The PO of my 89 C27 sealed a depth transducer
to the inside of the hull
on the starboard side just aft of the keel
where the angle is as flat as could be. White epoxy
guessing maybe 4200. So his point was obviously to "sound" through the fiberglass hull
. The wire is cut and has been out of service
for a long time. This boat
does not have a thru hull
for a transducer
. I know a transducer will "sound" through a hull if it is surrounded by water
or sealed in with no air bubbles between the face and the bottom but I don't like the feel of doing it that way. I have tested this on an aluminum boat
. My questions are:
Does anyone know about this setup and what if any latency issues could cause a bad depth
to be returned possibly reporting a depth deeper than actual? And also might affect depth range? Might be negligible. Draft
is 4 ft and I don't like getting anywhere near that depth so if the true depth is 12 ft and my sonar says its 12.4ft It might not be an issue and i can always adjust the draft
setting to compensate.
I like not putting another hole in the bottom of the boat but is it a workable option to get the boat yard to make a thru hull
in a better place like forward of the fin keel
where it will be looking down with very little or no slant range? Making a proper setup that would be deep enough to avoid most aeriation.
I currently have my transducer mounted on a small pole jury rigged off the stern with no holes or screws in the boat and as normal my temporary setup has become permanent and I want to get this setup more in line with a proper setup.
Lastly, if this is 4200 or some tougher epoxy/sealant, what would be the best way to clean this off of my hull? I am very OCD about all spaces being clean and free of un-needed or abandoned stuff.
I can use my jury rig for now as I have a haul out
for bottom work
early next year and want to have a plan for all work
when that happens.
