Water heater heck.
Tim and all, shortly after buying the Dawn Treader almost 13 years ago, I planned to replace the water heater but decided totally against it in the long run. My E31 was them powered by a raw water Yanmar 2 and as such, couldn't really get any heater really hot with fresh water. When I removed it, it had that familiar sound we've all heard from our youth, that of a shattered and leaking Roy Rogers Thermos bottle. There's nothing that can replace the sound of milk and broken glass sloshing around in your matching lunch box. I had to remove the cheap outer skin to get it out over the engine and in the process of getting it out came to realize that it was 110 volt only, now a silly waste of space as all I had to do in the slip to shower was to go up the gangway and there were lovely showers there. That space has long since been rebuilt to accommodate two dedicated #27 batteries that run the Adler Barbour unit. If I want to shower when at Catalina Island, I pour 3-4 quarts, yes quarts, of fresh water into my 1 gallon (really 1.5) stainless steel Hudson sprayer and heat the contents on the propane stove for five minutes. A quick spin on of the the top and a few short pumps and that's all it takes to provide perfectly heated water, enough for the two of us (separately) to have a Navy shower including two shampoos each with a bit of water to spare. If it's been left on the stove too long and is too hot, a mere twisting of the nozzle tip atomizes the heated water and it's just right again. My next door neighbor is a recovering plumber and with his help & pipe bending tools, the brass sprayer wand is now U-shaped so squeezing the handle delivers water right back at the user. I stow the empty sprayer with lid off behind the wet weather gear in the hanging locker when not in use and it virtually takes up no room at all. Why not use a Sun Shower you say. The big difference is that you can be showering within minutes of the inspiration and you can do it at 0600 too. Later, Glyn Judson E31 hull #55, Marina del Rey, CA
