The Captain Fairy came to the boat recently and installed a depth finder... a Garmin P79 Transducer, which is fancy because it shoots a signal thru the hull instead of being mounted into the hull (meaning a hole thru your boat). I was toiling away working for the man so I missed the install, but the Captain Fairy said it was pretty easy. To mount the device, you caulk a ring around the base and then fill the base with antifreeze to keep air out. Otherwise the transducer would shoot thru air bubbles and give false reads. After that you put the transducer in and cap it off. Alas, depth finder installed.
After it was mounted to the hull, it needed to be connected to the electronics system in the cockpit. Captain Fairy used the old depth finder cable as a lead to pull the new cable thru the boat's guts. Then he fished it up the stanchions and connected it to the chart plotter. At long last we discovered the boat's slip is about 19 feet deep. Knowledge.
Now we'll know how much scope to put out and how deep our mooring spots are and if there are any fish down there and just how deep is the abyss we sail over out there. Dammit, why does knowledge always come with a tinge of fear? Cue the fear-busting mantra: Boats are made to float... If container ships can do it, we can.... What a glorious way to go....
Two people dumb enough to think anything is possible and smart enough to bumble their way into discoveries.
