NW Explorations
HELE MAI OPERATING MANUAL
|
39
Operation of this system is described in its operating manual. It is turned on by the breaker in the DC power panel.
Because our waters are sometimes very deep, the depth sounders will not display or will stay on a high depth reading
when the water’s depth is beyond its capacity.
Remember when backing up, or crossing a “tide line”, that turbulent water from the tides or boat’s screws (or those of
another boat) can interrupt the sounding information received by the unit. Be careful!
Note that our Northwest waters are rocky and depths change rapidly. You should be especially careful to study your
charts, and then check them often whenever running in depths of 50 feet or less, so that you don’t hit a rock! Just as
our islands “pop up” to heights of 50, 100, or even thousands of feet in a very small horizontal distance, so do rocky
obstacles!
4H3: Electronics: Depth Sounder - Graphic
This depth sounder (shown by paragraph 4H2 above) works on either of two frequencies and serves as an accurate fish
finder as well. Display is on any of the Raymarine multipurpose displays.
For full operation instructions, see the unit’s manual.
4H4: Electronics: Depth Sounder - Interphase Forward-Looking
There are two displays for this depth sounder system, one at each helm. This unit
is intuitive in operation, and the more it is used, the more you will understand its
important role in safe operation of Hele Mai. It shows obstructions forward and to
the sides of the vessel. See its manual for operating and interpreting details.
4H5: Electronic Displays
The pilothouse has two displays that can show
the plotter, radar, sounders, cameras, fish
finder, etc. Each operates independently of the
other.
