Boats, Brains & Brawn

Boats, Brains, Brawn (also known as Rove, Rove, Rove Your Boat) is a recurring physical challenge on Survivor.

Rules
Castaways would paddle a boat out into the water and collect a series of items, either crates or oars, in a zig-zag path going back to shore. Once all the items are collected, they would be used to solve a puzzle. The first tribe to finish the puzzle wins.

History
The challenge debuted in . Paddling out to retrieve puzzle crates, the tribes would have to dive down underwater to release the boxes. Once all crates were retrieved and brought back to shore, the tribes would stack the crates into a staircase with the name of this season "Blood vs Water" properly aligned along the sides. Then, two members of each tribe would solve a puzzle giving them the combination to retrieve the correct key. The first tribe to run to the top of the tower, unlock and pull a lever, releasing the tribe flag, would win the challenge. Galang won their fourth immunity challenge in a row, beating their rivals in a close race.

The challenge returned in  as a post-merge reward challenge, where the teams had to go out in a boat to retrieve paddles with letters on them. The first team to come back with all the paddles and use them to figure a common Survivor phrase ("Worth playing for"), wins. In a back-and-forth race, the purple team of Jefra, Jeremiah, Spencer, and Tasha were able to beat the orange team to enjoy a picnic lunch.
