WWII
U.S. military
Assault boats in the U.S. military during World War II were typically the property of Combat Engineer Battalions, whose combat engineers also deployed and crewed them. The Americans deployed two types of assault boat: The "storm boat" was an 8-man (6+2 crew) high-speed assault boat with a 55 horsepower outboard motor, designed to breach at speed, thus allowing the soldiers on board to "storm the shore"; the M2 was a ten-man boat (8+2 crew) that was paddled.British
The British used two types of assault boat: a "storm boat" and a lower performance canvas boat, The Goatley boat.Overview of the differences between British and American Storm and Assault Boats

a. British Canvas Boats. (The 'Goatley boat') :(1) Easily portable (Could be carried open by four men). :(2) Easily maneuvered in the water when loaded. :(3) Easily damaged in transit by rough handling. :(4) Not easily repaired. b. U.S. Plywood Boat, M-2. :(1) Not so easily portable. :(2) Easily maneuvered in the water, loaded or empty. :(3) Not so easily damaged in transit (boats "nest"). :(4) More easily repaired. :(5) Served dual purpose (i.e. making infantry support rafts and expedient assault boat bridge). :(6) Much noisier in use with non-rubber shod personnel. c. Conclusions: :(1) The American pattern assault boat was decidedly more robust and had the great advantage of dual purpose. However, the British boat proved itself perfectly adequate for its primary task which did not require excellent durability.Storm Boats
a. British Storm Boat. :(1) Heavier to carry across the country. :(2) Would carry the heavier load (6-pounders or jeep though the latter a top-heavy load). :(3) Carried ten men, but with a lower speed. b. American Storm Boat. :(1) Carried by 6 men (plus 2 for motor). :(2) Would carry up to 1500 lbs with very little reduction in speed. :(3) Carried 7 men (above crew) at maximum speed. :(4) Was the faster boat; would beach at full speed. c. Conclusions: :(1) For assault crossing of personnel the U.S. boat carried fewer men but got them across the river and in action much faster. :(2) For cargo carrying, British boat carried a greater load but at a slower speed.See also
