I bought a used drysuit. Took it to a diveshop to have neck seal replaced. He said, the suit is too old (it is supposed to be a brand new, never used, but aged suit) and he does not want to replace the seal. Anyhow, he said if it leaks, I would "sink like a rock".
So, did I miss something in physics? He said he has taught "thousands" to dive, and has been teaching divers for 25 years. He said that a wet drysuit would weight hundreds of pounds as the liner would take up water. I don't argue with that...
But isn't water neutrally buoyant? So I could lug along an extra 200 lbs of water, and my buoyancy would be the same as on the surface? All I have to do is inflate my BC, and as long as I am not overweighted at the surface due to excess air in my drysuit, I should not have any problem surfacing, right??
If my BC has a buoyancy of 28#, and I carry less than 28#, I should have no problem surfacing, right? If I dump my weight, and even if my BC did not function, I would still be neutrally buoyant - right.... Assuming that my tank is roughly neutrally buoyant?
I should not be sinking like a rock with a wet drysuit, right?
