Behold the 'Tinytanic' - The World's Smallest Houseboat
Forget about 'footitus,' maybe 28 square feet is all you need.
That's according to YouTuber David Rule, who built a houseboat measuring a meager eight feet long and 3.5 feet wide, yet somehow manages to squeeze in a bed, kitchen, refrigerator, and complete solar-powered electrical system. The vessel, the perfectly felicitous Tinytanic, manages to incorporate the full living accommodations of a cruiser or small yacht, yet is somehow small enough to fit inside the bed of a pickup truck.
Rule documented the entire project on his YouTube channel, which has predictably gone viral after viewers were enchanted by the sheer capability packed into a vessel that wouldn't even qualify as a tender for a cabin cruiser.
Rule's journey began with a small set of pontoons and a basic wooden framework. From there, he fitted a cedar 'cabin' on top, added an electric trolling motor at the stern, and assembled a pair of solar panels on the roof. Despite its small size, light weight, and low power needs, the Tinytanic is surprisingly capable. As long as the waves aren't too big.
Rule says the project was inspired by fellow YouTuber Zach Fowler, who ironically BoatBlurb covered back in 2024, and who happens to be a winner of Discovery Channel's Alone series, meaning he knows how to make a seaworthy vessel. Fowler made his own miniature houseboat - at a cavernous 35 square feet compared to Rule's built specifically for lobster fishing - and spent a full four days at sea while sleeping, fishing, and cooking onboard.
Rule took Fowler's concept even further to break his record, somehow reducing the living space to 28 square feet and bringing the LOA down to 8 feet from Fowler's superyacht-like 10.
It's also quite a head turner.
The Tinytanic is built mainly of cedar, pine, and a little plywood, with a cedar platform supported by the pontoons and an aluminum roof. The boat features surprisingly large windows, including a bay window covering the entire bow-facing section, which provides natural sunlight at nearly water-level views. There's even a ritzy brass nameplate for Tinytanic above it. It's worth noting that The YouTuber previously built a floating hot tub on his channel, which included him some valuable lessons about how to maximize the capability of a modified seafaring vessel.
Inside, the available space is divided between a sleeping area and a small kitchen counter. The cabin itself is about 42" high, just over three feet, meaning Rule or any guests have to sit or lie down rather than stand, but with the huge bay window at the bow, sitting down to eat includes a picturesque view. Out on the deck, two small platforms on either side of the tiller give the captain enough space, and the view, to feel like they're at the helm of the Black Pearl rather than the world's tiniest houseboat.
For long days at sea, the Tinytanic's kitchen even includes a sink, small refrigerator, and a single-burner butane stove. A 12-volt pump supplies water to the sink, while wastewater is collected into a container below. A fan helps circulate air through the cabin, and a zippered tent-style panel at the rear can be opened to provide additional airflow.
Power comes from two 100-watt solar panels mounted on the roof, which charge a 100-amp-hour marine lithium battery. The system supplies electricity to the boat's onboard equipment, including its ventilation system and charging outlets.
For propulsion, Rule installed an electric Minn Kota trolling motor with 30 pounds of thrust. Mounted at the stern on custom wooden brackets, the motor offers enough juice to get the vessel from Point A to Point B under fair conditions.
Rule took the Tinytanic on its maiden voyage along Washington's Pend Oreille River - a 12-mile trip from Metaline Falls to Peewee Falls. The limited onboard battery power the sticking point during the journey, caused mainly by the constant engine power required to push Tinytanic up the river paired with the overcast weather in Washington state, which forced Rule to conserve energy and use the motor sparingly.
As you'll see from his adventure, being forced to 'dock' the Tinytanic along the picturesque river hardly seemed like a disappointment.
