Default Understanding self bailing

I think I may be misunderstanding how a self bailing boat works, because something isn't adding up when I try to figure out my boat.

I purchased a new Regal 21 OBX bowrider earlier this year. I was told that it, along with every boat Regal makes, is self bailing. That's a big selling point.

I was under the impression that any water that enters the cockpit would travel through the scupper holes in the first picture, and get drained directly overboard.

However I was changing my fuel filter earlier today and had to access the area right behind those scupper holes. All the water that goes through them simply flows down about a 1 foot long length of black hose and get dumped into the bilge.

Am I just fundamentally misunderstanding something, or is this not self bailing?

The dealer confirmed this boat is self bailing when I bought it, and I even called their main corporate number down in Florida and spoke with someone there just to make sure.

I certainly would not consider this self-bailing. To me self bailing means that water won't build up in the bilge if no bilge pump was present.

It self bails....into the bilge! Just make sure you have a good bilge pump and auto switch. Test it often. Mine's not self bailing either! I have a spare 2,000 gph pump hooked up to a bilge pump hose and alligator clips for emergencies.
Self bailing means...the water is sent overboard with no bilge pump needed. What they have there, seems to just make sure the carpet doesn't get soaked!

Looks like either they forgot to connect the hose to the outlet where your scuppers should be or they are completely lying.


Do you even have scuppers on the outside of the hull?

No, that is not a self bailing hull, scuppers would dump directly overboard. Also did a quick spin though Regals' there is no mention of it being a self bailing hull.

The deck level at the drain ports must be higher than the resting water line for a self bailing boat to work. Normally drained out the transom at or above the water line .
If the deck drain is lower than the resting water line. It’s not going to happen.

Yeah that's kinda what I thought. That, or I was really misunderstanding something.

This is really frustrating because being self bailing is a big plus, and one of the things that separates this boat from similar ones from Sea Ray, Chaparral, etc...

It appears that in the brochures, only the deck boats are self bailing. It does not say the 21 OBX is self bailing.

I wouldn't sweat it, most self bailing boats are not self bailing enough. They can self-bail rainwater or wash down from the deck. that's if there's no leaking deck plates and there's usually some. They will not self bail a wave over the bow in rough conditions before the next one comes.

So to be honest it's are not as valuable as people think it is. on top of that, what let's water out also lets water in when that scupper gets submerged. And that water usually finds its way into the hull through a deck plate or something

Good point - just one, which I guess is for the bilge pump.

Right, it doesn't. Which is why I asked the dealer several times, and even followed up with a phone call to their corporate office to make sure.

When I was filling out the post purchase questionnaire, I even said that they should do a better job marketing the self bailing feature of the boat.

i donít think thatís right either...

bilge should discharge through a thru hull fitting well above the water line no scupper needed..

you need to see what is connected to the scupper, if anything
