder's story. There must be at least some hundreds of hours worth of build here.

    I just repaired it and made it sea worthy again.

    Picture is from the original owner. ( the submarine in the back was sold to a collector in Texas ).

    My main problem with this big and heavy boat is to lower it to the water.

    I could not do it from the dock because there is a drop to the water. So I had to find a shallow area at the pond that I can lower the boat. That was a pain in the butt.

    One of the fellows showed me his sail boat cradle. I liked it, but had to make an engineering modification to lift the big boat.


    Here is my solution made out of 1 inch diameter PVC plastic pipes o got at the local hardware store.

    Iโ€™ll test it soon

    I have yet to try my cradle. I think it is too long. I may need to cut it to make it shorter as none of the docks here are that deep.


    currently each segment is 2 ft long ( total height is about 4.5 feet including the fittings ).

    I find that cradles are good for one type of dock or another. The ones I have experiences have no flat sides to lean against while retrieving the boat.

    As fo my version, I found it is too big and to buoyant. Will need modifications.

    Lew, I looked at the metal cradle with interest. I wonder if the addition of 2 wheels at the bottom of the cradle were the vertical lift arms meet the cradle would help to make it easier to remove the boat from the water at a location that has a deep bulkhead. It would allow you to slid the unit along the bulkhead as you lift and take some of the strain off your back. Len

    Isaac, the length of the metal cradle is a little short for launching off a dock like ours. However, it is the right length for transporting when using it like luggage.

    Thank you Lew and Hermank for your suggestions. ๐Ÿ‘๐Ÿ‘๐Ÿ‘

    I do like the metal cradle, but it is similar to the PVC version. But the metal one looks sturdy for sure.๐Ÿ˜Ž



    I just tested my contraption at my pond off shore, and found the silly noodles are very buoyant and I had to push it down into the water. The metal ones probably would sink more and be better suited. But I do not have welding equipment and also wanted something longer.


    I am yet to test it off a dock, but plan to doing soon.

    Jim, a fellow member of the SSMBC, designed a strong cradle for model boats several years ago. It was liked by so many other members they have had Jim make more for them. Each has their own way of installing the protective foam.

    In addition to the photos, here are some of the specifics: Tubing is 1/2 inch EMT conduit (steel tube used in building wiring). Bent and welded. Handle is located over the lateral CG. Sits low to the ground. The best I have seen yet!

    Enjoy.

    I did think of something simple, but this is such a big and heavy boat, that I needed something more solid than ropes or straps. Also, it should be easier to get the boat to be retrieved.

    I just got two new batteries; ๐Ÿ‘LiPo 3S thatโ€™s 11.1 volts at 5,200 mAh each. Coupled in parallel to keep the voltage. At 11.1 nominal. Ran the boat at medium speed for 15 minutes. Batteries check at 74 percent still available. That means I can comfortably run for 30 minutes with reserve. Thatโ€™s more than enough for me.

    This boat lives this amount of power.

    Hi Isaac.

    I like seeing your model's navigation but you give us very few seconds of video.
    Well today a little better, 18 seconds, ahahahahah.

    It's true, you're right, the speed is higher than the scale speed, but if you were at full throttle and want to make a more realistic demonstration video you can make it go at idle.
    So that's more than fine.

    I also prefer to have the possibility of a little more sprint if needed.
    The important thing is how it is in the water.
    Boats that are too light are pushed by the waves in a completely artificial way (apart from the speed issue), however your RC model gives a good impression.
    I also like it in turns.

    The old torpedo boat is finally ready. All the wiring and controls are working and Iโ€™m using my aircraft Spektrum radio.

    All three motors are are joined and operate via a single throttle.

    Currently I coupled two LiPo 2S 7.4 volts at 5200 mAh each running in parallel. Not bad, but I ordered 3S batteries and see if the old boat can handle it.

    So now that we know that the torpedo boat died in the water due to transmitter issues, it was still stranded in the middle of the pond. I had to retrieve it.


    not a problem, I have multiple boats to rescue it.

    So my wife said, ๐Ÿ‘ "use the tug boat" to push it to shore. I said, let me use the large shrimp fishing boat and drag a long rope behind it and then snag the old torpedo boat to bring it in. ๐Ÿคž


    so....

    After a couple of turns around the torpedo boat, the fishing boat died and would not move. The rope snagged the fishing boat propeller and now I had two dead boats in the water. ๐Ÿ˜ ๐Ÿ˜ ๐Ÿ˜ 

    frustrating.


    My wife was right, I got the tug boat ready.

    Sure enough, I ran it to the torpedo boat and within a few minutes, I pushed it to the shore. Yey....rescue number one๐Ÿ‘๐Ÿ˜Ž


    Now it was time to rescue the fishing boat.


    So I head the tug to the fishing boat and started to push it. However, within a few seconds it to stopped and somehow got snagged by the rope from the fishing boat. Oops, I now had a third boat dead in the water. Not good.

    I was thinking of sending another boat out there to rescue the two tangled boats, but decided against it for fear of losing it as well.

    As it turned out the winds and waves cooperated and the tangled mess of the boats made it to shore after 30 minutes or so๐Ÿ˜”๐Ÿ˜๐Ÿ™„๐Ÿ™„๐Ÿ™„.

    When I pulled one boat out of the water, the other one pulled as well. Both props were a tangled to each other.


    Moral of the story : listen to your wife!!!!!!!!!!๐Ÿ‘๐Ÿ˜Ž๐Ÿ˜

    and that is no fish story!

    The air boat or a dedicated rescue boat is always a good idea. Normally, my sailboat friends always have one to retrieve their often stranded boats.

    Since I am also an RC model plane flyer/builder, I do have spare parts to make an airboat.

    I like this simple concept in the attached picture. A flat foamboard with bumpers. It is better for my large boats than the scooping arms suitable for smaller boats.


    Thank you

    Or use an airboat for rescues like I do, no risk of tangles. I always chuck mine in the car just in case,- don't want to go swimming in a drainage pond, -never know where it's been ๐Ÿ˜ A jet rescue boat could be handy as well, but an airboat is uncomplicated.

    I finally got the original Ace radio to work with the boat.

    After running the boat for close to 15 minutes, the boat stopped dead. The transmitter external battery was hot and I disconnected it from the transmitter.

    Root cause was multiple internal locations where the insulation was frayed, but it was really mostly my fault.

    A bit of background information:
    I replaced the original dead battery ( which was not original since it looked like it was replaced and rewired internally with different connectors ). But, I wanted the battery pack to be outside the transmitter case so I can easily charge it. That was a good idea. However, I should have made a cut out for the wires leading out of the metal transmitter case.โ˜น๏ธ The wires got pinched when I closed the back of the transmitter, cut thru the insulation and shorted the battery. Oy...๐Ÿ˜ฎ

    See photos.

    It is all repairable though.๐Ÿ‘


    to be continued.................
