USING VMG FOR BETTER PERFORMANCE
VMG is an indication of how efficiently the yacht is sailing
upwind or downwind. Maximising your VMG ensures you are
following the fastest route upwind or downwind.
As a basic rule when heading directly for a mark the boat
speed should be maximised, when tacking or gybing to the
mark the VMG should be maximised.
USING THE LIGHTS KEY
The Network TACK Display unit has 3 levels of illumination
and off, controlled by the LIGHTS key. The level selected is
for the whole Network system.
• L0 OFF
• L3 High
• L2 Medium
• L1 Low
The LIGHTS key also changes the illumination level of the
key legends, it always remains illuminated so even in
complete darkness the key can be located.
