<p>Kairoseki has no effect on haki. Rayleigh could use Haki while being chained in the auction house ( during the sabaody archipelago arc).Also haki is inborn quality in every living thing in one piece world as said by Rayleigh. And kairoseki only affects devil fruit users. Non devil fruit users are not affected by kairoseki. So they can use haki however they like still being chained.</p>

But was rayleigh shackled with kairoseki, as far as I know rayleigh doesn't have a devil fruit power so he probably went for a frail old man and doesn't had kairoseki shackles.

@Wouter as far as I remember I think the giant with him did say something regarding the chain. Also, later Rayleigh explained that all living thing had haki ability so kairoseki might not affect. Kairoseki is mentioned as hardest substance and property to subdue devil fruit powers. Its effect on haki isn't mentioned.

Yes. Rayleigh doesn't have any devil fruit power. He swam through calm belt to reach amazon lily. If he had any devil fruit power then he couldn't have swam through the grand line.

Kairouseki does seems to prevent Haki to be used. Rayleigh was only able to use it because he was the vice Pirate King and has a training level beyond the conceivable in the manga storyline so far, a level Luffy is currently struggling to achieve. But everytime any other haki-enabled user was arrested with Kairouseki, their Haki skills wore off. Happened specially with Luffy, as we can see in chapter 936 where he uses Haoshoku Haki instantly after being freed of the Kairouseki handcuffs. There is in fact no canon saying anything about this, but the storyline evidence is verifiable by exclusion

<p>It wasn't really explained. We still don't know about the full extent of Haki or Kairōseki. Plus episode 627 is a filler so I wouldn't take what happens in there seriously, it is not canon. The anime is notorious for contradicting itself. Oda might explain Haki and Kairōseki more in the manga later on.</p>

<p>As i see it, the Kairoseki (sea stone was a translation i once memorized) makes the devil-fruit user physically weak, unable to move. And as you know, Luffy's ability is pretty much physical in any aspect, meaning when he feels weakened in his body, he also starts to feel helpless in his mind (until emotions tend to make him go berserk). Apparently that's just enough to make him lose his inner cool and not be able to use haki as he wished to.</p>

<p>Just my 2 cents...</p>
