I use the paddlewheel knotmeter to see trends in speed (faster or slower) as we adjust sails. It’s more sensitive than GPS for that.

The depth sensor is next to it and I had to replace both when one went bad. Had to cut larger holes through the hull to fit the newer style sensor sleeves, so I can share some stories. The "speed through the water" sensor is great for racing but when cruising, I simply use my cell phone, and Navionics and GPS speed. Bought a $15 clamp for the pedestal guard to hold the phone at the pedestal and love it. I keep the plug in the hull thru-hull 90% of the time, and only switch to the paddle wheel sensor, before racing. Found I don't miss the paddle wheel sensor readout. I monitor GPS instead.

I only had time to go to the boat this past weekend. Bill, the boat is a C&C 25 Here is an "annotated" drawing from Sailboat data that I will use for my questions: https://imgur.com/a/3Ar35Pb To me, there are three options (some easier than others) to cut the hull (2 inches round) and add the transducer: Red marker: At the moment, the original (I think?) depth sounder is located in the red marker *inside* the hull. Yellow marker: There is a small access port to the fibreglass on the yellow marker that *could* fit the depth/speed transducer. It feels very high on the hull and a bit fragile as the fitting would stick out of the access port and be a bit exposed (second picture of the link) Green marker: Last option, cut a square access *hatch* on the plastic liner wall (orange mark) that separates the "inside" of the boat from the fiberglass hull and then cut a hole on the green mark. Any mindhive thoughts? I am very nervous about making a hole in the wrong place :) Thanks!

There should be a section adjacent to the centerline where it is solid Glass before it goes up onto the balsa.

New electronics since 1982 on Spice. Im having a bit of a hard time finding where to place the transducer (airmar depth, speed, temp). Manual says ahead of the keel but access on the 25 Mk II seems limited. Anyone around here has any tips?
