Is there an exploit allowing to go through the floor of the sloop to the cannons?

So I'm just wondering because the person that I was just fighting was going through the wall to the ladder that I'm aware is possible but he was also going through the floor next to the stoves on to the cannons and I never heard of this bug/exploit that would allow for that and can't find anything online so just for my curiosity I want to know if I fought an exploiter or just some loser

(I do not have a video, screenshot or his nickname as I was to annoyed to think about doing that so I do not plan on reporting that anyway and If I get perma banned on this reddit for this question so be it)
