You can’t supplement it with your urine, because your urine will be containing the salts you’re trying to get rid of.
If you had an ample supply of urine from someone who was extremely well hydrated, maybe.
But yeah no you shouldn’t be drinking seawater at all, it’s just too salty. You’re expending more water of get rid of the salt. Coffee or tea would be fine despite slight diuretic effects, but ocean water is just too salty.

You won’t die immediately, but there’s no way that consuming 35g salt/day won’t lead to severe health issues down the line …

Yeah, you’re right, it was some really shotty early morning math, I was thinking 100 ml not a whole liter.

The outcome of your typo ended up being really interesting though!

35g of salt can be a lethal dose for a human of about 70kg, so no one’s going to last too long on this diet.

LD50 for a human of 70kg is 210g (3g salt per kg of human), so it seems rather unlikely that it will be lethal short-term (though always possible). It mostly becomes lethal when you don’t have any water that’s actually hydrating.

I think you may be thinking of the LD50 for rats. People have died from much less than 3g/kg.
