[Mounting] Hydrophone Mount

[amcaleer271]

The current mount for the hydrophones is not functional and is hard to use

Requirements:

• Rigidly mount the hydrophones so they can take measurements under the surface of the water, they don't need to be deep, just fully submerged
• The hydrophones must be mounted in a location where they are not directly in the thrusters line of action.
• The hydrophones should be able to be removed from the mount without any tools
• The mount should be able to fold up or retract and be stowed securely during transit.
