A
compass and depth gauge are items you need to have anyway, not just for racing. The other items are more or less in the order I find them useful for PHRF racing. If you don''t race or sail at night, the AWI is pointless; you can get a masthead fly for $30. If you''re racing one-design, or against other boats of your same type, the knotmeter is less useful because you can judge your speed against the other boats, or use the
GPS. Lots of variables in sailboat racing. Makes it more interesting.
