I have found the white seed ship.
A walktrough keeps telling me revisit edea (WHERE?) and to talk to the guy in the cabin, but he always kicks me out, and says i have no proof that edea sent us.

Also any strategies on beating the tonberry king using the gf's:
Siren (lv 96),Diablos (32), cerebrus (34), Shiva (64) and characters;
Squall: 66. Quistis: 38 irvine: 36.

Get the letter from Edea. Go to the White SeeD ship then. There is a cool easy money trick here. Sell the letter that Edea gives you and come back for another. They sell for 100 gil.

That's not a "cool" money trick --- that's the dumbest Final Fantasy gil-making trick of all time.

As for Edea, she's in the orphanage (you do remember where that was, right?) Head in and then forward and then follow the path in the room until you come to the area with her and Cid, talk to her to get the letter.

^ i went inot evry room, there was no one there, only a curaga draw point.
EdiT; don't you hate hidden exits.

Then that means you missed the way. You probably went straight ahead. You should be able to turn left there when you first enter the orphanage building. Just look for the way and you'll find it.

its on the eage of a little island thing u cant miss it it is a light house thing

Actually it is kinda easy to miss.

wow i didnt know you could sell Edea's letter
