Abstract
A watercraft includes a hull, an opening extending through the hull, the opening configured to receive a removable propulsion mechanism, and an insert removably insertable into the opening. The insert includes an inner cavity, an aperture configured to be at least partially submerged in a fluid when the watercraft is positioned on the fluid, the aperture being configured to provide fluid communication between the inner cavity of the insert and the fluid as the watercraft travels in a forward direction, and a surface shaped and dimensioned such that a first pressure within the inner cavity is greater than a second pressure at the aperture as the watercraft travels in the forward direction.
Claims28
A watercraft comprising:
- a hull;
- an opening extending through the hull, the opening configured to receive a removable propulsion mechanism;
- and
- an insert removably insertable into the opening, wherein the insert comprises:
- an inner cavity,
- an aperture located at a first location rearward of a second location, the aperture being configured to be at least partially submerged in a fluid when the watercraft is positioned on the fluid, and the aperture being configured to provide fluid communication between the inner cavity of the insert and the fluid as the watercraft travels in a forward direction, and
- a surface shaped and dimensioned such that a first pressure within the inner cavity is greater than a second pressure at the aperture as the watercraft travels in the forward direction and such that a first fluid pressure at the first location is lower than a second fluid pressure at the second location along the insert as the watercraft travels in the forward direction.
An insert configured to be received in an opening extending through a hull of a watercraft, the opening being configured to receive a removable pedal-driven propulsion system, the insert comprising:
- an inner cavity;
- an aperture located at a first location rearward of a second location, the aperture being configured to be at least partially submerged in a fluid when the watercraft is positioned on the fluid, and the aperture being configured to provide fluid communication between the inner cavity of the insert and the fluid as the watercraft travels in a forward direction;
- and
- a surface shaped and dimensioned such that a first pressure within the inner cavity is greater than a second pressure at the aperture as the watercraft travels in the forward direction and such that a first fluid pressure at the first location is lower than a second fluid pressure at the second location along the insert as the watercraft travels in the forward direction.
A watercraft comprising:
- a hull;
- an opening extending through the hull, the opening configured to receive a removable propulsion mechanism;
- and
- an insert removably insertable into the opening, wherein the insert comprises:
- an inner cavity,
- an aperture configured to be at least partially submerged in a fluid when the watercraft is positioned on the fluid, the aperture being configured to provide fluid communication between the inner cavity of the insert and the fluid as the watercraft travels in a forward direction, and
- a surface shaped and dimensioned such that a first pressure within the inner cavity is greater than a second pressure at the aperture as the watercraft travels in the forward direction and when a speed of the watercraft as the watercraft travels in the forward direction is between 2.5 and 20 meters per second.
