Watercraft device with hydrofoil and electric propeller system

A modular, weight-shift controlled watercraft device, comprising:

• a modular board removably attached to a power system;
• the power system including a modular power supply system, and a modular propulsion system;
• the power supply system including a first battery;
• the propulsion system including a modular strut, a modular propulsion pod, and a modular hydrofoil;
• wherein the strut includes a first end and a second end, and includes a strut body disposed between the first end and second end;
• wherein the board is removably attached to the first end of the strut;
• wherein the hydrofoil is removably attached to the strut body at a first location;
• wherein the propulsion pod is removably attached to the strut body at a second location interposed between the first end of the strut and the first location;
• wherein the power supply system includes a first tray housing the first battery;
• wherein the first tray is removably attachable directly to the first end of the strut;
• wherein a first portion of the strut body is interposed between the first end of the strut and the propulsion pod;
• and
• wherein a second portion of the strut body is interposed between the propulsion pod and the hydrofoil.
