I have no experience with that particular sensor- but you will find the same comments from many manufacturers about any heading sensor and steel yachts. Essentially, they have no idea what the magnetic situation inside your boat is, and so make blanket statements stating that it won't work - covering their butts essentially. The fact is, most commercial
vessels are steel, and all have similar heading sensor devices. Some are mounted up high on aluminum
or wooden masts above the pilothouse to reduce magnetic interference
, and the same is sometimes done on sailboats (mount it on a mizzen mast
or stern arch); but go too high and vessel motions become a problem. Having a steel boat myself, I've read a lot on this now and in my unscientific review, roughly half the folks who face this ignore the advice and mount it below exactly the same as you would a wooden or fiberglass
boat - and have no issues. Some do have issues and are forced to move the sensor to a less problematic location... every situation is different.
Mount it temporarily where you find it most convenient (or where you would LIKE to put it permanently); then go for a test run. make sure you explore stability over all points on the compass
, with all potential electrical equipment
running below to ensure you've tested effectively. I bet that you'll be fine...
