I made some use of it today on a 4v4, I had a double carronade side Galleon with a harpoon on it. Had moderate success with it, including a time where I pulled a Mobula's gun arcs away from an ally by poon'ing its wing. I still don't understand the 'rope physics' they look silly and completely inconsistent, 2-3 times the poon'd ship ended reeled up behind me and made turning completely impossible, even though that ended up with them against a wall and me squishing them against it, it was detrimental the other two times it happened.
