A duck boat, commonly referring to the DUKW (an amphibious vehicle developed during World War II), can reach a maximum speed of 50 mph (80 km/h) on road and 6.4 mph (6 kn or 10 km/h) in water.
These speeds highlight the dual nature of these unique vehicles, designed for seamless transitions between land and water operations.
DUKW Speed Capabilities
The DUKW, a six-wheel-drive amphibious truck, was engineered to transport goods and troops over both land and water. Its design allowed it to serve crucial roles in military logistics, particularly during beach landings where conventional vehicles would be impractical.
Here's a breakdown of its maximum speeds:
| Operational Environment | Maximum Speed |
|---|---|
| On Road | 50 mph (80 km/h) |
| In Water | 6.4 mph (10 km/h or 6 knots) |
Performance on Land
On solid ground, the DUKW's robust engine and all-wheel drive system enable it to achieve speeds comparable to many standard trucks of its era. With a powerful drivetrain, it can navigate various terrains, from paved roads to rough off-road conditions, while carrying a significant payload. Its operational range on road extends up to 400 miles (640 km), showcasing its capability for extended land-based travel.
Performance in Water
When transitioning to water, the DUKW uses a propeller at the rear for propulsion and its front wheels as rudders for steering, although this steering is less precise than land steering. While its water speed is considerably lower than its land speed, it is sufficient for crossing rivers, lakes, and coastal waters, enabling it to deliver cargo or personnel directly from ship to shore without the need for docks or jetties. This amphibious capability was revolutionary for military operations and later adapted for civilian tourism.
Modern "Duck Boats"
Today, the term "duck boat" often refers to a variety of custom-built or modified amphibious tour buses used in cities worldwide for sightseeing tours. While these modern tourist vessels may share the amphibious concept, their exact speeds can vary depending on their specific design, engine, and hull shape. However, the original DUKW's performance provides the benchmark for these unique land-and-water vehicles.
