The wave park further includes at least one foil coupled to move along the track, the at least one foil being at least partially submerged in the body of water. The at least one foil has a curvilinear cross-sectional geometry that includes a leading surface that is concave about a vertical axis to provide drag to generate a primary wave laterally in water of the body of water that contacts the leading surface of the foil, and a trailing surface that narrows from a maximum width of the foil adjacent the leading surface to a point at an end of the foil, the trailing surface to decrease the drag of the foil and to minimize oscillatory waves that trail the primary wave. ## Claims ### Claim 1 A wave park comprising: a pool for containing a body of water; a track positioned adjacent a side of the pool; and a foil coupled to the track, the foil positioned to at least partially extend into the pool, the foil having a curvilinear cross-sectional geometry that includes a leading surface that is concave about a vertical axis to provide drag to generate a primary wave laterally in the body of water that contacts the leading surface of the foil, and a trailing surface that narrows from a maximum width of the foil to a point at an end of the foil, the trailing surface to decrease the drag of the foil and to minimize oscillatory waves that trail the primary wave. ### Claim 2 (depends on 1) The wave park in accordance with claim 1, wherein the pool further comprises a deep region, and wherein the track is arranged proximate the deep region. ### Claim 3 (depends on 2) The wave park in accordance with claim 2, wherein the pool further comprises a bottom having a contour that slopes upward from the deep region toward a sill. ### Claim 4 (depends on 3) The wave park in accordance with claim 3, wherein the sill is formed by an elongated reef that is formed on the bottom of the pool. ### Claim 5 (depends on 1) The wave park in accordance with claim 1, further comprising a vehicle coupled with the foil and positioned on the track, the vehicle configured for moving the foil along the track. ### Claim 6 (depends on 1) The wave park in accordance with claim 1, wherein the track is linear. ### Claim 7 (depends on 1) The wave park in accordance with claim 1, wherein the track is curved. ### Claim 8 A wave park comprising: a pool for containing a body of water; a track positioned adjacent a side of the pool; and two or more foils coupled to the track, each of the two or more foils positioned to at least partially extend into the pool, each foil having a curvilinear cross-sectional geometry that includes a leading surface that is concave about a vertical axis to provide drag to generate a primary wave laterally in the body of water that contacts the leading surface of the foil, and a trailing surface that narrows from a maximum width of the foil to a point at an end of the foil, the trailing surface to decrease the drag of the foil. ### Claim 9 (depends on 8) The wave park in accordance with claim 8, wherein the pool further comprises a deep region, and wherein the track is arranged proximate the deep region. ### Claim 10 (depends on 9) The wave park in accordance with claim 9, wherein the pool further comprises a bottom having a contour that slopes upward from the deep region toward at least one sill. ### Claim 11 (depends on 10) The wave park in accordance with claim 10, wherein the sill is formed by an elongated reef that is formed on the bottom of the pool. ### Claim 12 (depends on 8) The wave park in accordance with claim 8, further comprising at least one vehicle coupled with at least one foil of the two or more foils and positioned on the track, the at least one vehicle configured for moving the at least one foil along the track. ### Claim 13 (depends on 8) The wave park in accordance with claim 8, wherein the track is linear. ### Claim 14 A wave park comprising: a pool for containing a body of water; a track positioned adjacent a side of the pool; a vehicle arranged on the track, the vehicle for moving along a length of the track; and at least two foils coupled with the vehicle on opposite sides of the track to be moved by the vehicle along the length of the track, each of the at least two foils positioned to at least partially extend into the pool, each of the at least two foils having a curvilinear cross-sectional geometry that includes a leading surface that is concave about a vertical axis to provide drag to generate a primary wave laterally in the body of water that contacts the leading surface of the foil, and a trailing surface that narrows from a maximum width of the foil adjacent the leading surface to a point at an end of the foil, the trailing surface to decrease the drag of the foil. ### Claim 15 (depends on 14) The wave park in accordance with claim 14, wherein the pool further comprises a deep region, and wherein the track is arranged proximate the deep region. ### Claim 16 (depends on 15) The wave park in accordance with claim 15, wherein the pool further comprises a bottom having a contour that slopes upward from the deep region toward at least one sill. ### Claim 17 (depends on 16) The wave park in accordance with claim 16, wherein each of the at least one sill is formed by an elongated reef that is formed on the bottom of the pool. ### Claim 18 (depends on 15) The wave park in accordance with claim 15, further comprising an elongated reef formed on a bottom of the pool proximate the deep region.
