We're Maurna, Nelly, Rachel, and Alisha, and we tried to figure out how to keep our raft from rocking in the waves. We noticed that it moved up and down, and side to side. We first tried using an anchor. That didn't exactly work, because even though the raft didn't drift, it still moved up and down with the waves. When we tied on more anchors, we had a new problem: our raft got swamped with water! Do you have any better ideas?
