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: 0.24, 0.83, 0.59, 0.24, 0.83, and 0.59 for a total distance of 3.30 nm. The club computer calculated the course distance as 3.32 nm, using more significant figures in the computation.
Coordinates for club marks set for 2016 season are:
Z: N 39 degrees 32.771′ W 076degrees 04.936′
G: N 39 degrees 32.541′ W 076 degrees 04.500′
H: N 39 degrees 32.908′ W 076 degrees 04.425′
F: N 39 degrees 32.599′ W 076 degrees 03.693′
