Hydrofoil watercraft with arcuate retractable strut system

A watercraft configured for hydrofoil operation, comprising:

• a flotation structure defining an outer envelope;
• at least one arcuate strut operatively coupled to the flotation structure and supporting a hydrofoil lift surface at a distal end thereof, the at least one arcuate strut being movable between a deployed configuration in which the hydrofoil lift surface extends below the flotation structure to generate hydrodynamic lift, and a stowed configuration;
• wherein the at least one arcuate strut transitions between the deployed and stowed configurations along an arcuate path about a radial axis positioned external to the flotation structure;
• wherein in the stowed configuration the at least one arcuate strut is contained substantially within the outer envelope of the flotation structure such that no portion of the at least one arcuate strut extends laterally beyond an outer lateral boundary of the flotation structure;
• wherein the watercraft in the stowed configuration has a transverse width permitting passage through a standard residential doorway.

A watercraft configured for hydrofoil operation, comprising:

• a flotation structure;
• a hydrofoil lift surface configured to generate hydrodynamic lift when submerged and moving through water;
• an arcuate strut coupled to the flotation structure and supporting the hydrofoil lift surface at a distal end thereof, the arcuate strut being movable between a deployed configuration in which the hydrofoil lift surface is positioned beneath the flotation structure to generate hydrodynamic lift, and a stowed configuration in which the arcuate strut is at least partially received within or against the flotation structure;
• and
• a radial axis positioned outside an outer boundary of the flotation structure, wherein the arcuate strut transitions between the deployed configuration and the stowed configuration along an arcuate path about the radial axis.
