First new sub of the year for me. She was sent to me by a good Friend and fellow bubble head. Included was a WTC or water tight cylinder which I converted from a gas type to RCABS. Which means, Recirculating Compressed Air Ballast System.

What this does is take the air inside the sealed cylinder, pumped to a bladder in the ballast section and inflates it. This pushes all the water out to sea from that section. This creates a vacuum in the cylinder. A servo activates the pump by hitting a switch in one direction. While moving it in the opposite direction it opens a valve allowing the air in the bladder to escape back into the lexan WTC deflating the bladder.

I use this system on all my subs and it is most reliable. Plus there's not need to worry about how much gas you have to dive and surface. As long as you have batteries you can dive and surface unlimited.

Waiting for the paint and clear coat to dry a few days. Then I'll trim her in the pool and test her extensively before I take her to the lake.

It's amazing how big these boats were compared to the type 7.

Here's the coverted WTC.

Beginning work on the scum line.
