The team at Nexus developed the Heel Switch System to solve the
speed discrepancy problems experienced when the speed and depth
transducers need to be installed away from the centre line. These
variances are common on multihulls, modern day short-handed yachts
and older classic keel style designs.
The Heel Switch System consists of two small heel boxes - one for
port and one for starboard - into which the two pairs of transducers are
wired. These boxes process the raw speed, water temperature and
depth data into the Nexus protocol, automatically selecting the correct
box depending on which tack / gybe the yacht is on.
The switching between the port and starboard boxes is done
automatically depending on the heel of the boat, which is provided by a
HPC Compass. If a compass isn’t ﬁtted, the switching will be made on
the apparent wind angle.
Included with this package:
The Heel Switch System includes
two heel switch boxes (one port and
one starboard) and one 0.4m interconnection
cable. Note: Additional transducers are not included.
