So Frank, if I have this right, you are saying that the consequences of your new deeper mooring and an accident to a through-the-hull fixture would be more drastic than when you were hanging onto a pontoon in shallow water.
And that you WILL be sailing around with a otiose column of water in the boat that could slosh out when well heeled in a rough sea (unless you top it with a screw cap).
Let's see, I have seven holes in my hull below the waterline and I would think the log transducer is the safest of the lot, being a solid plug that is firmly fitting the hole, with two O-ring seals and a substantial, watertight, screw seal with the cable epoxyed in. I worry far more about the cockpit drain configurations than that.
Admittedly, the green depths revealed through the open hole and flood of water into the boat as one removes the plug are dramatic but harmless enough unless some bolt of lightning or instant medical incapacitation should occur at that very moment to stop one from closing the gap - in which case the priorities would probably rapidly change anyway.
I really cannot see a problem with an unattended boat sinking from an accident with:
a)the transducer plug, it's too thick and solid even if the paddle wheel gets crunched, or
b) the sealed screw top of the skin fitting that replaces it when removed, it's too far from outside impact and influence.
Regards,
Brian.
