This is one of several player-designed bedwars arenas on ObiWorld SMP. This one was designed and built by Karateka8. The map is best suited for minimum of 3v3 and max of 4v4v4v4, maybe more if you don't mind it being crowded.

The attached schematic contains about 5M blocks. You will be standing in the center of the middle island when you paste. You'll need at least 100 blocks of space above you for the lobby and the ship masts. Have fun!
