    That is talking about on a road, I am talking about on waste ground riverbanks etc

    anyway these are not big issues far more important are things like the shape of the bow, the design of the entrance and finishing her off things

    It may tow a little wagon with 5 kg in it, but there is no way it will pull your fantasy boat from the water.

    In the UK there are no wastelands; they all have owners.

    Worse than that, I'm pretty sure that when you hit the trigger-throttle on that thing, it will immediately perform a violent wheelie and throw you on your back, and maybe land on top of you as well. Send us a card when you're in the hospital--if anyone finds you soon enough.

    There is a lot of wasteland near river banks and most of the uk is forest and woodlands

    this is gods creation for humans t enjoy and I do

    my tiny house boats are designed to live near river banks and forest areas where there is lots of wood for the stove

    No I will pull her out of the water by hand but yes the twin motor wolf electric scooter is designed to tow loads in the low geared very slow mode

    It’s twin motor so no wheelies the drive is in the front wheel

    it can take two adults uphill at speed

    I’m talking about less weight than that at low low speed

    it sounds like those comments about the scooter know very very little about the next generation electric scooter but that is fair enough as this is a boat design forum

    for get the scooter towing that is not important let’s get back to the boat design

    I will be releasing detailed plans and a complete project plan behind a paywall

    I will also be writing another book for sale on Amazon with all the details of the project and other similar projects

    after this one I’m working on a smaller one man craft that will be super super lightweight built similar design but half the size and less than half the weight as using plastic panels instead of steal. They will be also sandwiched between plastic wrap and expanding foam filled

    You put the scooter as part of the design requirements. If you take it out, the design will develop in a different direction. However, the most important part, your materials and building techniques, are full of flaws. As far as not knowing, I am a mechanical engineer and worked over four years in battery research and electric vehicles.

    I looked at the website. It drives both wheels, but it seems to be capable of using only one, which I assume would be the rear.

    But tell me about this trailer hitch that you say you have on this scooter. I've found nothing to indicate that the manufacturer offers that as an accessory, and the owner's manual probably tells you not to, though I couldn't find a way to download a copy of it to be sure. I'm guessing you attached it to that curved bar above the rear wheel, right?

    The scooter is not important as I keep saying, it will be mostly moved by hand either floating or on wheels

    getting the design right to have all those list of requirements is the hard part

    here are my inspirations something along these lines

    Your target of 70kg is not reasonable. The only vessel you have pictured that is in that range is the canoe in the foreground. All of the actualized vessels are closer to 7000kg than 70!

    If you stood near the edge of a 2meter wide float of 70kg, it will roll over. The only way your 2x2x3.5 meter box will remain up right is with thousands of kilos of ballast.

    Nah. This Wavewalk 700 weighs 80 lbs bare and is only 31" total width. Scroll down to the first video, with the guy standing with both feet on one side and paddling. Yeah, he's using some body English to lean toward its center; still. Wavewalk® 700 Solo & Tandem Catamaran Kayak – Wavewalk® Stable Kayaks and Microskiffs https://wavewalk.com/blog/new-700-series/

    None of those little trailer-floaters weigh anything close to 7000kg either, probably less than a tenth of that.

    Otherwise, I agree; he's not going to get anywhere close to his target weight in that size (and I believe he spec'd the dimensions as 2.5 x 2.5 x 4 meters); it's going to roll and pitch a little with the smallest waves, and it will roll significantly when he gets off-center. Depends on the hull shape, too; I think I've seen pontoon party boats about that size, and I don't think they're particularly dangerous. I sure wouldn't want to try to heat up a pot of soup or drink a cup of coffee aboard one, though.
