best suited for sailboat operation as open array systems are more difficult to
protect from ropes and sails.
For sailboat installations, Raymarine offers a universal mast mount kit for each
radome scanner type. This optional mount is used to fit a radome scanner to a flat
surface on a mast with a minimum diameter of 60 mm (2½ in). When using the
mast mount kit, appropriate hardware should be used for the style and structure of
the mast aboard the vessel. Typically, the scanner will be mounted near the first set
of mast spreaders. If there is any doubt concerning the appropriate type of
hardware, consult your boat dealer or representative for their recommendations.
Depending on the type of sailboat, a radar scanner guard should be installed if the
sails could touch the scanner or platform. Without a proper radar guard the
mounting platform and the radar scanner could be severely damaged.
Mounting surface: power boats
On many small vessels the scanner unit can be installed on a mast platform, an
arch, or a bridge structure, but take care to follow the scanner site guidelines,
particularly regarding height. If necessary, construct a radar mounting platform to
obtain a sufficiently high mounting position. Make sure that the platform surface is
flat and the scanner unit drain hole (radome scanners) is not obstructed. Ensure the
platform is strong enough to support the maximum shock loads likely to occur.
Setting the radiation plane
The scanner unit should be mounted so that the array rotates parallel to the
waterline. The radar beam is approximately 25° wide in the vertical direction,
providing good target detection during the vessel’s pitching and rolling.
.
Planing hull vessels, and some displacement hull vessels, adopt a higher bow angle
when the vessel is at its cruising speed. In many cases this substantially alters and
raises the radar’s main radiation plane, and can cause poor detection of nearby
targets. It may be helpful to lower the radar beam back towards the parallel, by
shimming the rear of the radar, so that the beam points slightly downwards with
respect to the waterline when the vessel is at rest
