This is a a small survival challenge, similar to sky block. You are trapped on a small boat, with limited supplies and must learn to live that way. You can play on any difficulty (normal is recommended) and you MUST play in survival. There are many secrets on the boat, so keep looking! Feel free to muck around, and to be honest I don't care is you go into creative and blow it all up! Just have fun!

Optional challenges:
1: Find all the secrets
2: Reach the bottom of the ocean
3: Build an island (use the grass block to make it more natural)!
4: Build a cobblestone generator!
EXTRA HARD!
5: Play it on hardcore mode in hard difficulty on your server with PvP enabled!
Who would actually do that?
