Attachment mechanisms for electric hydrofoils and associated systems and methods

A hydrofoil system, comprising:

• a board comprising a first board surface, a second board surface opposite the first board surface, and a board connector assembly attached to the second board surface, the board connector assembly comprising:
• a base defining a recessed portion;
• and
• a first electrical connection component positioned in the recessed portion;
• and
• a hydrofoil assembly comprising a mast having a first end portion and a second end portion opposite the first end portion, a motor positioned along the mast, and a hydrofoil connector assembly at the first end portion, the hydrofoil connector assembly comprising:
• a connector collar including a second electrical connection component, the second electrical connection component comprising at least one phase wire connector, wherein:
• the at least one phase wire connector is electrically coupled to the motor,
• the recessed portion of the base is configured to receive the connector collar, and
• upon insertion of the connector collar into the recessed portion, the first electrical connection component electrically connects to the second electrical connection component.

A hydrofoil system, comprising:

• a board comprising a first board surface, a second board surface opposite the first board surface, and a leash connector at the first board surface;
• a hydrofoil assembly extending from the second board surface, the hydrofoil assembly comprising a mast having a first end portion and a second end portion opposite the first end portion, and a motor positioned along the mast between the first end portion and the second end portion;
• and
• a leash having a board end portion and a user end portion opposite the board end portion, the user end portion comprising a user attachment component and the board end portion releasably coupled to the leash connector and operably coupled to the motor via the leash connector,
• wherein:
• the board end portion of the leash is configured to decouple from the leash connector when a non-zero threshold force is applied to the board end portion, and
• upon decoupling of the board end portion from the leash connector, the motor is configured to terminate operation.

A method of operating a hydrofoil system, the method comprising:

• inserting a connector collar of a hydrofoil assembly into a receptacle formed in a bottom surface of a board, wherein the hydrofoil assembly comprises a mast having a first end portion and a second end portion opposite the first end portion, a motor positioned along the mast, and wherein the connector collar is positioned at the first end portion,
• upon inserting the connector collar into the receptacle, making an electrical connection between at least one board electrical connector positioned in the receptacle and at least one phase wire connector positioned in the connector collar;
• inserting at least one fastener through at least one collar connector hole formed in a flange surrounding the connector collar and at least one mounting plate hole formed in a mounting plate surrounding the receptacle;
• and
• passing energy from a battery positioned in the board through the at least one board electrical connector and the at least one phase wire connector to the motor.
