They say a rising tide lifts all the boats, but in Fortnite it seems to be moving them too. The yacht has been moved by flood waters and can no longer be found in Steamy piles. The yacht is now located to the north of the map, right in the middle. You can see it marked on the map below.
The yacht has also undergone some pretty dramatic changes. There are no more minions to be found, although various references to Deadpool have survived, as he launched Meowscles last season and took over. You can still find art and Deadpool's mighty chair, but the safe is gone. The door is just open now, and it could contain a loot box, but that's it.
The yacht is not a great place to land, for two reasons. There are a lot of chests and ammo boxes here, so you may well get looted before you go. There's also a reboot van for Duos and Squads players, so if you lose someone in an early skirmish, you can bring them back.
You can also find a loot shark here, so if you want to ride one, just grab the abundant fishing rods that will appear on the yacht and catch it like you would any normal fish. Finally, there's a helicopter, so once you're done here you can easily access any other part of the map, making it a solid and viable stopping point, as you're never really that far nowhere else.
