“Trailing edge technology” tackles the problem of a cruising boat’s fresh water system with breathtaking simplicity. The concept of Yestertech has no better spokesperson.

    Also great for shore camping with a small boat. You could just set it on rocks, or make a simple stand for it as part of a small camp kitchen. I like this stiff jug over the collapsible ones that we used for Boy Scout camping.

    How do you get a hot shower at sea? Salt water? Pressure?

      Not that I would necessarily recommend it today, but back in 1967 my grandfather installed a 30-gallon black plastic tank on the fly bridge of his Pacemaker sportfisherman, which gravity-fed the galley below. We filled it with the garden hose straight from the house tap (which would probably have people shuddering today!!) I would probably not do it today because I understand now, that that 30-gallon tank placed almost 250-pounds of additional weight above the boat’s center of gravity. Not a horrible overload, but in rough seas I would want as much weight as possible down below for stability.

      However – to John’s question about a hot shower – if you put say a 15 or 20 gallon black plastic tank up top temporarily and let it sit in the sun, it would heat up well, and provide hot water for a shower. ( Just be sure to test it before using it in case it gets a little TOO hot!)

      Love the simplicity of this system, and would recommend looking at scientific supply catalogues for nalgene water jugs of different sizes. I had many jugs just like this in my laboratory. The tip about diffused lighting is also a neat one, and yes it really works! It also works with one gallon water jugs in your campsite or tent. (That’s a great example of “Science in Action”, folks!)

    Eric mentions having to rip out stainless steel tanks, under bunks, causing condensation and rot… How about a video about all the things that can go *wrong* with wooden boats (and how to avoid them.) The perspective of those who have to do the repairs would, I think, be pretty interesting to those who own a wooden boat.

    Here in Alaska lots of people (mostly young) live in what are referred to as dry cabins. In an extreme cold climate, any plumbing constitutes a liability since consequences of a freeze-up are severe. What Haddie has done on Vela is standard procedure for dry cabin dwellers. An outhouse serves as the bathroom, and a sauna serves well for bathing, again, with a gravity feed shower, or a friend with a bucket. I’d venture a guess that there are billions living happily worldwide, without running water. Thanks for the reminder that old ways work…better sometimes than newer ways.

    Please do a spot on Vela herself! She looks to have all the charm and grace of a simple life.

    Friends who weekended on a Stone Horse got 3g jugs from Poland Springs, with the little spouts on ’em. They’d freeze one all week in the home freezer, and it’d be the ice-block for their icebox for the weekend. The melted ice-block from the PAST weekend was the water supply for THIS weekend (and got re-filled and re-frozen for NEXT weekend). Worked like a charm.

    Having just run about three miles of PEX tubing you have me aching for Vela’s simple solutions. I couldn’t help but notice the exposed vented loops in the background too and wish I had all the time I put into building loop cabinets back again to go sailing! Thanks!

    That’s as simple as it gets! Thanks Haddie.
