Presented is a beachable high speed marine vehicle with air cushioned
hull(s) capable of transporting heavy loads at very high speeds to
beachheads and then departing the beachhead under its own power. The
artificially pressurized air cushions allow the bow of the vehicle to be
raised to the water surface at all speeds including when stationary. The
design of the forward end of the air cushion recesses allows both high
speed breaking of water from the hull at that point and backing off of
the beachheads in spite of sand, rocks, and the like being inside the air
cushion forward end. An optional upward raising secondary bow is also
described. Monohull, multi-hulled such as catamaran, and outrigger hull
versions of the same conceptual invention are disclosed with all derived
from the same basic concepts regarding loading and unloading of cargo,
beaching abilities, air cushion performance, and other features.
