View Full Version : Poll: Should I criss-cross my drain hoses, so my Port bag drains to Starboard?

So, I'm torn. I've been told that if I criss-cross my drain hoses and have my port bag drain on my starboard side and have my starboard rear bag drain on the port side that it will help decrease the passive draining when I'm listed and the drain thru-hull is lower than the top of my bag.

However, the part of me that likes things logical and orderly doesn't like the idea that when I drain the port bag, that the water will shoot out on the OTHER side.

So, what do you all think? Function first?

Function first. I cross vented and it did not take very long to associate the full side vs the venting side.

wish I would have done mine when installing the larger bag and extra fill/drain pump. I also need to cross the vent lines.

Do you mean drain or vent?

Just hit the fill pump a couple times , back to 100%

The only reason to cross vent or drain, is if your listing so hard your ports are under water.

You can also stop this by using 1 was vents.

On my LSV I listed it so hard the ports would be under water and this would cause water to go in the drains, not really a big deal. Just keeps that bag full lol.

When you drain it and its under water, it really doesn't matter because the pump is power full enough to push the water out the bag and back into the lake.

I just don't see you listing your boat this hard Trayson, not with all the work you did on the Supra to make it NOT list when you surf.

I cross vents/drains, when you surf the bag will drain, at least mine did..

Well, right now I have the stock ballast system with 1 fill, and one drain and no vent. When I am listing surfing, the water will drain from my surfside bag out the drain because the top of the bag is higher than the drain thru hull.

For my new setup (still aerator), I'm going to have a drain and a vent line coming from each bag. So I'm thinking it would probably be good to have the port bag drain AND vent to the starboard.

Can't hurt, right?

I would definately drain AND vent to the opposite side. You will get used to it. I did the same on my 2010 OBV.

Make sure you also put the thru hulls as far forward in the rear compartments as possible.

How about you just install Impeller style pumps, then they fill drain under the boat, this helps your OCD, and then Cross your Vents and you will never be the wiser?

My vent/drain thru hulls sit several inches lower than the tops of my bags so leaning = draining... At least until the bags are the same level as the thru hull is. You don't HAVE to criss cross both, just the vent, but may as well do them both to keep your wits about you.

I am going to use the existing "drain" thru hull for the vent. That is located between the crossmember that's between the seat backs and the front of the locker. So it's certainly forward relative to the locker itself.

That said, I am planning on placing the drains through new thru-hulls. I could mount these way further up on the hull. Heck, I could easily go just behind where the speakers are.

So are you talking about mounting the DRAIN thru hull forward? or the Vent? or both? Please expand on what you're trying to suggest for me.

Life would be easier if I'd gone impeller. But I still think they'd be slower. I've set my course, so I'm going to run with it....

Let's not forget that I'm modeling my ballast system after Berg's:


I often stand there, beer in hand, kids screaming, stereo blasting, proudly examining the MASSIVE flow rate of my ballast system sucking the river level down so quickly that guys are panicking and kicking over sand chairs to go push their boats out and reset their anchors. I gaze down the beach for exactly 7.32457 minutes and wonder if any of the bikini clad women on the beach are admiring my system too. Typically when a cute blond in neon pink looks up and starts to smile I snap back to reality, most often from a smack up side the head from an irritated wife or daughter, and realize the rear compartment is popping open and the side wall is bowed over so far it's starting to melt against the exhaust manifolds and the rudder is firmly embedded in the sand; I figure the bags are about full. Okay maybe 95%ish. Time to chug the last of this beer and go surfing.

I admire, and sometimes question, the dedication and enthusiasm that goes into flow testing the different possible setups. But any guy who's bragging about how big his Johnson is,,,, well to that I say

'my pump's bigger than yers'

Your picture of your two different sized thru-hull reminds me of the "surprised" internet emoticon. o_O

I think you need a nose and a mouth on the side of your boat...

Both. My neighbor's old Malibu had all the drains and vents near the transom. When the boat was surfing, and the bow was high, the front section of bags would rise above the thru hulls, and water would drain out. By cross venting/draining and forward thru hulls, no part of the bag will ever be higher than the thru hulls.

Copy that. I had that issue with the vent for my Supra's rear underseat bag being in the stern.

It's a little off, like me.


I'm contemplating going with pirate ship mods and ditching the ballast bags in favor of ammunition storage to feed the built-in 50-cals.

I echo Joe's comments on the rear ports. My originals vented and drained out the back, whether I wanted them to or not.

Definitely cross them, and definitely do both the vent and the drain. In your case, since you're sharing that line, you can combine them and run one hose across the boat for each side.

If you had gone with reversible pumps you could use our double top secret passive drain blocker on the vent line, but since you need to be able to drain through that hose as well that's not really an option.

Seriously this is a no brainer......same side and after you fill a wine cork will prevent any leakage. Yes if it's a new instal or you want to buy lots of hose go contra lateral side but otherwise just cork it.

The problem with a cork is you have to decide if you are a traditionalist that requires real cork or if you will stoop to using an, ugh, I can't even say it -- rubber cork. Alas, aren't the screw caps getting more popular anyway?

How about an LED wine stopper? haha!

After finishing the bottle of wine in order to be able to use said cork, one may forget to uncork upon completion of surfing, which would result in the champagne bottle effect and said cork magically disappearing. Which leads to another bottle of wine needing to be emptied in order for.....

Wait. This proposed setup should work just fine.
