Equipment mount for waterborne vessels

1. An apparatus for mounting equipment on a waterborne vessel, the apparatus comprising:

a base member;

an elongate spacer arm connected to the base member, the elongate spacer arm comprising:

a base member end configured to connect to the base member; and

a distal end opposite the base member end;

wherein the length of the spacer arm is at least sufficient for the distal end to reach a gunwale of the vessel when the base member is mounted inboard the vessel;

and

a selectively deployable elongate transducer arm pivotably coupled to the spacer arm, the elongate transducer arm comprising:

a proximal end configured to pivotably connect to the distal end of the spacer arm at a pivot point; and

a transducer end opposite the proximal end, the transducer end being configured to attach to a transducer;

wherein the transducer arm is configured to pivot between a deployed position and a stored position; and

wherein the length of the transducer arm is at least sufficient for the transducer end to reach the water surface when the transducer arm is in the deployed position;

wherein the spacer arm is substantially parallel to or collinear with the transducer arm when the transducer arm is in the stored position, allowing the apparatus to be folded for compact storage; and

wherein the spacer arm is movable with respect to the base member such that, when the spacer arm is in a stored position, the distal end and the pivot point are inboard the vessel and, when the spacer arm is in a deployed position, the distal end and the pivot point are outboard the vessel while the base member remains mounted inboard the vessel.

2. The apparatus of claim 1 , wherein at least one of the spacer arm and the transducer arm is configured to telescope so as to have an adjustable length.

3. The apparatus of claim 1 , further comprising a mount member configured to sit on a deck of the vessel and secure the base member to the vessel.

4. The apparatus of claim 1 , wherein the base member is configured to sit on a deck of the vessel, and wherein the base member comprises a fastener to secure the base member to the vessel.

5. The apparatus of claim 1 , wherein the base member comprises a substantially planar surface sized to support the display of a fish finder.

6. The apparatus of claim 5 , wherein the spacer arm is pivotally connected to the base member such that the spacer arm can be rotated within a plane parallel to the substantially planar surface of the base member.

7. The apparatus of claim 6 , further comprising a spacer arm locking pin configured to anchor the position of the spacer arm at a spacer arm angle with respect to the base member, wherein the base member comprises a plurality of locking pin receptacles such that the spacer arm can be anchored in a plurality of different positions.

8. The apparatus of claim 6 , further comprising one or more post members extending from the base member, wherein the one or more post members restrict an angle through which the spacer arm can be rotated.

9. The apparatus of claim 8 , wherein the one or more post members comprise two post members that allow the spacer arm to be rotated through an angle of approximately 90°.

10. A method of using an equipment mount to deploy a transducer from a waterborne vessel, the method comprising:

securing a base to an inboard deck of the waterborne vessel, wherein the base is connected to a spacer arm and to a transducer arm, wherein the transducer arm is pivotably attached to the spacer arm at a pivot point;

providing an instrument having a display unit and a transducer, wherein the display unit is disposed on the base;

fastening the transducer to an end of the transducer arm opposite a portion of the transducer arm attached to the spacer arm;

moving the spacer arm with respect to the base member from a stored position, in which a distal end of the spacer arm and the pivot point are inboard the vessel, to a deployed position, in which the distal end and the pivot point are outboard the vessel while the base remains mounted inboard the vessel; and

swinging the transducer arm about the pivot point to rotate the transducer arm from a stored position to a deployed position;

wherein the transducer arm is parallel to or collinear with the spacer arm when the transducer arm is in the stored position; and

wherein the transducer is positioned underwater when the transducer arm is in the deployed position.

11. The method of claim 10 , further comprising selecting a measurement angle for the transducer by adjusting a deployment angle of the transducer arm.

12. The method of claim 10 , further comprising selecting a measurement angle for the transducer by adjusting a spacer arm angle of the spacer arm.

13. The method of claim 10 , further comprising rotating the spacer arm into a longitudinal position with respect to the waterborne vessel and securing the spacer arm in the longitudinal position.
