- All racing at THSC will be governed by the ‘rules’ as defined in the Racing Rules of Sailing. ( CYA/ISAF Racing Rules of Sailing (RRS)), the prescriptions of the CYA, and these instructions.
- The Race Committee reserves the right to amend these sailing instructions. Amendments shall be posted on the Race Committee Notice Board for at least one hour before the first start of the race for which they will be in force.
- In the event that there are insufficient race committee crew for any club race, the Race Fleet Captain may call on crew from as many yachts as necessary to make up a race committee.
- It is the sole responsibility of each yacht to decide whether to start or continue in any race.
FLEET DIVISIONS
- Each yacht intending to race shall hold a valid PHRF certificate. We will be submitting club results to PHRF-LO at the end of the season.
- Those yachts possessing a valid PHRF certificate are eligible and invited to participate in ABYC Tuesday and Thursday night fixed course races.
- Any yacht that wishes to race but does not hold a valid PHRF Certificate will be allowed to race and will be assigned a rating by the Club PHRF Handicapper. This rating will be based on PHRF-LO Standard Boat Data with an automatic 15 point rating reduction.
- All yachts must register in order to race. A yacht can change Divisions if she so desires but only at the beginning of a new series for each of the Wednesday night series. A yacht may sail in either division for the weekend races but must register in the chosen division prior to starting the race.
- THSC will run two divisions again this year:
Division I Spinnaker Division II White Sails
- All yachts intending to race shall come within hailing distance of the Race Committee vessel, either before the warning signal for the first class, or immediately after their class warning signal, and report their sail number and receive acknowledgement from the Race Committee. Boats not racing shall keep clear of the starting area.
- Race results will be calculated using the PHRF-LO handicap Time on Time system.
- The Race Committee Reserves the right to assign any yacht to any division despite the foregoing and to run separate or combined starts for the divisions.
