When a solar-powered wooden houseboat was found washed up on an Irish beach, locals were puzzled.

Three years later, they have finally got to the bottom of the strange vessel's origins -- and traced the boat's original owner almost 2,000 miles (3,200 kilometers) across the Atlantic, to Newfoundland, Canada.

The mystery began in 2016 when a local in County Mayo, western Ireland, discovered the boat on the beach at night. "We had received a call from a member of the public to say that a caravan type vessel had been washed ashore on the west side of the Mullet peninsula, near Drum beach," Michael Hurst, officer in charge at Ballyglass Coast Guard Unit told CNN.

Linda O'Leary had alcohol on breath on night of fatal boat crash, warrant documents say

Linda O'Leary, wife of entrepreneur and media personality Kevin O'Leary, had alcohol on her breath following a fatal crash involving a boat she was driving in cottage country north of Toronto last summer, according to recently unsealed search warrant documents obtained by CBC News. "Mrs. O'Leary was administered an alcohol screening device test and registered an alert. She was subsequently served a three-day driver's licence suspension," Ontario Provincial Police allege in the documents. "Mrs. O'Leary claims to have consumed a drink of vodka following the collision and prior to the breath test.

The "contraption," Hurst said, was made of wood and was kitted out with solar panels and kettles.

"It looked a little bit like a caravan. In the water, it seemed just a strange looking object really," Hurst said.

Even more mysteriously, a message was written within the vessel: "I, Rick Small, donate this structure to a homeless youth. To give them a better life that Newfoundlanders chose not to do! No rent no mortgage no hydro."

After checking no one was aboard the vessel, Hurst posted about the boat to Facebook. By the next day he was inundated with calls from local media, and was contacted by many interested and puzzled locals.

"There was a lot of interest in it, something strange like that coming up on the shore," he told CNN.

After no one claimed the boat, and with Rick Small nowhere to be found, members of the coast guard unit and the local community refurbished the vessel and donated it to a community sensory garden in nearby Binghamstown.

A 19th-Century Lighthouse With Prime Views of Key West Could Be Yours

The screw pile lighthouse in Key West, Florida, was built to withstand the hurricanes that regularly batter the region.Old lighthouses around the world are available to rent on a nightly basis, and if you're looking for a more permanent situation, it's not too difficult to find lighthouses for sale in the United States. As Atlas Obscura reports, one 19th-century structure currently being auctioned off by the U.S. government offers stunning views of Key West, Florida, and a level of isolation usually limited to private islands.

The origins of the vessel remained a mystery for three years, Hurst said, until he received a message on Thursday from a journalist who told him he had solved the puzzle once and for all. The owner of the abandoned boat, according to Canadian Broadcaster CTV, is 62-year-old inventor Rick Small.

In an interview with CTV, Small, said that he built the solar boat to raise awareness of climate change.

"[I was going to] go from Newfoundland around the Arctic to here in the summer," Small, who has also invented solar-powered bikes, told CTV. "To show that the ice is disappearing."

Unable to find the correct motor for his trip, Small told CTV he gave the boat away in Newfoundland, and had no idea how it made its way across the Atlantic.

"It didn't sink," Small told CTV. "I must have done a good job, eh?"
