Frank,
Thanks very much for the comments. Burch's book has the sights, plots and logs from a Victoria to Maui race that he did as navigator. He took quite a few Sun, star and planet sights over the course of the two week passagte. His sight reduction forms are included so I can also check my solutions. I just thought it would be good practice to work through the sights in the book, do the plotting, and see how my answers compare to the solutions in the book.
