Its getting deep,but I love it. Makes my day go faster.

don't call me an airhead... i've been googling and ask.com'ing, nothing so far but i'm not giving up. yet.

There are 4 members looking at this thread right now....everybody must be bored out of their freaking minds...

besides, when does c-rig have 20lbs in the well?? ha ha ha ha

it's been a few months haha.

I agree, lowrider.....the whole premise of this thread is based on unrealistic parameters. All of our theories, suppositions, and calculations are bogus.

[cassidyta]

I believe you also have to factor in barometric pressure in your equation. If I am not mistaken, the 14.7lbs per sq inch is an average. The higher the pressure, the more dense the molecules of the air are together. The greater density would throw off the PSI measurement.

Additionally, the water itself will displace differently. Brackish and warmer water will have a lighter weight than fresh, colder water for the same density based reasons.

Now, I believe that the weight of the fish should be something of a constant because it will not vary enough to change the results during the course of the day.

Mississippiboy I think we are just waiting to see what comes up next, and yes slow day in the tire shop.

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?

[jcw1503]

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.

that should be on a t-shirt

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

[carolina-rig-01]

anyone else have a headache now?

[jcw1503]

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

[1/4 stick]

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.

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

[nofearengineer]

Guys...I'll add my two cents.

A bass, being a water creature, can effectively change its gross density by way of its swim bladder. Yes, it can float upwards (lighter than water), or sink (more dense than water) as it chooses, but the difference between its density and water's density is very, very slight. You will never see a bass doing an "emergency blow" and popping out of the water on buoyancy alone. For all intents and purposes, a bass is like water in a fish costume.

The question is more appropriately asked:

If I take 2 lbs of water from the lake, and pour it into my totally full livewell, so that 2 lbs of water overflows, and runs back into the lake, does my boat sit any higher or lower in the water?

The answer is obviously: no difference.

Now, if that bass, already in the livewell, were to somehow super-expand his bladder, such that he now takes up the space of a 5lb fish (I thought this was only possible in my fish stories ) then some more water would drain overboard, and the boat would sit slightly higher.

If he then shrunk back to his normal state (when you have to show him to your buddies), surprisingly, the boat would not go back down. (Unless your boat has an automatic livewell topper-offer )

Since everyone finds this stuff so enjoyable....

A new question:

You are sitting in your bass boat, floating in your backyard swimming pool. You are holding a bowling ball. You drop it over the side into the pool. Does the water level in your pool go up or down?
