History of Pontoon Boats: From Barrels to Luxury

The history of pontoon boats starts with a Minnesota farmer, a pile of empty steel barrels and a problem: the fishing boats of 1950 were narrow, tippy and built for two. Ambrose Weeres of Richmond, Minnesota, wanted a stable platform that could carry his whole family. His answer — a plywood deck across two columns of welded steel drums — became the modern pontoon boat. Even the date is debated: strong sources say 1951, others 1952. The story below follows the record, disagreements included.

Before the Pontoon Boat: Rafts, Ferries and Floating Platforms

The twin-float platform is far older than the outboard motor. Armies crossed rivers on pontoon bridges for millennia — Encyclopaedia Britannica records that Persian engineers floated Xerxes' army across the Hellespont in 480 BCE on a bridge of 676 ships in two rows. Twin-hulled working craft also predate Weeres: reporting by Pontoon & Deck Boat Magazine, drawing on period newspapers, found an 1897 river steamer running on two pontoons and a 1905 Michigan passenger boat whose hull was "two hollow cylinders, conical at each end and filled with air" — recognisably a pontoon boat, half a century early. Neither became a product. The idea lacked someone to build it, sell it and stand behind it.

Ambrose Weeres and the First Modern Pontoon Boat

Weeres farmed on the Horseshoe Chain of Lakes near Richmond, in Stearns County, Minnesota. As the company history preserved by Encyclopedia.com tells it, he welded 55-gallon steel drums end to end into two columns, laid a plywood deck across them, added a two-by-four railing, an outboard mount and a steering stick linked by lines to the engine, and tested the result on Horseshoe Lake with an acquaintance, Edwin Torborg.

Here the record forks, and honesty matters more than a tidy date. The Encyclopedia.com history, Boating Industry and Mercury Marine date the first boat to 1951. Pontoon & Deck Boat Magazine and Wikipedia date it to 1952 — the year Weeres founded his company. The likeliest reading is a 1951 prototype and a 1952 product launch, but no source states that outright, so treat any single-year claim with care. Two smaller disputes ride along: some dealer pages call the first floats aluminum, against every authoritative account, which says steel; and a few sources credit Torborg as the designer — a claim the Encyclopedia.com history itself flags as unclear, noting Weeres has been recognised repeatedly as sole inventor. What is undisputed is the next step: Weeres built a handful of boats, named the model The Empress — sources differ on whether that named the single first boat or the first small production run — and sold them through dealers. Nobody had done that before.

Weeres Industries and the Idea Spreads Across Lake Country

Weeres Industries was founded in 1952: four boats built the first year, orders for 40 more, and a Chicago boat show that brought another 100 orders. In 1955 the Winona Daily News named the Weeres Pontoon its Boat of the Year; in 1956 Weeres added a paddleboat of his own invention. The design brief never changed — maximum deck, maximum stability, minimum fuss. Minnesota made the credit official: in 1990 the legislature recognised Weeres as "Mr. Pontoon," and in 1991 he was among the first four inductees into the Minnesota Marine Hall of Fame — "Marina" Hall of Fame in several secondary sources, one more small fork in the record. Weeres had sold the company in 1954, but his template — twin tubes, flat deck, outboard power, dealer sales — spread across lake country and became an industry. Premier Marine acquired Weeres Industries in 2011, keeping the founding brand alive.

From Steel Barrels to Aluminum Tubes: The Materials Leap

Steel drums were what a farmer had, never the ideal float: they rusted, they were heavy, and their shape dictated the boat. From the late 1950s the industry shifted to purpose-built aluminum tubes. Godfrey Marine introduced the Sanpan in 1958, billed as the first all-aluminum pontoon boat — most histories place the debut at a Chicago boat show, though a few say a World's Fair, which Chicago did not host that year. Harris, founded in Fort Wayne, Indiana in 1957, followed around 1968, once welding equipment big enough for the tubes existed. Weeres was among the early aluminum adopters, though its own history gives no year — and none should be invented for it. Aluminum sat higher, ran faster on the same power, could be shaped into tapered, U- and V-form logs instead of inheriting a drum's silhouette, and does not rust out over a northern winter.

The Family-Boat Era: Pontoons Become America's Lake Boat

Harris drove the comfort revolution: a splash-guard nose cone in 1959 that became an industry standard, then upholstered furniture in the 1960s that turned a bare platform into a floating living room. The formula settled — fence rails, bench seating, a helm, a canopy — and the pontoon became the default lake boat for families. It still is: NMMA figures reported by Boating Industry put pontoons among America's three highest-volume boat categories, with an estimated 52,000–55,000 sold in 2024. On lakes like the one in our Lake of the Ozarks boating guide, they are the craft neighbours raft up and grandkids learn on.

The Tritoon and Performance Era: Lifting Strakes, Big Horsepower

Power crept up first: Harris fitted motor pods rated to 140 hp in the 1970s, enough to pull skiers. In the 1980s builders experimented with a third, centre tube for buoyancy and handling — Indiana's JC Manufacturing built its name on the design and holds the "TriToon" trademark, though some dealer roundups credit Manitou, whose documented contribution came later with its patented V-Toon hull. In the 2000s, performance packages borrowed lifting strakes from V-bottom speedboats; strakes have no single pontoon inventor, and any source naming one should be doubted. Then the horsepower race went wild: 300 hp outboards became normal on performance tritoons, and today's flagships carry twin engines totalling 900 hp at 70 mph or more. At the Lake of the Ozarks Shootout, Pontoon & Deck Boat Magazine records, a 46 mph run in 1995 was once unheard of; in 2010 two pontoons tied at 100 mph, and a triple-engine South Bay set the mark at 114 mph in 2013.

History of Pontoon Boats Myths Worth Retiring

"Weeres invented floating platforms." He did not — twin-float craft are ancient, and American examples predate him by decades. His invention was the product: a manufactured, dealer-sold family boat. "The first pontoons were aluminum." They were steel drums; aluminum came years later, and histories saying otherwise conflate prototype with production. "Pontoons are slow." True for fifty years; not now — see the 114 mph record above. "Old pontoons are used up." Aluminum logs routinely outlive furniture and engines, which is why the used market runs deep.

History of Pontoon Boats FAQs

Who invented the pontoon boat?

Ambrose Weeres of Richmond, Minnesota is recognised as the inventor of the modern pontoon boat — not because twin-float craft were new, but because he first manufactured and sold one through dealers. He tested the prototype with Edwin Torborg, whom a few sources credit as designer; that point is genuinely unresolved.

When was the first pontoon boat built?

Sources split between 1951 and 1952. The Encyclopedia.com company history, Boating Industry and Mercury Marine say 1951; Pontoon & Deck Boat Magazine and Wikipedia say 1952, the year Weeres Industries was founded. The honest answer is 1951–52: a prototype first, a company immediately after.

What were the first pontoon boats made of?

Steel. Weeres welded 55-gallon steel drums end to end under a plywood deck. Aluminum took over from the late 1950s — Godfrey's 1958 Sanpan was the first all-aluminum pontoon — because it is lighter, shapes better and does not rust.

What is the difference between a pontoon and a tritoon?

A tritoon adds a third, centre tube. The extra buoyancy carries bigger engines and more people, improves handling at speed and, with lifting strakes and performance packages, makes a genuine watersports boat.

Bottom line: the history of pontoon boats is a farmer's workaround that out-designed its critics for seventy years. Whatever era fits your lake, you will find it among the pontoon boats at BoatDealsDirect.com.
