dumb question

i agree that we are thinking too hard about this but it was fun to get all the "smart" people at work scratching their heads over this question.

Noone said that some of the water is lost through the overfill drain. It is really simple if you negate the loss of water to the overfill drain. It doesn't matter if the fish in the water or not. If you add 30 gallons of water to a livewell and then add 20 lbs of fish to the livewell, then you have added 30 gallons (~240 lbs of water) plus 20 lbs of fish. It doesn't matter whether the fish are floating or sinking or how much air is in their bladders. You have added 260 lbs of weight to your boat.

Correct me if I am wrong but if water is displaced and drained from your boat then some of the water weight is no longer there....however it just depends on the mass of the bass that decides how much water is displaced.

anyone else have a headache now?

yeah that's way better than the shirts that say "does this shirt make my bass look fat".

I hereby patient the idea...anyone want to go into business.

Me thinks if you aint swiming after you fill the livewell, salright...on a steeck.

Jeff Dunham???? On a Steeeck

i think ya'll forgot to think about the amount of water that goes out due to the fish coming in. incoming fish will release some of the water right?

and ya'll ALL have too much time at work. geesh, i work outside, in a truck or with a shovel. ya'll are making me wonder what your bosses would say if they know what you all were doing on THIER time, hahahahaha. jelous.....yes i am.

i was off work today so i guess the rest of these guys have the explaining to do haha.

I don't have any math classes this semester, so this just counted as my daily mind blowing.

Ok, I just kind of skimmed, but C-rig, if a fish you put in your livewell takes up X amount of space, then X amount of water will be removed from your livewell. when you're talking weight, if that same fish weighed Ylbs, and the water it displaced weighed Ylbs, then the weight would stay the same. if you fish weighed more than the water it replaced, you'd gain weight. And if the fish weighed less than the water is displaced, you lose weight.

As for the weight of air: it is VERY hard to get the exact weight, because of the large mixture of elements in the "air". If we were speaking just oxygen, it's be easy to figure out. but the air contains mostly Oxygen and Nitrogen. But it also contains Hydrogen, Argon, CO2 and some more stuff. So it'd be very hard to tell the exact weight.

The reality is its a matter of density as compared to displacement of water. Drop a three pound lead weight into your livewell, yes you are almost three pounds heavier, the water displassed will be a matter of ouces and very few at that. Air does not displace density nearly as much as water, think of gravity, we weigh 165 on earth, a fraction of that on the moon. There is for sure a formula for the actual wieght added pure fish wieghed on a scale and added to your live well but it will for sure be much less then the fishes actual weight.

yes but a 3lb piece of lead would not displace near as much water as a 3lb fish because it is not near as big. so wouldn't this also be a matter of displacement?

this is zactly on the money. a 5 lb rock is a 5lb rock weather its in the water or in a tree. the gravity in the water olny makes it seem lighter

but the 5lb rock would sink to the bottom, thus touching the boat. a 5lb fish would be suspended in the water and not touching the boat so are you actually carrying the weight of the fish? not disagreeing, just wondering that's all. man it's funny how long this has been going and how many people are stating opinions on it.

The water is in fact supported some of the weight of the fish. However, the livewell is supported the water and the boat is supporting the livewell. SO the BOAT would see the additional 20 lbs of weight from the fish (excluding any water lost due to the overflow valve).

There you go with that faulty 20 lbs supposition again...

LOL
No kidding! let's be a little more realistic with our numbers here... LOL

Ok if you add the fish to the live well the weight of the fish will be added to total weight of the boat minus what ever water runs out the over flow. I'm not liquid pychologist and I didn't even stay at a Holliday Inn Express last night but weight is weight. There is no way to negate it unless you start throwing stuff over board. It's kinda like this. If you are standing on the back of the boat and pee over the side does the front of the boat sink lower in the water?

Bingo, zactly, right on the money

Using this logic, if you paint a room in your house does it get smaller

Good q, by the principal of gravity the weight of the water pushes every infinitesimal speck of the boat downwards the equal amount of its weight (240lbs). And the water pushes back up with the same force as the weight of the boat and its contents. By a major principal of fluid dynamics something will not sink in water unless it is more dense than that water, but that doesn't mean that it isn't adding weight. You would at that point add the weight of the bass and the weight of the water to get the total weight in the live well. Technically though if your livewell is at full capacity at 30 gallons and you add 5 fish the volume of the fish will displace the same amount of water as the fish have in body volume. Since the fish are composed of about 70% water, like humans, the other 30 % is lighter than the water, therefore by adding some nice bass you would effectively lighten the load on the boat hull as compared to just water in the livewell, this being said, it wouldn't be much, but it may help you get back to the weigh in a second or two earlier.
P.S. Sorry, Im kinda nerdy for a bass fisherman, but I feel that it helps me on the water cuz I analyze everything
