Distances between the club race marks are provided in the following table. The overall distance for a race can be approximated by adding the leg distances.
|HdGYC CLUB MARKS (distances in nautical miles)|
As an example of how to use the table, consider Race 4 of the 2016 Summer Series, which had a Spin course posted of BEZ2, and was started from the dock, at Z. So the individual six course legs are Z to B, B to E, E to Z, Z to B, B to E, and E to Z. From the table, the six leg distances are: 0.23, 0.84, 0.61, 0.23, 0.84, and 0.61 for a total distance of 3.36 nm.
