What does the brains trust think about locating a paddlewheel log relatively close to existing skin fittings - with regards to concerns about log accuracy, not hull integrity.?
Between 2 seacocks, roughly 30cm from each, in the path of flow between the 2 (ie directly downstream from the first, upstream from the second). It's not the speediest boat on the water. The transducer documentation states to avoid positioning it near existing skin fittings due to turbulent water flow and possible cavitation around them - but I wondered if this is more relevant to a higher speed boat.
Context: transducer is an Airmar DST810; boat is a Twister (long keel with cutaway forefoot), kept on a mooring which gets terrible fouling so I'm expecting to want/need to remove the transducer anytime the boat is left unused. The transducer is a bit of a pig to get in/out of the through hull (at least it is when trying it dry and not lubricated, with the through hull in my hand). That makes me want to put it somewhere relatively accessible, and where nothing is stowed (which would either need removing when the transducer is taken in/out, or would get wet). The most straightforward position for this is beneath the head, between its (forward) inlet and (aft) outlet - both Blakes seacocks. Further forward becomes less accessible, further aft likewise (and I'd prefer to have a transducer forward of the deepest part of the keel so I can edge into shallow water and know it is getting shallow before the boat actually goes aground).
