Underwater Craft

Watch Ryder

I've been gathering information about underwater craft for some time but wonder what the other scuba folk think.

You've basically got two types. Enclosed and Open.

For the open scubacraft it could be a new niche for diving in fast currents and previously unaccessible areas...

Underwater Craft and Vehicles

Below are the craft I've been looking at:

The Mantis Submersible

Mantis Machine!

The Mantis Submersible was made famous in the James Bond film 'For your eyes only'

Equipped with two manipulator arms it made an impression on audiences.
Deep Flight 1



The above craft is named 'Deep Flight I' and was built around 1995.

Over a decade later the world of underwater adventuring has moved further into developing and refining the art of underwater piloting of these craft. It is notable for being the fastest craft of it's class.

Specs:

Crew: One person, prone position
Life Support: 18 Hours
Flight Endurance: 1-4 Hours

Dimensions: 13 ft. long, 8 ft. wide, 3 ft. high
Weight: 2,860 pounds
Operational Depth: 3,300 fsw
Speed: Max: 12 knots (estimated). Cruise: 4-8 knots. Minimum: 2 knots

Construction: Glass/Epoxy composite (main structure)
Ascent Rate: 650 feet/minute
Descent Rate: 480 feet/minute
Attitude / Roll Range: Through 360 degrees



Deep Flight 2

Deep flight 2 is still in the development stage and is awaiting funding to move into the prototype stage.

Specs:

Crew: One person, two person, prone position
Configuration:Single person, fast survey craft
Two person, fast survey craft
Two person with work and hovering, maneuvering module (work package)

Life Support: 96 Hours
Flight Endurance: 8 Hours
Dimensions: 16 ft. long, 9 ft. wide, 4 ft. high
Weight: Est. 5000 lbs. single person config.
Operational Depth: 4,000/20,000/37,000 fsw
Speed: 6 knots
Construction: Ceramics (US Navy)
Ascent Rate: 700 feet/minute
Descent Rate: 400 feet/minute
Pitch: +/- 60 degrees
Roll: +/- 60 degrees



Deep Flight Challenger

A more up-to-date underwater craft. It's slow speed inhibits it, but it's tough construction and range make up for it.

Capable of 37,000 feet its record breaking attempt is currently in limbo as it's pilot died in a plane accident.

Specs:

Life support: 24 hours
Flight endurance: full ocean depth and back in 5 hours

Dimensions: Length 17 ft 8 inches, Width 12 ft 11 inches, Height 5 ft, 7 inches
Weight: 4730 lbs

Speed: Cruise – 2.2 knots; Max – 3 knots
Ascent/Descent Rate:350 feet/second at +/- 45 degrees
Operating Depth: 37,000 fsw
Crew: 1




Deep Flight Super Falcon

The latest underwater craft, still in the prototype stages, little is known about it so far.

Specs:

Unknown.



Scubacraft

Although it requires scuba equipment to breath independently the pilot of this craft can reach 50 mph at the surface then descend to a dive site or area. Uniquely for all underwater craft reviewed so far, it requires no boat to carry it and lower it below sea level. It can independently travel for miles prior to descending. Making it a versatile craft.
