8 . The hydrofoiling watercraft of claim 1 , wherein the hydrofoil wing comprises a cross-section having a concave lower surface and a downward-sloped trailing edge.
9 . A hydrofoiling watercraft comprising:
board having a top surface for supporting a user and a bottom surface;
a plurality of masts extending downwardly from the bottom surface of the board;
a plurality of fuselages having a forward portion extending toward a direction of travel for the watercraft and a rearward portion extending opposite the forward portion, wherein individual fuselages are rigidly mounted to an outboard end of a respective one of the plurality of masts;
a hydrofoil wing rigidly mounted to the plurality of fuselages at the forward portion of each respective one of the plurality of fuselages; and
a tail wing rigidly mounted to the plurality of fuselages at the rearward portion of each respective one of the plurality of fuselages,
wherein the hydrofoil wing comprises a cross-section having a concave lower surface and a downward-sloped trailing edge.
10 . The hydrofoiling watercraft of claim 9 , wherein the hydrofoil wing further comprises:
two side portions extending outwardly from outermost ones of the plurality of masts,
wherein the side portions sweep rearwardly away from the direction of travel for the watercraft.
11 . The hydrofoiling watercraft of claim 9 , wherein the hydrofoil wing further comprises:
two side portions extending outwardly from outermost ones of the plurality of masts,
wherein the side portions each angle downwardly away from the board.
12 . The hydrofoiling watercraft of claim 9 , wherein the board further comprises:
a flotation portion having a right side and a left side;
a right winglet extending outwardly from the right side of the flotation portion; and
a left winglet extending outwardly from the left side of the flotation portion;
wherein a first one of the plurality of masts extends downwardly from the right winglet and a second one of the plurality of masts extends downwardly from the left winglet.
13 . The hydrofoiling watercraft of claim 9 , wherein the hydrofoil wing comprises two side portions extending outwardly from outermost ones of the plurality of masts.
14 . A hydrofoiling watercraft comprising:
a board having a right side, a left side, a bottom surface, and a top surface for supporting a user;
a right mast extending downwardly from the right side of the board;
a left mast extending downwardly from the left side of the board;
a hydrofoil wing comprising:
a first wing portion extending substantially between the right mast and the left mast;
