This challenge is an easy one to knock out as you can leave the match after getting in a motorboat and re-queue immediately!
So then comes the problem of where are the motorboats in fortnite anyway? There are 23 total spawn points for the motorboats in Fortnite and they are displayed in red circles on the map below.
They are spread fairly even throughout the map, so completing this challenge shouldn’t be to difficult.
