The inverted transducer flats are designed primarily for a bronze style torpedo-shaped
transducer. An example of a torpedo shaped unit would be an Airmar Tri-Transducer. This
transducer is approximately ¾” thick. This thickness allows the transducer face to protrude below
the bottom of the hull. An additional ½” spacer may be installed between the hull bottom and the
transducer for optimum results. The transducer should be installed as far forward on the flat as
possible, and parallel with the keel.

Do not use the hardtop for storing heavy or large items such as a raft. The frame for the top is
designed for continual use with antennas, radar, and outriggers. The additional weight caused by
larger items such as a raft may cause damage to the frame structure.

The dockside power feature allows the use of AC equipment on board the boat. This
equipment includes any permanently installed appliances such as a battery charger or water
heater, or it may be a household item plugged into a receptacle. The dockside power is utilized by
connecting the heavy-duty cable supplied with the boat to an appropriate external power source.
This cable provides power to the boat’s AC inlet that is wired to the AC panel. The AC panel
allows for distribution to the various appliances and outlets. See the
for more information on component location and wiring specifics.
Connecting The Dockside Power
1. Verify that the external power source is a 3 wire grounded system with amperage and
voltage ratings compatible with the boat’s AC system ratings.
2. Be sure there is sufficient cable length to allow for normal movement between the boat and
the dock.
3. Turn all AC panel switches (including the main) to the “off” position. Turn the circuit
breaker under the starboard gunwale to off. Turn the circuit breaker at the dock outlet to off.
C A U T I O N
All seacocks should be in the “closed” position if not in use or if the boat is unattended to prevent
the taking on of water if a plumbing component fails.
N O T I C E
A flush mount style transducer will not work with the inverted flat.
C A U T I O N
Always disconnect the dockside power cable if leaving the boat unattended for an extended period
of time.
