Classes and Starts

Class splits and start times will be posted and available for downloading on the GPSC website at least one week prior to the first race of a series. Early registration by participants aids GPSC in determining fair and reasonable class splits. A minimum of five boats is required to constitute a class. Consult the website Sailing Instructions for any class changes 1 week prior to the first race. The Sailing Instructions have a revision date on them for the purpose of tracking changes.


Course/Class assignments are set forth in the Sundown Series Sailing Instructions. An illustrative map of the Sundown course with relevant approximate GPSC or Navigation buoy locations is available for download from the GPSC Sundown Series web page race section.

Special Signal for Freighter Traffic

Foxtrot: code "F" flag. When displayed on shore or boat, the shipping channel downstream of channel mark "G1" shall become a restricted area.

The “F” Flag Signal, with an audible alert, will be displayed whenever a freighter or restricted vessel is in the vicinity of the starting line and course. While the “F” signal is displayed, boats waiting to start will vacate the shipping channel. Please note S.I. #1 and #11 regarding GPSC responsibility to the U.S. Coast Guard and enforcement of flag “F”. A GPSC patrol boat will be on station to ensure adherence to these rules by all entrants.
