A hydrofoil is essentially composed of 6 elements. We are talking here about the mast base, the mast, the fuselage, the front wing, the rear wing and the fin. The mast base is the part that will be attached to the board and will be the junction between the board and the mast. Sometimes it is an integral part of the mast. The mast is the long, flat, vertical part that connects the board to the fuselage. The fuselage is the elongated part, positioned horizontally and in line with the board. its function is to connect the 2 wings together and to the mast. The front wing and the rear wing are obviously the parts that look like the wings of an airplane, which are positioned, in front of the mast for the front wing and behind for the rear wing, perpendicular to the axis of the board . The fin is a part, which is not present on all models and which is installed at the rear of the fuselage, a bit like a shark fin. Finally, there are often several hardware elements that connect all these parts together.
