US Patent 7236427 Vessel hull transducer modular mounting system

A vessel hull transducer modular mounting system enables transducers to be replaced and upgraded without necessitating the further modification of the hull and thus not necessitating the dry-docking of the vessel. A further feature includes the ability to reduce and dampen acoustic shock impact on the transducer. Another feature includes the ability to extend and retract the transducer which can operate in bottom scan, forward looking, side scan, searchlight, and sweep modes.
