This stone requires you to sail into the vessel with your ship. Once you get on board, you have to fight two bosses (both ghosts). Use electricity, light, or fire and win. The Bluster Blade from the Glittering Grotto is a good weapon, but you can brute force your way (three vs. one) if you so choose.
Jetsam is just a tougher mini-boss, but Cap'n Crossbones has Plunder and Hammock Hack, both which afflict status ailments. Gang-up and put the undead out of their misery and claim the stone.
