The Legend of the Chimney
There is a notorious low area on the north side large basin that has abruptly stopped many boats and damaged more than a few keels. For decades, the area has been referred to as "the chimney". After one such incident at the 2018 Glow regatta, the issue was submitted to CLSA members on the CLSA Forum. You can read the entire conversation here. CLSA member Jim Westervelt took matters into his own hands and mapped the area with a Deeper GPS enabled depth finder pulled about 70km by a boat. The Shallow Areas in the Main Pool (shown above) is the result. If you'd like to read more about the legend, you can read Jim's article published in the Windword Newsletter.
