Bit by bit, Ginko lowers himself down to sit in the boat and watch the frenzy from a somewhat safer position.

It's a good thing too, since that means he's actually sitting down by the time Joker hurls himself at top speed onto the boat's deck, so he stays on the boat when he jolts away on reflex. Then he gets a better look at what he's seeing and lets out a quiet, disbelieving snort. "Be careful, there."

He scoots over to lean against the side of the boat again, and hesitantly picks up the fish Joker dropped on the deck. "...You really are something, you know that?"

Ginko isn't sure he'd even be alive by now if this merman hadn't taken it upon himself to help him - and he's still not sure why he's doing this. Sure, Ginko helped him off the boat that first time, but this seems like... a lot, in comparison to one incident.
