Intake
A water intake device is disclosed for mounting on a boat hull so that at least a peripheral portion water-side face thereof is substantially flush with an exterior surface of the boat hull. The water intake device includes a plate or screen having the water-side face and having a plurality of througbores for water uptake. The throughbores are obliquely angled with respect to the water-side face to promote water intake, and preferably are angled at approximately 20 degrees.
1 . An intake device for a boat, the intake device comprising:
a body portion securable with a hull of the boat;
an intake plate having a water-side surface and an internal-side surface, and having a plurality of throughbores extending between the water-side and internal-side surfaces, the throughbores permitting passage of water therethrough and sized to impede ingress of undesirable matter therethrough, the throughbores being obliquely angled with respect to the water-side surface of the plate, the water-side surface of the plate generally following the contour of the hull.
2 . The intake device of claim 1 wherein the throughbores are obliquely angled between approximately 10 and 30 degrees from the water-side surface of the plate.
3 . The intake device of claim 2 wherein the throughbores are obliquely angled at approximately 20 degrees from the water-side surface of the plate.
4 . The intake device of claim 1 further including an abutment portion defining the amount of receipt of the intake within the hull, wherein a peripheral portion of the water-side surface of the plate is mounted substantially flush with an exterior surface of the hull.
5 . The intake device of claim 4 further including a mounting portion for mounting the intake within hulls of varying thickness.
6 . The intake device of claim 5 wherein the mounting portion includes a threadably adjustable nut having a face opposed to the abutment portion.
7 . The intake device of claim 4 wherein the abutment portion is formed on the body.
8 . The intake device of claim 1 wherein the body includes an interior passage in fluid communication with the plate throughbores for communicating water received therein to a raw water system, the interior passage being contoured to funnel the water to the raw water system.
9 . In combination with a boat hull having a thickness, an interior surface, and an exterior surface, a water intake device for delivering raw water to a portion of the boat, the intake device comprising:
a body portion securable with the hull of the boat;
an intake plate having a water-side surface and an internal-side surface, and having a plurality of throughbores extending between the water-side and internal-side surfaces, the throughbores permitting passage of water therethrough and sized to impede ingress of undesirable matter therethrough, the throughbores being obliquely angled with respect to the water-side surface of the plate,
wherein the water-side surface of the plate generally follows the contour of the hull, and the plate is secured with a peripherally portion thereof substantially flush with the exterior surface of the boat hull.
10 . (canceled)
11 . The combination of claim 9 wherein the throughbores are obliquely angled between approximately 10 and 30 degrees from the water-side surface of the plate.
12 . The combination of claim 11 wherein the throughbores are obliquely angled at approximately 20 degrees from the water-side surface of the plate.
13 . The combination of claim 9 wherein the intake device further includes an abutment portion defining the amount of receipt of the intake within the hull.
14 . The combination of claim 13 further including a mounting portion for mounting the intake within hulls of varying thickness.
15 . The combination of claim 14 wherein the mounting portion includes a threadably adjustable nut having a face opposed to the abutment portion.
16 . The combination of claim 13 wherein the abutment portion is formed on the body.
17 . The combination of claim 9 wherein the body includes an interior passage in fluid communication with the plate throughbores for communicating water received therein to a raw water system, the interior passage being contoured to funnel the water to the raw water system.
18 . A method of providing a boat with a supply of water for a water system, the method comprising the steps of:
providing a water intake device having an abutment portion for defining depth of receipt in the boat hull and having a water-side face for receiving water within the water intake device;
determining a size of the abutment portion;
providing an opening in the boat hull for receiving the water intake;
locating a shoulder within the opening at a position from an exterior surface of the boat hull, the position being based on the size of the abutment portion;
positioning the water intake device within the opening with the abutment portion substantially in contact with the shoulder and the water-side face having a peripheral portion substantially flush with the exterior surface of the boat hull.
19 . The method of claim 18 further including providing a plate having the water-side face.
20 . The method of claim 18 further including providing obliquely angled throughbores in the water-side face for permitting water passage therethrough.
21 . The method of claim 20 further including angling the throughbores with respect to the water-side face at an angle between approximately 10 and 30 degrees.
22 . The method of claim 20 further including angling the throughbores with respect to the water-side face at an angle of substantially 20 degrees.
