What this video covers

Leo Goolden installs two tri-ducer transducers through the hull of Tally Ho, a wooden gaff cutter hauled out at a boatyard in Panama.0:11 The primary transducer had failed weeks earlier; removing it proved difficult because 3M 4200 sealant bonded the fairing block to the hull over a large surface area, ultimately requiring the fairing block to be destroyed before the bronze body could be twisted free.1:37 The replacement transducer connects directly to navigation software on a PC rather than the boat's NMEA 2000 network, so Leo cuts a second hole in the port side to install a NMEA 2000-compatible tri-ducer, giving depth readouts on cockpit displays and providing redundancy.9:05 Shaping the fairing block for the port transducer requires a compound bevel cut; with no adequate bandsaw in the yard, Leo cuts it by hand using cardboard guidelines, then uses the two halves as both the external fairing block and the internal backing block.11:01 Both transducers are wired and sealed but cannot be tested until the boat re-enters the water.17:12 The episode also covers the cove line being painted metallic gold over a yellow undercoat to mask future wear.0:11
