Boat Speed
To understand the ltering of the boatspeed functions it is necessary to consider the order in which WTP3
calculates the various functions and where ltering is applied, this is shown in the owchart below:

Note: When shipped from the factory, Boat Speed is shown to two decimal places. However, due to the extra
responsiveness of the WTP3 system, especially when tacking, it may be desirable to change the displayed value to one
decimal place in the xout.d le.
