In Fortnite's Postcard Tour questline this week, you'll need to unravel a confusing quest that only says something about how "three boats bring cargo." That's all the quest tells you, and without quest markers, it would maybe take a while to figure out. With our guide, it'll be much quicker.
Fortnite: "Three boats bring cargo" - quest guide
If you're just finishing the masked warrior made of light quest, you're in luck. Locating the three boats that bring cargo won't take you far. In the water south of Mega City there is an assortment of boats with containers on them and a launch pad. Swim, sword-dash, or glide over to there where you'll complete the first part of this quest.
Remember that for the second part, you must emote while standing on the cargo boats. If you leave without emoting, you'll still have to go back and finish this quest, so don't forget!
