[READ THIS FIRST!!] IMPORTANT NOTICE ON TIDE MEASUREMENTS (In nav-aided mode, tide accuracy depends heavily on gyro accuracy.) SETTING SHIP’S HEADING The CI-35/35H has the nav-aided mode to measure absolute tides even in deep waters where ground tracking is unattainable. To achieve reliable measurements, however, you must supply accurate heading (gyro) information and ship’s position (or speed/course) data to the CI-35/35H.
CALIBRATING COURSE OFFSET (Automatic) A. When ground-tracking is attainable: 1. Make sure the navaid (GPS) is working correctly and accurately. 2. On CI-35/35H, select ground tracking mode. (Press the TRACKING MODE key to see the “GT” mode indication on the display.) 3. In Menu 4, set ‘CRS CAL MODE’ to “GT”. 4. Run your boat at a speed about 10 kts, keeping the same direction. To minimize the effect of gyro speed error, it is desirable to run along parallels (i.e., eastward or westward). 5.
WHY IS GYRO DATA IMPORTANT IN NAV-AIDED MODE? If you consider the difference of tide vector calculations is ground-tracking mode and in nav-aided mode, you will realize how important the gyro (heading) information is. Tide Calculation in Ground-Tracking Mode In ground-tracking mode, the CI-35/35H derives tide information from the following data.
Tide Calculation in Nav-Aided Mode In nav-aided mode, the CI-35/35H derives tide information from the following data. (1) Ship’s speed/course sensed by the external navigator (GPS) (nav speed = pseudo ground speed) (2) Ship’s speed/course based on target layer (water speed) (3) Bearing of ship’s bow (Heading by gyro) Here, nav speed (1) is the ship’s speed vector sensed by the external navigator, and the moving direction is expressed with respect to true north.
CHAPTER 1. GENERAL 1. FEATURES ¡ The functions of CI-35 and CI-35H are same. CI-35H is type approved by MOT (Ministory of Transportation). ¡ Even in deep waters where ground (bottom) reference is not available acoustically, the CI-35/ 35H can provide absolute movements of measuring layers by receiving position (or speed) data from GPS navigator and heading data from gyro compass. It may be used on deep sea fishing boats or on ocean research vessels.
2. PRINCIPLE OF MEASUREMENT When a moving vessel emits an acoustical pulse into the water at an angle, a portion of emitted energy is reflected from the seabed and other microscopic objects in the sound path, such as plankton or air bubbles. The frequency of the received signal is shifted from the transmitted frequency in proportion to relative velocity between the vessel and underwater reflecting objects. This is called Doppler Effect.
Tide Tide is movement of watermass at a particular depth. To know absolute tide (speed on ground), the following two data are required: 1 Ship’s speed and course based on ground 2 Ship’s speed and course based on measuring layer (A) Absolute tide is, then, given as a difference of these two speed vectors.
Tide Differential Tide differential is a relative movement of tides at different depths, layer (A) and layer (B). To calculate tide differential, the following two data are used: 1 Ship’s speed and course based on layer (A) 2 Ship’s speed and course based on layer (B) Tide differential between two layers is, then, given as a difference of these two speed vectors.
3. TIDE, NAV-TIDE & TIDE DIFFERENTIAL Tide (Absolute tide) Absolute tide can be measured in the ground tracking mode. 10 NM (1 hour trip) Start of trip End of trip (Moving at 10 kt on ground) Layer A q (Moving at 3 kt on ground) w :Base of measurement Fixed Assume that the ship and layer A are moving in the same direction, and ship’s speeds based on ground (Vg) and on layer A (Vwa) are measured as; Vg = 10 kt (Ship’s speed based on ground) Vwa = 7 kt (Ship’s speed based on layer A).
Tide Differential Tide differential is a relative movement of tides at different depths. It can be measured in the ground tracking, water tracking and nav-aided modes.
Cd = = = = = C1 - C2 (Vg - Vwa) - (Vg - Vwb) Vwb - Vwa 5-8 -3 (kt) Tide differential based on layer B Speed of layer A viewed from layer B In the water tracking mode, watermass just below the transducer (near-surface layer) is taken as the base of all measurements (virtual ground). Therefore, the ship and tide speeds in the water tracking mode are not absolute but relative to this near-surface layer.
Tide differential calculations in water tracking mode Tide speeds of layer A (C1) and layer B (C2) relative to near-surface layer (Vw) are calculated as follows: D1 = Vw - Vwa (Speed of layer A based on near-surface layer) D2 = Vw - Vwb (Speed of layer B based on near-surface layer) The tide differential (Dd) between layers A and layer B is; Dd = = = = = D2 - D1 (Vw - Vwb) - (Vw - Vwa) Vwa - Vwb 8-5 3 (kt) Tide differential based on layer A Speed of layer B viewed from layer A Dd = = = = = D1 - D2 (Vw -

Depending on the tracking mode in use, the meaning of speed/direction changes as follows ` In the ground tracking mode, speed/direction values represent movement of the layer relative to ground. [Ground-based tide = Absolute tide] ` In the water tracking mode, speed/direction values represent movement of the layer relative to near-surface water.

(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.
TIDE VECTOR/COURSE PLOT SECTION TIDE HISTORY Display The CI-35/35H can hold last 24 tide samples collected at a time interval of 15 sec, 1 min, 5 min, 10 min, 30 min or 1 hour. 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.
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).

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.

CHAPTER 5. TROUBLESHOOTING 1. SELF-CHECK The CI-35/35H has a self-test facility for general diagnosis of its major circuits. If an unusual symptom is encountered during operation of the equipment, perform the self-check. If the self check reveals equipment fault, shown by the error code, report the results to the service technician when calling for service. (The user should not attempt further check inside the equipment.) WARNING Do not open the cover of the equipment.
