Keel mounted shoes
Hydrophones can be keel mounted to avoid creating appendages
to the hull that could f oul the purse wire.
Keel mounted hydrophone shoes, top view.
(A) = Keel
(B) = Towards the bow
(S) = St arboard shoe with hydrophone
(P) = Port show with hydrophone
Should this solution be chosen, the following must be taken into
consideration:
• Hydrophones must have an unobstructed line-of-sight to the
sensors attached to the trawl.
• Hydrophones should be trained 20 degrees to either side of
the vessel’s centre line providing a 10 degree overlap and a
horizontal coverage area of 90 degrees.
• Hydrophones should be mounted as deeply as possible on the
hull, but not so deep that they may be damaged when
docking the vessel.
• For combined purse seine and trawl applications a seine
hydrophone may be m ounted in the starboard (or port)
blister/shoe along with the tr awl hydrophone.
