Hull on a Catalina 30

Can anyone clarify whether the hull on a Catalina 30 is solid fiberglass or cored? Looking to install a transducer and the answer will determine whether a thru-hull or in-hull transducer can be used.

Don't know armandolio, but, if you can use an in hull transducer wouldn't it be better than drilling a hole in your boat? I just installed an in hull transducer in my 30 (AirMar 79(?) for my Garmin 740s and it works as expected.

Re: Hull on a Catalina 30

Call Catalina and ask for your hin number. You can use a in hull transducer in a cored hull. inner layer of core is removed and glass is remover and a layer of glass is used to seal the core edge. see instructions http://www.airmartechnology.com/uplo.../17-217-01.pdf

Re: Hull on a Catalina 30

I agree, I do not want to drill a hole in the hull. That is why I am trying to figure out if it is solid or not. It was also explained to me that I can test the transducer/hull by placing the transducer on a bag of water (at the location of installation) and check to see if it reads the depth.

BTW, it is a 1989 Catalina 30

Re: Hull on a Catalina 30

Catalina did not core hulls, only decks. Very few builders cored hulls.
