They say the two best days of a boat owner’s life are the day that they buy the boat and the day they sell it. If you built your boat from scratch though, you might have a few more good days than that. [Paul] at [ElkinsDIY] is no stranger to building boats, but his other creations are a little too heavy for him to easily lift, so his latest is a fully electric, handmade boat that comes in at under 30 pounds and is sure to provide him with many more great days.
While the weight of the boat itself is an improvement over his older designs, this doesn’t include the weight of the batteries and the motor. To increase buoyancy to float this extra weight he made the boat slightly longer. A tiller provides steering and a trolling motor is used for propulsion. As of this video, the boat has a slight leak, but [Paul] plans to shore this up as he hammers out the kinks.
The boat is very manageable for one person and looks like a blast for cruising around the local lakes. Since it’s built with common tools and materials virtually anyone should be able to build something similar, even if you don’t have this specific type of plastic on hand. And, while this one might not do well in heavy wind or seas, it’s possible to build a small one-person boat that can cross entire oceans.

[Rinoa Super-Genius] shows us in a video how to build a crude motorized barrel boat using only a few parts, including pontoons for extra buoyancy and stabilisation.
Building a barrel boat is simple. All you really need is a plastic barrel, scrap wood, PVC pipe with end caps, a battery, and a trolling motor. Of course, you could go even further and build your own trolling motor too.
The video shows the process of building the boat. You start of by cutting the barrel in two, making some calculations of water displacement in order to add the pontoons in the correct positions. These are just held in place with scrap wood screwed into the barrel. Connect the trolling motor to a battery and you’re done.
This isn’t obviously the best looking DIY boat out there, nor does it claim to be, but it can be built on a tight budget. If you have the right parts lying around, you could even build it for free.

The odds are that many of you do not own a boat that you get to tinker around with. [Mavromatic] recently acquired one that had — much to his consternation — analog gauges. So in order to get his ship ship-shape, he built himself a custom digital gauge to monitor his vessel’s data.
Restricted to the two-inch hole in his boat’s helm, trawling the web for displays turned up a 1.38-inch LCD display from 4D Systems. Given the confined space, a Teensy 3.2 proved to be trim enough to fit inside the confined space alongside a custom circuit board — the latter of which includes some backup circuits if [mavromatic] ever wanted to revert to an analog gauge.
Two days of acclimatization to the display’s IDE and he had enough code to produce a functional display right when the parts arrived.

As the human population continues to rise and the amount of industry increases, almost no part of the globe feels the burdens of this activity more than the oceans. Whether it’s temperature change, oxygen or carbon dioxide content, or other characteristics, the study of the oceans will continue to be an ongoing scientific endeavor. The one main issue, though, is just how big the oceans really are. To study them in-depth will require robots, and for that reason [Mike] has created an autonomous boat.
This boat is designed to be 3D printed in sections, making it easily achievable for anyone with access to a normal-sized printer. The boat uses the uses the APM autopilot system and Rover firmware making it completely autonomous. Waypoints can be programmed in, and the boat will putter along to its next destination and perform whatever tasks it has been instructed. The computer is based on an ESP module, and the vessel has a generously sized payload bay.
While the size of the boat probably limits its ability to cross the Pacific anytime soon, it’s a good platform for other bodies of water and potentially a building block for larger ocean-worthy ships that might have an amateur community behind them in the future. In fact, non-powered vessels that sail the high seas are already a reality.

Last year we wrote about Hackerbot Labs’ autonomous boat, which project members hope to someday circumnavigate the globe. Now called Project Ladon, progress continues apace with a recent ocean test of their modified 18’ kayak, the TSV Disputed Right of Way. The kayak’s internal spaces contain a pair of lead-acid truck batteries controlled by a home-brewed control system that uses relays to control the craft’s trolling motor, with a Beaglebone and Arduino Mega under the hood.
The test was not exactly a success, with the boat actually avoiding the waypoints rather than sticking to them. Fortunately the team was aboard a chase boat so they were able to keep tabs on the craft. Unlike a quadcopter, which just falls down, a watercraft that borks may never be seen again.
Entered into the 2016 Hackaday Prize, the project has continued to gather steam, with presentations at both Toorcamp and Maker Faire Bay Area. In addition, they’re maintaining their Hackaday.io project site as well as a Patreon page.
Check out a couple of videos after the break! The test video is 360-degrees so you can drag around the POV.

In the world of sailing, there are many records to compete over. Speed records, endurance records, size records. The fastest crossing, the longest solo journey, the largest yacht.
But not all records concern superlatives, for example in the size stakes, there are also records for the smallest vessels. The Atlantic crossing has been completed by a succession of ever smaller boats over the years, and the current record from 1993 is held by the 5’4″ (1.626m) boat Father’s Day.
Records are made to be broken, and there is now a challenger to the crown in the form of the impossibly tiny 42″ (1.067m) Undaunted, the creation of [Matt Kent], who intends to sail the boat from the Canary Islands to the USA in around 4 months.
The boat’s design is definitely unusual, with a square aluminium hull of equal beam and length, and a very deep keel that has an emergency drinking water tank as its ballast. The sail is a square rig — imagine picture-book images of Viking ships for a minute — and it has two rudders. We are not nautical engineers here at Hackaday, but reading the descriptions of the boat we understand it to have more in common with a buoy in the way it handles than it does with a sleek racing yacht.
Unfortunately the first sailing attempt suffered a setback due to a design flaw in the way the vessel’s emergency flotation is attached. This was revealed by its interaction with some unusual waves. But [Matt] will be back for another try, and with luck we’ll see him on our TV screens sometime next year as he emerges into the Florida sunshine from his cramped quarters. Meanwhile his unusual boat and its construction makes for a fascinating read that we’re sure you’ll appreciate.
We don’t often cover boat building here at Hackaday. But if unusual ocean crossings are of interest, here’s an autonomous one we looked at back in 2010.

There is something about a wooden boat that should be facsinating to most makers, the craftsmanship and level of work that goes into creating a sea-, lake-, or river-worthy craft with smooth lines, from little more than thin pieces of wood. Master boatbuilders have apprenticeships that last years, and spend entire careers refining their art.
[Adam], also known as [A Guy Doing Stuff], is not a master boatbuilder. In his words, he’s just a guy with some basic woodworking knowledge, who builds canoes from cedar strips. But you wouldn’t know that he has no training as a boatbuilder from looking at his work, which you can do because he’s posted some beauthiful videos.
We see the creation of a skeleton to produce the basic shape of the boat, followed by the creation of prow and stern. Then there is a painstaking application of carefully shaped cedar strips to make the hull, and a single layer of glass fibre on either side. With the gel coat applied though you wouldn’t know the fibre was there. Finally we have the creation of the seats and interior fittings, followed by the canoe being paddled across a lake.
Few of us may ever make a canoe. But if we did, we’d want it to be one like this one.
