2.6 Choosing a Mounting Location

The selection of a suitable mounting location is important for the optimal performance of the
Maretron DST110. The mounting location and orientation of the DST110 should be:
1. Preferably on the starboard side of the hull —where propeller blades are moving downward
through the water.
2. Continuously Immersed In Water
3. Where Water Flowing across the Hull is Smooth with a Minimum of Bubbles and Turbulence
– especially at high speeds.
4. Where the Transducer Beam is Unobstructed by the Keel or Propeller Shaft(s)
5. Where there is a Minimum Deadrise Angle
6. Accessible from Inside the Vessel – with adequate headroom for the height of the housing,
tightening the nuts, and removing the insert. Allow a minimum of 280 mm (11").
Please follow the following guidelines for different hull types (see Figure 2):
1. Displacement Hull Powerboats – Locate amidships near the centerline.
2. Planing Hull Powerboats – Mount well aft, on or near the centerline, and well inboard of
the first set of lifting strakes to ensure that the DST110 is in contact with the water at
high speeds.
3. Outboard and I/O – Mount just forward of the engine(s).
4. Inboard – Mount well ahead of the propeller(s) and shaft(s).
5. Step-hull – Mount just ahead of the first step.
6. Boat capable of speeds above 25 knots (29 MPH) – Review the installation location and
operating results of similar boats before proceeding.
7. Fin Keel Sailboats – Mount on or as close as possible to the centerline and forward of the
fin keel 300 to 600 mm (1 to 2').
