Sailboats and RealVision 3D Transducers

[Chuck - Raymarine - Moderator]

Marinerjoe,

The scenario which you have identified is not one which has been tested by Raymarine's engineering team. As has been suggested within my prior post RealVision sonar technology is primarily intended for and tested for use in conjunction with fishing applications where the speeds, pitching, rolling, and yawing that a vessel engaged in such would encounter. The operational depth of RealVision sonar is also less than that of CHIRP (high CHIRP conical) and traditional 50kHz / 200KHz fishfinding sonar. It while it would be expected that the RealVision sonar technology may compensate for some degree of heel, Raymarine has not specified the limits of such. Accordingly, one may reasonably expect the technology to function well for a sailing vessel operating under power, but results may vary when operating under sail. That said, care must be taken with placement of the transducer to prevent reflection off of the keel. If simply seeking to determine the depth under a sailing vessel, it is generally recommended that an instrument transducer and instrument display be installed onboard.
