solid core or wood?

[Bob Favre]

I am getting ready to install an in hull transducer in my '86 222, but I don't know if it is a solid or cored hull...does body know? I thought I might put it in front of or beside the 5 gal. water jug up near the bow...any coments.

Once you have picked out a spot...

...for the transducer, here's how to check it. Put the 'ducer in a plastic bag with some water. Place it on the deck where you intend to mount it. Make sure to wet the deck just a little to ensure good sound transmission. If you get a reliable depth (you can cross check by holding the 'ducer in the water over the side). If the hull is solid in that spot, you'll get a good reading. If not, you won't. On my O'day 22 I mounted the transducer inside the starboard quarter berth locker, all the way forward and inboard. I am planningf to move it aft because in rough seas even that location tends to come out of the water. Where you are proposing will do liikewise, I think, you may want to go aft a little. You cannot mount the transducer over the keel, as that will block it. I'm going to try the same storage locker locaion, but at the aft end. I don't think the keel/ centerboard will be an issue there. Some info I have seen warns that the keel will block the transducer when you heel, I think that is nonsense, becasue the transducer and keel are fixed in relation to one another - when the boat heels, the keel heels, and the transducer heels too. One more thing - I mounted my transducer in silicne, not epoxy. I sure am glad I did that, now that I want to move it.

transducer mount

On my boat I drilled a hole in the center after spot where the portapotti goes. I used a 1 1/2 inch or 2 inch hole saw[ don't remember now]. This gave me acces to the hull somewhat forward ,but in the center of the boat. The hull I believe is solid, and this is where I epoxied the transducer. I covered the hole with a strip of teak. By doing it this way ,Iwas able to run the cable under the floorboards,and when the boat heels the affect is minimized.

solid fiberglass

perhaps my sad event can shed light on your quesation. Two years ago, while hauling my 222 out for the winter, I accidently punctured the hull (forward of the sink, below the water line). The repair was easy but I got to see how the hull was built. It's about 1/4" solid fiberglass/epoxy composite. I saw no core material at all.Good luck Ed
