USGS Boat Equipment -
Model 4600
A
complete set of boat equipment consists of hardware used to attach
to a boat a sounding reel, which suspends a current meter or
sampling equipment off the boat. Included is equipment to attach
the boat to a tag line stretched across the river for the purpose
of maintaining the position of the boat along a particular cross
section of the river. The complete boat outfit consists of a
crosspiece that clamps or bolts to the side of the boat
perpendicular to the centerline; a retractable boom, which mounts
parallel to the centerline of the boat attaching to the crosspiece
and extending to the bow of the boat; and a nose unit which pivots
out over the bow of the boat. When the meter or sampling weight is
lifted, the assembly will be lifted out of the water where it can
be worked on.
The
width of the crosspiece is 69 inches (175 cm). The length of the
boat boom is 45 inches (114 cm) closed and extends to 75 inches
(190 cm). Special widths or other modifications to meet specific
boats can be custom built to meet your requirements. A reel mount
is provided for mounting A-55 or B-56 reels. The unit is shipped
in three pieces.
