Tabs
Tabs data source can be selected with this setting. Tab data sources include; tabs, TVMs, and PCMs.
The following are the positions of the Tab source options.
1. PCM0 = starboard outer engine
2. PCM1 = port outer engine
3. PCM2 = center or starboard inner engine
4. PCM3 = port inner engine
5. TVM = pod drive
6. TAB = tab module
The Show option will determine if the tab data is displayed on‑screen, checked = yes, unchecked = no.
Tab calibration allows the operator to put the tabs in their uppermost and lowermost positions and record the percentages. This
is useful for determining the true 0° trim position—the point at which the tabs are parallel with the bottom of the vessel.
Correctly calibrated tabs will show an accurate position of the sliders on the screen.
To calibrate the tabs, trim the tab parallel to the hull, record the reading, this will be the tab's actual 0%. Trim the tab all the way
down, record the reading, this will be the tab's actual 100%. Select SAVE to keep the new calibrated tab data.
Tanks
There are many situations in which a tank may need calibration; odd shaped tanks, V‑bottomed tanks, stepped‑sided tanks,
and even a tank's aspect when the boat is in the water. Floats and senders can send inaccurate data to the operator, causing
problems with fuel and other volume display. The most accurate way to achieve tank calibration is to start with an empty tank
with a known capacity. Pump one quarter of the capacity and record the float or sender position. Repeat this procedure in one
quarter increments, recording the float or sensor position each time, until the tank is full.
Configure Tanks is covered during the Setup wizard process, but changes can be made at any time.
Tank Calibration
Tank calibration allows the operator to adjust the full through empty readings of a tank. When a tank is highlighted, press
ENTER to activate the calibration screen.
The default readings are in the second column, and can be selected by pressing the arrow buttons. In the following example;
we know that the fuel tank is full, but we are receiving a reading of 79 percent full. Select the RECORD button in the 100
percent row, VesselView will now consider a reading of 79 percent as full, and adjust the half and empty readings accordingly.
When the level of a tank is known to the operator, tank calibration can be used to correct the gauge reading to match the
known level at any time.
Speed
Speed source settings are covered during the Setup wizard process, but selection of GPS, pitot, and paddle wheel sources can
be changed with this menu. Strategy and GPS are the options. If the vessel is equipped with a GPS—connected to the CAN
network, choose this option. If the vessel is equipped with a pitot sensor and/or a paddle wheel, this option should be selected.
A speed strategy using pitot sensors and paddle wheels is covered later in this section.
Speed source has the option of choosing a GPS and the GPS source, the CAN P or the CAN H network. A strategy using a
pitot sensor and/or a paddle wheel can also be selected. Selecting the pitot or paddle wheel options brings up a selection of
sources.
Positions of the PCM options is shown in the following illustration.

The speed‑through‑water (STW) threshold is the approximate transition speed where the calculations from a paddle wheel
switch over to another source—GPS or pitot. The default speed can be changed by selecting the field and using the on‑screen
keypad to enter a new value.
