What is a Predicted Navigation Regatta?
(‘aka’ Predicted Log Race)

it's a navigation contest where each skipper (contestant) attempts to accurately predict the time it will take to navigate a specified course in their boat. This involves the precise calculation of the time in hours, minutes, and seconds required to cruise a prescribed course. The course is described with ‘true headings’ and ‘distances’ in nautical miles for each leg. Once the skipper (contestant) makes his/her calculations and fills out the “Predicted Log”, he/she then navigates the boat on the prescribed course, using only a compass and the boat's tachometer (RPM gauge). The winner is the skipper who can predict the time with the smallest percentage error.
