I've manged to reverse-engineer the Fishing Boat algorithm. You can use this tool to find out what charm table you are on based on the results of sending boats to the Moga Coast (30p) and entering the items in the order you receive them.
It's pretty basic, but it seems to work fairly well. Let me know if you want any more features or find any bugs. Thanks!
PS, after some more research, I found that the odds of landing on a cursed table, if you make a new character blindly, are about 0.86% (Specifically 562/65363).
PPS: sorry but it's very, very late and I need to sleep, so I won't be able to respond for some time.
