An idea

Can the R&R set up with an internal cylinder be converted into a LPB/Snort?


The float activated vaccum relief valve is converted into vent valve using a NC solenoid valve ( V).

An open pipe connected to the outside to serves as a water intake /exit.

A snorkel (S) connected to an airpump (P) is used to blow ballast.

I assume you're the same person posting on FB. As was the general consensus over there, perhaps yes you could convert the R&R unit to what you're talking about, but the real question is why. The system is simple, robust and works exceptionally well. Reinventing the wheel for the sake of reinventing it is not a good enough reason.

What, specifically, are the drawbacks you're trying to overcome by adding the complexity of SNORT?

Same guy.
Just want to copy the R & R style of a ballast tank within a single cylinder as opposed to one with segmented sections/ internal bulkheads.
I want to know if there would be issues particularly with venting the tank as the air and water has to travel through narrow pipes. Unlike the current WTCs the vent and flood holes are the thickness of the cylinder walls.

You could just build one and see what happens

Okay, I think I'm following you. You're not modifying an existing cylinder, you're buying or modifying one of your own. Will it work? I can't see why not.

Totally get what you're doing, headed down the same path myself. I want the ballast tank area to be an open chassis area to perhaps allow for a couple of different ballast tank sizes. I will run the wiring under the tank,not through it, making wiring easy to install and modify. The tank would be simple to construct and would eliminate a couple of parts and water-tight joints. I have reworked a few cylinders by various manufacturers and have developed a deep, deep loathing for the tube through the ballast tank method. I have wanted to do this for years but don't have the skills needed to fab the chassis this way and want control of the design "in-house". Learning CAD and 3D printing is finally making this possible for me. I am putting an R&R in a boat now and it's pretty great, just need to lose that damn tube!

The R&R system has a high resistance path for a snort system to vent/flood the tank.

If you want a snort equivalent then you need to pump in and pump out, and remove the snorkel valve. You will then be able to fill the the entire tank, but won't be able to pump out whilst submerged.
