Wakeboat hull control systems and methods are provided to permit the accurate reproduction of a wake behind a wakeboat. The onboard wake control system receives data from a draft measuring system. Incorporation of the data from the draft measuring system permits accurate reproduction of a wake behind the wakeboat after a change in an onboard variable such as the number, weight or position of passengers, the weight or position of cargo and the position of trim tabs or amount/location of ballast.

A craft comprises at least one hull; at least one wing configured to generate upwards aero lift as air flows past the at least one wing to facilitate wing-borne flight of the craft; a front hydrofoil connected to the at least one hull via a front hydrofoil strut and configured to generate upward hydrofoil lift as water flows past the front hydrofoil to facilitate hydrofoil-borne movement of the craft through the water; a rear hydrofoil connected to the at least one hull via a rear hydrofoil strut and configured to generate upward hydrofoil lift as water flows past the rear hydrofoil to facilitate hydrofoil-borne movement of the craft through the water; and a control system. While the craft is hydrofoil-borne, the control system is configured to facilitate transition of the craft from hydrofoil-borne operation to wing-borne operation via a process comprising: while the upwards aero lift generated by the at least one wing is below a threshold lift, controlling one or both of the front hydrofoil and the rear hydrofoil to generate a downward hydrofoil lift that causes the front hydrofoil and the rear hydrofoil to remain at least partially submerged in the water; and after the upwards aero lift generated by the at least one wing has increased above the threshold lift, transitioning the craft from hydrofoil-borne operation to wing-borne operation at least in part by controlling one or both of the front hydrofoil and the rear hydrofoil to switch from (a) generating the downward hydrofoil lift to (b) generating an upward hydrofoil lift that pushes the craft up and out of the water.

A foil assembly for a hydrofoil, a hollow T-shaped connector for mounting in such a foil assembly, and a hydrofoil that includes such a foil assembly. The foil assembling comprises a mast having a first transverse longitudinal cavity, a foil, and a T-shaped connector having a first part that includes a first mechanism for fixing to the foil and a second part that includes a second mechanism for fixing to the mast. The T-shaped connector also has a second transverse longitudinal cavity that leads into the first cavity, such that the first transverse longitudinal cavity and the second transverse longitudinal cavity together form a chamber that allows for protection of elements which are useful for the operation of the hydrofoil.

An integrated passenger or goods transport system, comprising: a vessel (10) capable of maintaining itself at a fixed height with respect to the floating surface (100), in all conditions of speed and sea state. A system capable of supporting the vessel once it has rested thereon (31). A quick-release coupling system (50) of the pylon (14) and the submerged body (11), in which the propulsion system (20, 22 and 23), the drive system of the wings (12) and the rudder (21), the batteries (19) are contained. A system (70) for recovering and moving the submerged body (11) and the pylon (14) when they are released from the upper part of the vessel (16). This system (70), consisting of an arm having two movements, one in the vertical direction and one in the transverse direction, is also capable of sliding longitudinally on a trolley (71). Once the arm is engaged to the lower part of the vessel, the electrical and hydraulic connections are also restored: this makes it possible to charge the battery, download data for diagnostics and maintenance.

Safety strut assembly (9) for a hydrofoil craft (1) comprising a strut (12), which is attached to the hull (10) of the craft by means of a transverse oriented strut axle (40) for pivotal movement with respect to the hull, the assembly further comprising: a control rod (33) passing down through the strut (12); a linear actuator assembly (28); a hydrofoil (13) pivotally mounted to the bottom portion of the strut (12) about a transverse oriented foil axle (35); first linkage means (34) connecting the hydrofoil (13) to the control rod (33); wherein the first linkage means (34) comprises a first drive ring (48) mounted around the foil axle (35), wherein the first drive ring is provided with one first ring cam element (45), and wherein the foil axle (35) is provided with one foil axle cam element (46).

A craft comprises at least one hull, at least one wing configured to generate upwards acro lift as air flows past the at least one wing to facilitate wing-borne flight of the craft, at least one retractable hydrofoil configured to generate upwards hydrofoil lift during a first mode of operation as water flows past the at least one hydrofoil to facilitate hydrofoil-borne movement of the craft through the water, and a control system that comprises data storage having instruction code stored thereon that causes the control system to during a takeoff operation when the craft is accelerating through the water and is supported by the at least one hydrofoil, control the at least one hydrofoil to generate downwards hydrofoil lift that maintains the at least one hydrofoil submerged at a predetermined hydrofoil depth threshold below the water surface; and when the craft reaches a takeoff condition, cause the least one retractable hydrofoil to release the craft from the water to facilitate wing-borne flight of the craft.

While a craft is hydrofoil-borne, a control system is configured to facilitate transition of the craft from hydrofoil-borne operation to wing-borne operation via a process comprising: while upwards aero lift generated by at least one wing is below a threshold lift, controlling one or both of a front hydrofoil and a rear hydrofoil to generate a downward hydrofoil lift that causes the front hydrofoil and the rear hydrofoil to remain at least partially submerged in the water; and after the upwards aero lift generated by the at least one wing has increased above the threshold lift, transitioning the craft from hydrofoil-borne operation to wing-borne operation at least in part by controlling one or both of the front hydrofoil and the rear hydrofoil to switch from (a) generating the downward hydrofoil lift to (b) generating an upward hydrofoil lift that pushes the craft up and out of the water.
