TTesting a Laser-Cut Mini Boat!

Published on Feb 22, 2018

We meet Josh Tulberg, an industrial designer who fabricated a mini boat of his own design, using his workshop laser cutter and 3D printer. Josh shows us how his boat kit is put together using zip ties and epoxy, and we take his boat on the water to test its seaworthiness. And it surpassed all of our expectations!

Find out more about Josh's Mini Boat kits here:

    needs a solar panel bimini and regulator, did it to my dinghy (on my channel), it eliminates range anxiety

    I got an ad for a Yanmar X39 I'd honestly rather have this tiny thing

    Don't waste your money on marine ply, use exterior ply, it uses the same glue and meets the same basic standards as marine ply and costs only 1/4 as much

    Looks like Berkeley aquatic park near the Bay bridge where they are testing the boat. Cool boat

    How much did the boat cost to make?

    How many times you going to ask the same question you fucking douche

    +Tested yes I like it.... BUT, imagine near the same at 7ft length, with a 55-60 lb thrust trolling motor (about max for 12v) and the right prop for doing it, with a skimmer+foil up front and a hydrofoil to lift it 3-4" off the water to do 8-10 mph. entirely possible, it'd still fit into the back of a small pickup truck or station wagon, able to cover 3-4x the distance, and at a good clip! there would be some slightly hectic math and designing involved for the skimmer and front foil, the main foil, and for the 3D printed prop to deliver the needed thrust+speed without killing the trolling motor during it's burst demand current (WOT for 10-15 seconds?), but once it lifted the surface area drag and amp demand both drop out drastically. now imagine the reaction to it by onlookers seeing it near silently "flying" along at 8-10mph...

    Too bad in the state of Commiefornia where these boats were being used ANY boat with a motor has to be registered. Good job spoiling the fun and smashing the dreams for all those young kids inspired to tinker in the garage and build something with a motor. The looney liberal leftie socialist government in California is great at ruining peoples lives and spoiling the adventure and fun of most activities.

    all you need now is pedals underneath, with a chain sprocket setup like on bikes, to drive a charging motor.

    Where can I get that sketch of the person in solid works?

  • Sun Tzu - 4 days ago

    I was genuinely surprised to see the price at only $950 for the kit, I thought for sure it'd be like all those other cool little kit-vehicles on the internet that end up costing tens of thousands of dollars to make.

    Hey, really nice video, but that isn't really the case why I'm commenting. I wanted to share this indiegogo campaing started by 16 yo, who's dream is to build a small boat out of plywood so he could cruise around with his family, because now they are having some problems with relationships with each other. Please check it out and help him. This is the link

    Don't let the DMV see this. "...every motor-driven vessel (regardless of length) that is not documented by the U.S. Coast Guard which is used or on the waters of this state are subject to registration by the Department of Motor Vehicles (DMV)."

    That's really cool, love it!

    This is awesome, tbh tho if you do a v2 id like to see a way to erect a mast and sail, like of the mast could fold down just not sure how one could erect it sitting, or would have to make it stationary

    Stitch and glue, a new technology?? you been living under a rock dude??? I was building sailing dinghy's the same way 40 years became commonplace in the early 1960's but the basic method goes back to 2000+BC. You Americans only discovered it in the late 60's. Like they say Everything Old is NEW again, 2 generations later.

    I'd like to see what he could build thinking like a jon boat size.
