This ''Exploit'' has been in the game for almost 2+ years now ever since it was discovered in the Hourglass Galleon Meta.
You can play in water and chuck blunderbombs and throwables (Blowdart to!) through the back of the galleon hull as if the wooden visuals didn't exist. Basically there's no collision mesh from my understanding, essentially making it that there is no hitbox in a particular spot meaning you can disrupt the bilge and the player grate bucketing whilst being outside of the ship. The damage and knockback effect has the exact same full affect.
You can get oneshot with a combination without ever having to step foot on the ship.
This is clearly an exploit and I will find it damn hard to be convinced it's intentional as it makes no sense.
