fly. If you can build a model airplane, you can create a hydrofoil boat.
With these principles, the builder can save $20 by not buying Ray

Hydrofoil Trimaran Sailboat (one of a kind) (HD) 2012
Glen Roberts selfmade Hydrofoil trimaran, 15 year project, test run 2012
Description, Epoxy glass, plascore skin construction. Dimension 26ftx31ft
with 3 T foils 9ft tall, with trailing flaps controlled by 3 foot pedals,
powered with a 30hp longshaft suzuki 2 stroke.
Next stage mast, rigging, sails and tramp.
The goal is to sail level and 5ft clear of surface with a smooth fast ride.
I've trailered the boat from home, about 30 min drive to the boat ramp, and
i can't help but wonder what a fantastic marketing tool

MONSTER TRUCK US military Ultra Heavy Lift Amphibious Connector
New concept for the US Marine Corps A potential replacement for the
Marines' 20-year-old air cushioned ship-to-shore craft has foam runners and
a massive payload.
Officials with the Marine Corps Warfighting Lab, in conjunction with the
Office of Naval Research, conducted a technical assessment earlier this
month with a half-scale version of the Ultra Heavy-Lift Amphibious
Connector, a high-tech craft being developed as an option to replace the
Landing Craft Air Cushioned as a vehicle to bring troops, vehicles and gear
ashore. The UHAC has also been discussed as a replacement for the Landing
Craft Utility, another Navy ship-to-shore connector, but Warfighting Lab
officials said they were especially interested in how the UHAC stacked up
against the LCAC.
The Navy's LCACs traditionally deploy with and operate from amphibious well
deck ships and often transport Marines to and from shore as part of
training or Marine Expeditionary Unit deployments.
Unlike the LCAC, which acts as a hovercraft with an inflatable skirt, the
UHAC has air-filled tracks made out of foam that can propel it through the
water and on land. The footprint of the UHAC is significantly larger: 2,500
square feet of deck area to the LCAC's 1,800. But this means the UHAC can
handle a much larger payload. While the LCAC can carry 65 tons of gear, the
UHAC can handle 150 tons, or 190 with an overload payload.
Capt. James Pineiro, Ground Combat Element branch head for the Warfighting
Lab's Science and Technology Division, said the UHAC would be able to carry
three main battle tanks ashore, at some 60 tons apiece.
Another advantage to the UHAC, Pineiro said, is its range: 200 nautical
miles to the LCAC's 86. And unlike the LCAC, when the UHAC arrives onshore,
it can keep on going, thanks to low pressure captive air cells in the
tracks. At about a pound per square inch, the UHAC can cross mud flats and
tidal marsh areas. And the tracks can crawl over a sea wall of up to 10
feet, he said — all important features during a beach assault.
"You could look at the amphibious invasion of Inchon, during the Korean
War," Pineiro said. "there were significant mud flats there, and a 26-foot
tide difference. At low tide it went a couple of miles out. That was a
problem during the invasion of Inchon."
Where the UHAC does come up short is in water speed. Because of the drag
created by the foam tracks, it can only travel at 20 knots, half the speed
of the LCAC.
But Pineiro said he anticipated that mission commanders would be able to
work around this drawback.
"When you get into planning ops, you kind of plan for your capability," he
Officials with the project said the concept for the UHAC originated in
2008, with a goal to design an amphibious vehicle with low PSI. The Office
of Naval Research accepted a concept design for the vehicle from the
company Navatek, Inc., and the project has been in development since then,
with the construction of a half-scale demonstrator and an at-sea
demonstration in 2012.
The half-scale model is still massive at 42 feet long, 26 feet wide and 17
feet high. It was in Honolulu in early March to complete a limited
technical assessment to demonstrate its capabilities. The test, Pineiro
said, involved launching the UHAC from a simulated ship's well deck with an
internally transported vehicle aboard. The UHAC brought the vehicle to the
shore and then returned to the ship, he said.
The assessment is preparation for a larger demonstration of the UHAC's
abilities at the Advanced Warfighting Experiment, also in Hawaii, that will
take place in conjunction with the international exercise Rim of the
Pacific 2014 this summer.
"We want to make sure the UHAC can perform," Pineiro said.
Future steps following this summer's experiment remain unclear as testing
continues. But according to the Marines Seabasing Required Capabilities
Annual Report for 2013, published in December, product managers with ONR
are working with Defense Department agencies to secure funding for
"Development of a full-scale technology demonstrator is a possibility," the
Amid budget cutbacks, one feature is sure to catch the eye of acquisition
officials: because of the technology involved in constructing and operating
a UHAC, ONR estimates per-unit production and maintenance costs would be
less than half that of an LCAC, officials with the project said.
The Navy began purchasing its 91 LCACs in the early 1980s at per-unit costs
ranging from $22 million to $32 million, or between $45 and $75 million
with inflation adjusted.
