      More than 20 years ago the through-hull transducer on Blue Days (35/209) was replaced by two in-hull transducers with a gravity changeover switch. These are Brookes and Gatehouse units and the new installation was carried out by a B&G engineer. The transducers are located under the floor in the forecabin and are mounted at the angle dictated by the hull V. The installation has always worked perfectly.

      Subject: [campernicholson] Depth Transducer - hull thickness

      I am trying to decide what to do wrt depth instrumentation for my CN 35.
      I am looking to upgrade or replace my Hercules Depthsounder, which would cost $200+ for each replacement transducer.

      Is anyone using an in-hull depth transducer (as opposed to thru-hull) ?

      I am trying to discover whether an Airmar P79 will work (probably with Raymarine ST 40 or 60)
      - Maximum hull thickness recommended for this transducer is

      Any information and or ideas would be appreciated.
