Looking back at his fight with Luffy, he claimed that he damaged Luffy because of his Fishman Karate, not Haki, he also didn't use CoA when Luffy hit him with Gear 2 and let his hands be bruised
That fight is weird in hindsight and makes me wonder if Jinbei was meant to be someone who relies more on Fishman Karate rather than Haki, remember this was almost a decade ago and Oda probably hasn't figured out what to do with Haki and who gets it or not
