namor has to make Batman's position first.
Batman has perfected the art of dissappearing at will against
Manhunter [telepath], Superman [enhanced audio diagnostics] The Millitary + Local Law Enforcement
Namor's strength gives to Batman's stealth, hypersonics and hulk busting Bat-kick

Batman with prep, though a teeny-weeny bit tiring by now, is usually enough to let Batman stand his man with the big red S - unlikely, I know, but that's the way the comics are written.
Therefore, I conclude, that Bats with prep would AT LEAST be able to stand his man against Namor, even though I concede, again, that by all laws of probability it should be unlikely, to say the least.
But Batman, with prep, would probably come up with a concentrated de-humidifier, quickly sapping Namor of his strength, - or, even more likely he would just run to Clark and ask him to come save his sorry butt - hey, a win is a win
Actually, I'm a bit of a Bat fan, so even though I know somebody is gonna try and bite my head off and I'm gonna go ahead and say it: Bats, with prep, has about as much chance as he would have with prep against Superman.
Without prep, he'd be swatted away like a bat hit with a tennis raquet...
stick thin david with catapult and pebble>>>>> Armoured, Armed Alpha Male Goliath, fortified with super strength and bloodthirsty minions.
ripped Bat with advanced tech and sleight of hand>>>>>>>> Alpha male atlantean with super powers
consider this: YOU! unarmed w/o prep or back up, given basic training and Heightened Intelligence, Awareness & Street Smarts can disable the US millitary machine
The mistake you are making is that you are looking at this from a purely linear (and therefore myopic) perspective.
Batman, as you said, is a human (although some of his feats are not ....although that is probably an inside joke at DC where their 'humans,' eg Batgirl and Batman, regularly pull feats that are anything but). Anyways, Bruce is 'human.'
Consequently there is NO way he can go an engage a superhuman directly.
No way.
However he virtually never does that. You will not see him going toe-to-toe with a meta, or trading blows with a Daxamite, or engaging a blood-lusted Kryptonian head on.
Never.
He will always use some oblique form of engagement that either magnifies his chances of winning, or negates the other character's power sets and attributes. Usually a mixture of both.
Thus it always strikes me as dumb when posters automatically assume that Batman will simply waltz up to Superman, Aquaman, Namor or the Hulk and go into a Gung Fu pose and try the Crane form against them! Or that he will go to WonderWoman, Thor, Namorita or She-Hulk and try to see if a punch will faze them!
That is (pardon the expression) simply dumb!
Batman engages from an oblique angle, capitalizing on the other character's weaknesses or flaws, employing prudent stratagem against the other character and, in essence, turning their very strengths into veritable weaknesses and, consequently, their downfall. A good example of this is when Batman faced Superman in Hush ....it shows how Batman used the powers of Superman against him to great efficacy.
That is what makes Batman special .....the fact that he is human, and through sheer will and ingenuity is able to bring down forces FAR beyond him. This is why of all characters in the JLA Batman is the most 'super' (in some ways he is more of a 'Super Man' than Superman), and this is because he embodies what is great in everyone of us.
The ability to rise up beyond your circumstances and limitations and bring to fruition something that should be 'impossible.' This is what differentiates us from animals by the way .....the ability to reach beyond our limits.
This is one reason, for example, why humans started to use fire, to use tools, to become the most lethal animal (after plasmodium carrying female Anopheles mosquito) on earth, even though we are also one of the weakest, slowest, most fragile.
Yet we regularly killed sloth bears, killed marauding leopards, killed Cape Buffalo that could slaughter an entire village of people. We killed them because of our minds, and because of our will.
Yet in terms of strength and ability we are weaker than virtually all of our animal foes!
In the same way that a hunter will not go and hunt a man-eating Tiger with his bare hands, Batman will not go against Namor with his mere hands!
That would be suicide.
Thus it always strikes me as dumb when people assume that characters like Batman, Black Panther, Midnighter or even people like Doom and Reed will go against characters like the Hulk and Superman head on and hand to hand! While some like Doom 'technically' can (he has been shown going against the Hulk head on), even he wouldn't do so in a KMC-based scenario because there are far easier (and FAR safer) ways to do the same.
It is sheer lunacy to expect a character like Batman (and his analogues in DC and Marvel) to go H2H against truly 'super' characters. They may go h2h against a group of human thugs, but even in such cases Batman normally relies on 'force multipliers' (against thugs, for example, capsules containing disorienting gas, or in the case shown in Hush a database connected to his cowl that enabled him to know the weaknesses of the thugs he encountered. BTW, if he has a database on common thugs that enables him to know that so and so had his ribs splintered some days before, then imagine the files he has on CREDIBLE threats like Superheroes! Consider that he has robust dossiers on most super hero villains, and even has files on his OWN team mates in the JLA).
Anyways, can Batman defeat Namor H2H?
The answer is simple: H#LL NO!
Not in a million years.
HOWEVER, Batman is not the type to go and trade blows with a meta/mutant/super.
