OK this may not be a bug so much as a quirk, but I've found that when ever I hold space, w, and LSHIFT (run button) I find that I can perform a movement similar to that of B-Hopping, or Bunny Hopping. I'll include a link to an example if you don't know what it is. Basically, I performed a test on my raft on the longest part (19 foundations long and 18 nets) where I ran from end to end and that took me 5 seconds where as B-Hopping took me 3-4 seconds. It's likely not a bug so much as a quirk/exploit (though, I can't really see how one could exploit this). Though another bug I've found which is rather minor, is whenever I try to place a wall parallel to a chest and in some cases a purifier/cooker I cannot place said wall-despite me having more than enough resources. Despite these two VERY minor things, I've found zero game-breaking bugs so far and have found the game quite enjoyable. Good work.
