13-5 Boat speed sensors

13-5-1 Selecting a boat speed sensor

The fuel calculations can use boat speeds from the GPS,

or from a paddlewheel sensor or pitot sensor if these

optional sensors are installed:

Paddlewheel and pitot sensors measure the speed •

through the water; GPS speed is speed over ground;

these sensors can give different values for Range,

Economy and the fuel consumption curves.

A pitot sensor is more accurate than a paddlewheel •

sensor at high speeds but is not accurate at low

speeds. A paddlewheel sensor is more accurate than

a pitot sensor at low speeds.

To select an optional speed sensor

> > Fuel > Speed source

To use a paddlewheel or pitot sensor > Water speed. To

use GPS speed > Ground speed

If you have both a paddlewheel sensor and a

pitot sensor

> Smart Craft > Speed type > Paddlewheel or

Pitot

Tip: You can select a different speed sensor during

a trip.
