"The landing craft, vehicle, personnel (LCVP) or Higgins boat was a landing craft used extensively in amphibious landings in World War II. The craft was designed by Andrew Higgins based on boats made for operating in swamps and marshes. More than 23,358 were built, by Higgins Industries and licensees.
Typically constructed from plywood, this shallow-draft, barge-like boat could ferry a roughly platoon-sized complement of 36 men to shore at 9 knots (17 km/h). Men generally entered the boat by climbing down a cargo net hung from the side of their troop transport; they exited by charging down the boat's lowered bow ramp. Taking the last letter of the LCVP designation, sailors often nicknamed the Higgins Boat the "Papa Boat" or "Peter Boat" to differentiate it from other landing craft such as the LCU and the LCM, with the LCM being called the "Mike Boat.""
