THE DELTA WING SUBMARINE 

               The Delta Wing Submarine (US
               Patent # 3,416,478) is a one-man
               craft designed from the ground up
               for divers. It is a simple project to
               build and easy to operate. Building
               costs are well within the reach of
               almost any diver.Performance is
               outstanding and should add many
               hours of pleasure to your diving. It
               was originally featured in the June
               1968 issue of Popular Mechanics
               Magazine and a large number of
               plans were sold. The sub is a semi-dry type (The
               upper part of the diver stays dry in an air pocket even
               while the craft is underwater).

               Propulsion is provided from two 12 VDC electric
               trolling motors at 36 pounds of thrust each. Electric
               power is supplied from three automobile batteries.
               The sub is set for slightly positive buoyancy and
               motors tilt up or down to change depth. Turns are
               made with the twin rudders. Running time is
               approximately four hours. Maximum depth is the
               same as with scuba gear. Air is supplied from a
               standard scuba tank, which lasts three times as long
               as when used with a swimming diver.



                         Specifications: Length 11'4", Width 4'5",
                         and Hieght 4'. Construction Materials:
                         exterior plywood with some fiberglass at
                         the rounded nose section. Bubble is easily
                         formed using a 1/4" acrylic plastic
                         sandwiched in a simple plywood mold,
                         heated at a plastic sign shop and blown
                         up.



               The sub is exremely stable with the weight down low
               and the air pocket up high. It is impossible to turn over.
               The maximum dive angle is about 15 degrees. Exit time
               from the craft in an emergency is under 5 seconds.
