keep the transducer perpendicular to the waterline. A fairing block which
can adjust for angles of up to 25° is available from Raymarine.
1. Measure the deadrise angle of the hull at the selected mounting
point.
2. Cut the block to a shape which fits the exact contour of the hull. The
cut-out portion can be mounted inside the hull to provide additional
support for the transducer once it is mounted.
3. Attach the fairing block to the hull as firmly as possible. This fairing
block must be able to resist the drag of the water against the hull, and
must also be completely waterproof.
