The Higgins boat, formally known as the Landing Craft, Vehicle, Personnel (LCVP), played a pivotal role in amphibious operations during World War II. Designed for speed, versatility, and efficiency, the Higgins boat became an icon of the D-Day landings and other crucial military campaigns. This article provides an in-depth examination of the Higgins boat, covering its description, history, design, propulsion, construction materials, types, and enduring legacy.
The Higgins boat is a shallow-draft landing craft designed to transport troops, vehicles, and cargo from ship to shore. Its unique design allowed it to land directly on beaches, enabling rapid deployment in hostile environments. Measuring 36 feet (11 meters) in length and 10 feet 10 inches (3.3 meters) in beam, the boat featured a flat bottom and a ramped bow for quick unloading.
Higgins boats could carry up to 36 troops, 8,000 pounds (3,600 kg) of cargo, or a single vehicle such as a Jeep or small artillery piece. They were powered by inboard engines, achieving speeds of up to 12 knots (14 mph).

History
The Higgins boat was developed by Andrew Higgins, a New Orleans boatbuilder whose expertise in shallow-draft vessels revolutionized amphibious warfare. In the 1930s, Higgins designed small boats for fishing and oil exploration in the Louisiana bayous. His innovative designs caught the attention of the U.S. Navy and Marine Corps, which were seeking landing craft capable of beaching in shallow water.
By 1941, Higgins had refined the design of his Eureka boat into the LCVP. The addition of a bow ramp, inspired by Japanese landing craft observed in China, made the boat suitable for rapid deployment of troops and vehicles. During World War II, more than 23,000 Higgins boats were produced, becoming a vital tool in operations such as:
- D-Day (June 6, 1944): Over 1,000 Higgins boats were used to land Allied troops on the beaches of Normandy.
- Pacific Theater: Higgins boats played a key role in island-hopping campaigns, including the invasions of Guadalcanal, Iwo Jima, and Okinawa.
- Sicily and Italy: They supported amphibious assaults in the Mediterranean, including Operation Husky and the Anzio landings.
President Dwight D. Eisenhower famously credited Higgins with winning the war, stating, “Andrew Higgins is the man who won the war… if Higgins had not designed and built those landing craft, we never could have landed over an open beach.”
Design
The design of the Higgins boat prioritized simplicity, durability, and functionality. Key design elements included:
- Flat-Bottom Hull:
- The flat-bottomed hull allowed the boat to approach beaches and navigate shallow waters.
- This design, while practical for beaching, made the boat less stable in rough seas.
- Ramp Bow:
- The bow featured a retractable steel ramp, enabling troops and vehicles to disembark directly onto the shore. The ramp was 7.5 feet (2.3 meters) wide.
- Open Deck:
- The open cargo deck allowed for rapid loading and unloading of troops, vehicles, and supplies.
- Armament:
- The boat was equipped with two .30 caliber machine guns mounted aft for defensive purposes.
- Reinforced Construction:
- The hull was reinforced to withstand grounding on beaches and enemy fire.
Comparison of the Higgins boat with other landing craft:
| Feature | Higgins Boat (LCVP) | Landing Ship Tank (LST) | DUKW (Amphibious Truck) |
|---|---|---|---|
| Length | 36 feet | 328 feet | 31 feet |
| Beam | 10 feet 10 inches | 50 feet | 8 feet 3 inches |
| Capacity (Troops) | 36 | 200+ | 25 |
| Capacity (Cargo) | 8,000 pounds | 1,900 tons | 5,000 pounds |
| Primary Use | Troop/vehicle landing | Large-scale landings | Amphibious transport |
Propulsion
Higgins boats relied on powerful inboard engines to achieve sufficient speed and maneuverability. The primary propulsion system included:
- Engine:
- Higgins boats were powered by a 225-250 horsepower Gray Marine diesel engine. This reliable engine provided a balance of power and fuel efficiency.
- Propeller and Rudder:
- A single screw propeller and rudder allowed the boat to maneuver in tight spaces and navigate through surf.
- Speed and Range:
- The boat could reach speeds of 12 knots (14 mph) and had a range of 100 miles (160 km), sufficient for short amphibious operations.
Comparison of propulsion systems in landing craft:
| Craft | Engine Power | Speed | Range |
|---|---|---|---|
| Higgins Boat (LCVP) | 225-250 HP Diesel | 12 knots | 100 miles |
| LST | 1,700 HP Diesel | 10 knots | 4,000 miles |
| DUKW | 94 HP Gasoline | 6 knots (water) | 50 miles (water) |
Construction and Materials
The construction of the Higgins boat emphasized durability, simplicity, and mass production. Over 23,000 units were built during World War II, primarily by Higgins Industries in New Orleans.
- Wooden Hull:
- The hull was constructed from marine-grade plywood, making it lightweight yet durable.
- Steel Reinforcements:
- Steel was used for the bow ramp and key structural components, providing strength in high-impact areas.
- Mass Production:
- The simple design allowed for rapid assembly. Boats were produced at a rate of 700 per month at the height of production.
| Material | Characteristics | Applications |
|---|---|---|
| Plywood | Lightweight, easy to manufacture | Hull construction |
| Steel | Strong, durable | Bow ramp, reinforcements |
| Aluminum | Corrosion-resistant, lightweight | Engine fittings |
Types
Several variations of the Higgins boat were developed to meet specific operational needs:
1. Standard LCVP:
- The most common variant, designed for transporting troops, vehicles, and supplies.
2. Armored LCVP:
- Equipped with additional steel plating for increased protection in high-risk operations.
3. Logistic LCVP:
- Modified for cargo transport, featuring a reinforced deck and additional tie-down points.
