Self bailing hull

Do any ribs have a self bailing hull or is it impossible due to tube proximity waterline ect?

as long as the deck is above the waterline it will self bail. All will bail when on the plane, some will at rest.

Gemini Ribs came with a ping pong bailer.
At rest the water pressure kept the captive ball against the drain from the bilge and in motion, pressure from any water trapped in the bilge would push the captive ball back away from the drain and let the water out.

Is this what you meant ?
I took the one fitted to my Rib out, when a piece of paper about the size of a postage stamp managed to jam the ball open and the boat filled with water while on a mooring.

Do you mean hull or deck? And at rest or moving?

Self bailing or Self draining?

The first suggests an arrangement where water is collected from the deck and pumped out of the boat, where the sea surface level is higher than the deck level in the boat. There would be a mechanism involved. Such things exist - someone tell me if they find a good one

The second is a different thing entirely, basically the decks are higher than water level at rest and deck water simply drains out via a scupper or whatever and falls into the sea.

It would be unusual to find a small RIB with self draining decks...

The Redbay Stormforce 850-1050 range can be decked to be self draining.

What I was wondering was if any ribs self drain at a rest and level position without a pumping system

There are ribs that self drain, they are usually bigger boats with more displacement, any boat with a deck above the water line will self drain, this is rarely achievable with a smaller outboard rib

My Ribeye has a self draining deck at rest (just) that when left on the mooring with the bungs left out will drain. You do get a bit of water sitting at the back depending on how much junk I have under the back seat as the drains are just too low to keep it completely dry, but any rail water over this just drains out. If any water finds its way in to the bilges (wet anchor locker) then this is pumped out but the auto bilge pump shifts that.

Inshore Lifeboats have transomless deck. water runs straight off. I guess the deck sits high though. I'm sure it is pretty wet a lot of the time though, not really useful for leisure purposes.
