Thank you much Chris. You are correct, there are no valves anywhere that I can find on this boat but then I am not sure where to look. The hull number starts with HMS so it came up as a Halmatic on the licensing system. I received no documentation at all with the boat so your information and web site is very much appreciated.
So do you think the tubes are solid foam or foam over air tubes like the ones on your web site?
The covering on the tubes seems sturdy and thick but real rough to the touch. It was obviously painted black at one time but the black paint as come off in the areas where the sun can get directly at it. It looks like it spent most of it's life on a trailer. The exposed orange tops of the tubes have a very rough feel with bumps and voids similar to the way we texture walls in homes here.
I'm hoping to continue to use the existing tubes as it will continue to be a work boat so it doesn't have to be beautiful, just reliable. I was thinking of painting on the "liquid rubber" from www.inlandmarine.us
to smooth the surface out and then applying their topside paint for UV protection. I wonder if this is the right way to go?
In the event that I need tubes or new fabric, how much do you charge for the templates?
I still haven't been able to find another picture of a boat like this. Anyone with ideas or suggestions would be welcome.
The boat is amazing, it starts right up and we hit 35 knots top speed although there was a pretty fearsome shudder just before the turbo kicked in as we were coming up on plane.
It is a very interesting project. I am going to take it out on the Columbia river today, maybe catch a salmon before they shut the season down.
