Because I never found them after our sloop battle I just wanted to post here to thank this random player I met today for showing me how to have a fun pvp battle. I can't remember the full name unfortunately but it was hen something (I'm awful with names). If you ever see this, thanks! It is rare to ever have a game with people just leaving you alone and even more rare to have people cooperate with you.

You can try checking your recent player list and figure out the name that way.
That will potentially give you the opportunity to send them a message and possibly strike up a friendship, and if not at least a valuable short interaction once again.
If not I hope your message in a cyber bottle finds them for you.
