PTSA Marks and Their Labels, revised 2013
Roundings: Marks are to be left to Port when rounding unless the letter on the letter board is underlined and striped, in which case that mark is to be left to starboard.
S Start, specifically the Start/Finish line i.e.; if the “S” is underlined and striped, then you will start with the pin on your starboard side and the committee boat on your port side. The default, however, is to start with the pin on your port side.)
F Finish, specifically the S/F.
2 Go around course twice. You must cross the S/F line each time around. (This is the only time it is okay to cross the S/F line during a race when not starting or finishing.)
The following marks are usually yellow tetrahedrons and commonly used for triangle and windward/leeward courses. They may also be used to provide a shorter course for the small boats or a truer (to the wind) course for any class. They could be set up anywhere in the bay.
W Windward mark
J Jibing mark
L Leeward mark
O Offset mark

|H||Temporary mark off Fort Townsend dock||N48 04.690||W122 46.947|
Please Note: Temporary tetrahedron mark in the vicinity of the ferry dock is placed to aid in keeping clear of the dock. Mark must be left to shore ward unless indicated as a rounding mark on the letter board. Independently of the presence or absence of a “D” mark, all racers are to keep at least 100 yards clear of the ferry and ferry dock at all times (even if the dock is empty).
*GPS positions are all approximate, due to wind, current and depth. GPS for temporary marks are VERY general. GPS positions are given to give you a general idea where the marks will be, if you are not familiar with them.
**The red Pt Hudson bell can buoy #2 is to be passed on the outside, or left to shoreward, if it is not a mark to be rounded. If you are rounding it as a mark, then the letterboard will indicate which way it is to be rounded.
