I have a JetDock floating dock for my little boat. I've configured the cubes several different ways, but no matter how I do it (with the cubes I have), the back of the boat dips in about 2 inches in the water. Ideally, I don't want any of the boat to be touching the water. The JetDock solution is an air assist system where you are basically inflating a bladder that is held under the back part of the JetDock which lifts on the back of the boat. They charge an arm, leg, 3 fingers and some nose hair for it.
I have a couple of extra cubes that have holes in the tops, and I have pressurized air running to where the dock is.
So, I was thinking of essentially cutting out a section of each of the extra blocks tops, connecting them inverted to the bottom of the back of the jet dock and running a hose to the bottom of the two blocks from my air source connected with a valve and another hose connected to the top of the two blocks to a valve that vents to the atmosphere. So, when the boat is on the JetDock, I close the atmosphere vent valve and open the valve to the compressed air. The air fills the cubes displacing the water out from the holes cut in the blocks tops (which are oriented to the bottom now), and the air filled cubes give the added ballast to lift the boat high enough. When I open the atmosphere valve, the water should enter the cubes from the bottom and force the air out through the valve causing the back to drop.
The question is how to connect the vent hose to the cube with a tight fit so the air isn't always leaking out.
My thought was to drill a hole the size of the threaded side of a 1/4 NPT connector and use a rubber o-ring and a nut to connect. Any better suggestions?
