So Gary, long long time ago in a galaxy far far away ( I've been playing my sons Star Wars game, sorry) we had a brief discussion on the list about replacing my trailer brakes. I am in the process of doing this so that I can tow my M-23 home in the fall to do major surgery on the mast support system which some previous owner had decided to try and push into the keel, but I digress as I always do. So I took the trailer to the local Trailer Care shop that mostly does horse trailers in the privileged section of Virginia that is the home to fox hunting by the monied class', and I ask the very senior shop guy on check in to put a new brake system on the trailer and say that my tow beast has an electric brake controller so maybe we should go fancy electric brakes. He kind of looks at me a bit askew and says do I plan on putting my boat trailer in water? I say well yea, sensing a trap! And he says well you don't want to be putting electric brakes in water! So there you have it. You were right on. Robbin M-23, M-10 and boy I need a lot more to compete with some of you guys....
