(Refer to page 4-2. ) ` Tide differential vectors can be switched on and off by MENU 1 - "TIDE DIF DISP" setting. (Refer to page 4-2. ) ` Each vector bar indicates "flowing to" own ship direction with the standard factory setting. It is possible to reverse the pointing direction to "flowing from.

The tide history presents variation of these tide information with a string of round marks. That is, distance from the graphic center to a mark represents tide speed at the sample time, and the direction from the center to a mark represents tide direction. The figure below can be interpreted that the tide has changed from SW to NE (opposite) direction. The tide history of layers activated in MENU 1 - "LAYER n" are displayed. (The figure below shows history of only one layer. ) ` To restore normal tide vector display, press the HISTORY key again. Tide history of layer 1 (last 24 samples) N NW NE Present tide vector for layer 1 W E SW Interval S SE You can select sampling time interval of tide history in MENU 1. (See page 4-2. ) Note: The CI-35/35H preserves the tide history data stored in the memory when the power is off. 3-11 TIDE VECTOR/COURSE PLOT SECTION COURSE PLOT Display The course plot display provides ship's track of last 20 minutes (200 points, one point sampled every 6 seconds). Event positions, stored by the ` Press the PLOT previous display. COURCE EVENT key, are also plotted with "+" marks. key to call course plot display, and press the same key again to restore N NW NE Present position W E Event marks Positions memorized by the EVENT key. SW SE S Ship's track (200 points max. ) ` To change display range (distance range) of course plot, press the `DIST RANGE' in the RANGE menu. (See page 4-10. ) RANGE key and set desired ` To clear event memory (marks), select `ERASE' in MENU 1 - "EVENT" and then press the EVENT key. Note: ` Capacity of ship's position memory (for course plotting) is limited to 200 points. When the position memory is fully occupied, the oldest position is erased as new one comes in. ` Sampling interval of ship's position is fixed to 6 seconds, and it can not be changed. 3-12 TIDE VECTOR/COURSE PLOT SECTION TIDE EFFECT Display The tide effect display is useful for estimating three-dimensional deformation of cast net by the effect of tides at different depths. Notice that display merely shows movements of layers; it does not show true net shape in the water. Assume that you put drifting marks (virtual buoys) on the net at each layer below the vessel at an interval of six seconds. Virtual buoys Layer 1 (YEL) Layer 2 (PPL) Layer 3 (L-BLU) As the marks move with the tides keeping the same speeds and directions, a series of marks makes a brief section shape of the net at the layer. Layer 1 Virtual buoys Layer 2 Layer 3 Interval (6 sec) 100 points max. ( = 10 minutes) In practice, a net does not sink immediately, because of various tensions and stresses placed on it. [. . . ] Variation of echo strength with depth is presented either in color sounder mode or in A-scope mode. (simultaneously for the three sounding beams) Tide differential vector: Echo level: Optional graphic display (display on/off switchable) Course track plot: Ship's course track display consisting of the last 200 sampling points is presented in ship-centered format. (Display switchable on/off) Tide vectors recorded at last 24 sampling points are presented on one screen. (24 hours max. ) Simulated movements of tide layers along the ship's track. [. . . ]
