A passively stable personal hydrofoil watercraft that has a floation device, wherein a user can ride in a prone, kneeling, or standing position. The watercraft includes a strut having an upper end interconnected with the flotation device and lower end connected with a hydrofoil. The hydrofoil greatly reduces the power required to travel at higher speed. The watercraft also includes a propulsion system connected to the hydrofoil. Both longitudinal and directional control of the watercraft is via weight shift, eliminating the need of any movable surfaces. The floation device, strut, and hydrofoil may be permanently interconnected or may be detachable.

This invention relates to a method that can be used to scientifically fabricate pseudoscents of explosives, which, in their entirety, are comprised of non-energetic materials. It also discloses specific compositions of such pseudoscents, which can be used as energetically-inert-but-odoriferously-identical simulants for a range of explosives and are comprised of non-energetic components of the scent signature of an explosive and/or energetic scent components of the same headspace scent signature that have been rendered non-energetic. The scents achievable by the groups of formulations generated by this method encompass the different types of military and commercial explosives, and the components within the pseudoscents can be tuned to generate simulants representative of different qualities and quantities of such explosives. These explosive-scent simulants can be used to bolster existing explosive detecting dog (EDD) training programs, establish new training paradigms in canine, rodent, insect, and other creature explosive detection and training and, in some cases, increase the efficiencies of analytical instruments that rely on the phenomenon of vapor sampling to detect explosive materials.
