Margie and Luke are now at the stage where they've covered the pig with canvas, and are now using shovels to cover the canvas with sand and sod. They get the approval of a sarong-clad guide, and get their next clue. "Keep your swimsuit on, you're headed for the water," Margie reads.

And suddenly we're at McGregor Point (also on Maui, conveniently), where three personal water crafts are waiting for them off the beach. Each team will drive one a mile along the coast out to a "buoy field," where clues are hidden among 100 buoys floating off the shore. Margie and Luke run back to their waiting taxi, while Jaime encourages Cara to make up time on the pig-prep. Meanwhile, Tammy and Victor realize they're doing it wrong. "They're doing it wrong," laugh a few locals watching from the sidelines. Helpful. The siblings realize they don't need the giant palm fronds on there. "Probably makes it taste gross," Victor says of the pig they've half-dragged across the beach.

Luke and Margie jump back in their waiting cab, still out of breath from the run and the pig-hauling, but not too tired to high-five. Back at the luau, Jaime and Cara have reproduced Tammy and Victor's mistake with the palm fronds, and while they're trying to reproduce the remedy, Tammy and Victor finish up and get their next clue. "That was gross," Tammy chirps as they hurry back to their cab. Team Go Team finishes right behind them. Dude, nobody is getting any breathing room at all in this last leg. It's actually kind of nervous-making.

Margie and Luke spot the old, faded, hand-painted sign marking the access road for McGregor Point, augmented for today by a fresh, bright, Amazing Flag. Jumping out of their cab, they run down to the beach and each put on life vests and aqua socks that have been laid out for them on the beach. They then swim out to one of the four PWCs waiting a fair distance offshore, where the water is shoulder-deep. I assume the fourth is there for rescue if three teams are out there at the same time and one gets into trouble. If two teams require rescue simultaneously, I guess one of them won't be making it to the Finish Line after all. The guide holding the craft warns them to keep the "safety line" on the whole time. As they get going, Luke's trying to point Margie in the right direction, but she'd rather he use both his arms to hold on to her. Some dramatic helicopter shots follow their progress along the shoreline, until they find the buoys. She sort of coasts awkwardly in among them, with him going, "Mom, mom," the whole time until she snaps at him not to yell at her. At least she doesn't threaten to quit this time. The search begins, and the challenge is that they have to lean waaay over to pull each low-floating buoy up out of the water to check for an attached clue. And also that navigating a few yards at a time isn't really what a personal water craft is designed for. It's like browsing a bookstore on a motorcycle.
