I can't wait because as you know, the vis is real good here and can see things coming sooner than later. The barge company that transports all materials from the mainland to the Islands lost about 14 shipping containers just before it pulled into the port of Hilo and they drifted for a bit then sunk so I am going to see if I can find any of them. I called the insurance company who now owns them and they didn't really seem to care if I retrieved any of them or not.

<div dir="ltr">Hi Rick,</div><div dir="ltr">Are you compensating the thrusters and arm from the same regulator? I would caution you on doing that. I have a theory that putting multiple items on one scuba regulator will not work if there is any distance between items. My arm as I mentioned is working well with the scuba reg because it is literally a few inches from the manifold. The hose connecting the reg to the manifold is 1\2 inch ID. This is the reason I am testing an LP regulator, because I can create as much over pressure as needed to help with distance between items. I agree with Alan, that the water should not get to the motors on the surface, particularly if you have some vertical line right off the reg. </div><div dir="ltr">It is sounding like there will be a launch soon?</div><div dir="ltr">Hank</div><div><br></div>
