Brad,
The Raft Book is a great read and does use the Polynesian system of navigation - at least as people knew it in the 1940's. The system included CN but only as part of a " look at the natural world " approach. Birds and fish and clouds over islands and waves and ....
The book came with a world map with zenith stars printed on both sides. One side was like a normal star chart so you see the stars looking at them but the other side has a world map ( oceans unbroken ) with the stars on it mirror image so you could plot a course.
H. Gatty was a world class navigator in the 1930's. Was from Australia and knew the Pacific Ocean well ( He was one of the founders of Fiji Airlines ). He helped the US goverment get a toe hold on several small Pacific Islands and helped teach navigators during WW2.
I do not thing The Raft Book added to the practice of CN but was of value to airmen lost over the ocean and helped them eat and find dry land.
