One tribe or team must sink the other's boats. The first tribe or team to do so wins.
In Survivor: Pearl Islands, each tribe had two boats (each with three members inside) and a fisherman grappling hook to help to remove plugs that covered holes along the sides of each boat. The Drake tribe sank both Morgan's boats and won reward.
In Survivor: China, the Hae Da Fung tribe was divided by Schoolyard Pick in two groups, with the last remaining member not competing in the challenge and not going on the reward. One member of each group sits in a small boat in the middle of what is essentially a pool, while the three remaining members of the other team stand on a pontoon and use buckets to throw water at the boat to try and sink it. The first group to win two rounds wins the challenge. The yellow group successfully sank the red group's first two boats and won reward.
