In Chapter 4, what are two challenges the crew faces?

• The beginning of the journey does not go smoothly. The tug line breaks and must be spliced.

• Once out in the Humboldt Current, a cold water current that heads westward to the Pacific islands, and released from the tugboat, no wind comes up to propel the raft. Once a wind does blow, steering becomes a problem. The crew improvises and learns through experience how to keep the bow pointed in the right direction, but then the sea becomes very high from the combined trade wind and current. Fortunately, the raft performs well in the high seas, like a big cork.
