Since i also did quite some seal hunting recently, i cannot keep myself of putting in my own 5 cents...
I will also try to explain some of the seal's behavior i have observed so far.
First and most important point is: You have to commit to it. Doesnt matter which hunting tactic you use, dont assume the animal is gone when it's just under water. I am
almost for sure that seals dont dive away under the player WHEN the have an area to escape UNDER WATER.
However, if it gets cornered, say at the beach of a bay, it WILL dive under the player.
Knowing this, you can somehow "exploit" its behavior(i dont actually se it as a cheesy exploit, because i think of it as realistic).
Doing this is not really easy, but once you understood how it works it can be done with a good success rate. Basically as in normal hunting, and by no means with 100% success. But 30-50% should be doable, and well worth the effort.
To get in a situation, where the seal has small chances, you have to:
1.: find a seal
2.: find a small bay
3.:Get on a boat and "drive" the seal into the bay(unless you found the seal in the bay already, which is certainly the best scenario).
Try not to push too hard at first. A seal has some kind of learning behavior and
will become more careful towards the player after attacking attempts. If you scare it too many times, it will start to dive under water even at the edge of the screen, making it almost impossible to catch.
The seals are curious beings and somehow quite intelligent. It will sometimes swim towards you, and if you dont back up, it will escape and dive.
So, basically what you have to do, once you have it cornered in a bay, is try to get as near as possible without scaring it(Move only towards it when it has its back to you) and land a Spear or bow hit on it, when it is on land. I cannot provide any data wether bow or spear/javelin is better.
Bow seems to be better, because you can land effective shots from much farther away.
Now, after your first attack, you will probably not kill it.
No matter if it got hit or not, it will most certainly dive again.
It is very important to row your boat out of the bay now! If you dont, the seal will dive away under your character and be gone.
Drive away now, until you are at the entrance of the bay, then drive in carefully. Most of the time the seal will be on the shore in the bay again, licking his wounds.
Repeat the process, and
keep your distance until you brought it down.
That strategy should leave the seal little hope of escape, and after some hours you can probably get it. I never target legs, since the probability of missing is that worse. Immobilizing can be a strategy, but for seals i chose fatal wounds, to get them unconcius or even dead.
A lame seal will just as well dive and be invisible. Leg hits will surely wear it down, But many of them will damage the fur more, in my opinion.
Most of the time it took me 2-3 hits on the torso to drop it, and the fur always was decent. Also, i kill every animal thats unconcious with blunt attack of the stone axe on the head.
However, it can sometimes be useful to hit the legs when the seal has some ground to cover before it reaches the water and you can then sprint up to it for a melee attack.
Keep in mind that this is neither proven the only nor the best strategy. There is still a Sh* load left to be learned about seal hunting.
I also see sneaking up to them in cover as an effective way to get close and land a critical shot, but it has the downside of the seal escaping into open water. You can of course design your attack the way that the seal will escape more into a bay, but it could swim out if you dont get on your punt quickly and "seal" the bay off.
You have to adapt to the situation, and try got get into the seal's head.
And you have to really, really digest that frustrating failing attempts...
Good luck in hunting and in the new year to all of you!
May 2021 not be so shitty. At least that stupid noises and explosions have been forbidden in our country. Ow, now i made myself some enemies
