An external circuit is connected to a polarity detection terminal of a switching control IC. The hydrofoils create a counteracting force to the waves that would otherwise cause the vessel to roll and pitch. Each bit-slice may be programmed to perform a basic Boolean logic operation or may be programmed to contribute to higher-level functions that are further programmed by an ALU controller circuit. A mounting area is formed on the opposite side of the receiving area, and includes coaxially aligned bores for passage of a mounting bolt through a upper and lower clamp members. The method may optionally include sending a predetermined identifier to the dictation file to associate the image file with the dictation file.
