Check out my answer:
1A sheep and a tiger, and the sheep returns. "Put the Boat Down".
2Two tigers passed, and one tiger returned. "Put the Boat Down".
3Two sheep passed, and a tiger and a sheep returned. "The Key".
4Two sheep passed, and a tiger returned.
5Two tigers went over, and one tiger returned.
5 Two tigers passed! "Done".

It can be said that it is: load the ship together and go straight over, as it was said upstairs!
