Rule of the Month: Windward-Leeward

Greetings sailors! During our April 10 practice racing we’ll concentrate on the basic windward-leeward rule: When boats are on the same tack and overlapped, a windward boat shall keep clear of a leeward boat.

Here’s a diagram that explains the terms:

When a boat is sailing by the lee, the leeward side is the side the mainsail is on. (B is sailing by the lee by heading more than 180 degrees from the wind.)

To define overlap, the RRS start with clear astern and clear ahead:

Two boats are overlapped when neither is clear astern:

Also, they are overlapped when a boat between them overlaps both. In this case both A and B must keep clear of C.

Here’s a test. Are these boats overlapped? If so, which boat has to keep clear?

They are on the same tack and overlapped, because neither is clear astern. A is on B’s windward side, so A has to keep clear.

But wait, there’s still more to learn about establishing or breaking an overlap, and limitations on the leeward boat’s actions. Stay tuned!

Please respond to me with comments, questions, or suggestions. -Stan McKay

Frostbite #2 (3-21-21)

More wows we had approx. 18 boats in attendance 9 DF65’s, 7 T37’s and 2 DF95’s. Also despite early weather reports the rain held off till after we were done, with decent wind. Lynn Moore had to retire early w/sail winch problems. We had several new members and several future members. Jim Hansen brought his beautiful brand new T37 for it’s first outing and did a couple races with us and indicated his intention to join, he also brought a grandson and his father who Peter set up with his laser for some off course fun. Need to get the little ones started early. Other new people Sherrell Steinhauer with his Df65, Nelson and Chris with their DF95’s sailed just ahead of the T37’s on a 30seconds and away format which worked most of the time so next time we’ll do a full one minute gap. Also The Super bee T37 has a new owner Paul Wallace who did pretty well with a boat new to him. No one Skipper dominated any class  so the wins were pretty well distributed across the field. Tom Box also made an appearance nice to have him back always a strong competitor and sailed both DF65 and T37, makes a busy day. Peter also brought the club T37 which helped Art out because his transmitter didn’t make it to the pond with his boat.

POOPOO occurs.   Hope to see everyone at the next event on April 10th for a fun sail lets get all the bugs out so we have smooth sailing later.  Race results posted.  Gary

Funsail 3/8/2021

WOW wow wow we had a great turnout yesterday and no more than a light sprinkle.  I counted 17 boats on the water at one time which I believe is a new record. We had all kinds of boats from Micro Magic’s to a 10 Rater and Marblehead 50 and everything in between. Two DF 95’s lots of Dragons a few t37s Victorias. I am sure I am missing something no malice intended. Also we had mostly decent winds but incredibly shifty. Everyone wore their masks and social distancing was practiced.  Not everyone can make every event but days like yesterday make me feel bad for those that didn’t attend, Next event is a frost bite series race on Sunday March 21st at noon at Tualatin Commons mark that on your calendars and do your best to attend. See you on the 21st – Gary

Saturday RC fun sail (March 6 2021)

Greetings sailors!
RCMSC will hold a fun sail at Tualatin Commons on Saturday, Mar 6, beginning at noon. The forecast: cloudy with scattered showers, low 40’s, and wind 7 mph with gusts. Bring all of your boats for casual sailing. Masks and safe distancing are still advised.

During practice racing we’ll concentrate on the port and starboard tack rule. Remember, a boat is on the tack corresponding to her windward side. When boats are on opposite tacks, a port-tack boat shall keep clear of a starboard-tack boat. Below are situations showing boats on opposite tacks. In each situation, decide which boat must take action to keep clear and avoid contact.

Answers: 1)A, 2)A, 3)B, 4)A, 5)A and B, 6)B

Situation 6 might be confused with a boat clear astern having to keep clear of a boat clear ahead, but that applies to boats on the same tack. Diagram 6 shows boats on opposite tacks, so B must keep clear. – Stan

Frostbite #1

I was kinda dreading sailing in the cold and rain today but the rain never appeared in anything more than a mist. But we really had our share of wind. Not everyone can make every event but today is the type of day that goes to show it is better to come and take a chance than to skip it do to the forecast. The strong winds really tested our boats I had water in my boat despite my brand new hatch, Ed lost his hatch tried to race anyway and almost lost his boat. The spare boat I loaned him developed a rigging problem purely related to the additional strain of the strong winds. Peter had a weakness in his rigging revealed that was just bedeviling him and Rick had a sail winch pretty much give up the ghost. racing was keen no one skipper dominated, all had good and bad races. All in all a great day playing at the pond. Also two or three new people showed a lot of interest in the activities and we will be seeing some of them at our next fun sail. In closing I have attached the Frost bite schedule I believe it will print. We had 14 today lets shoot for everyone on march 6th noon at Tualatin. stay well Gary

Rules We Sail By: Port/Starboard rule

Here’s the basic port/starboard rule from the 2021 Racing Rules of Sailing (RRS):

When boats are on opposite tacks, a port-tack boat shall keep clear of a starboard-tack boat.

Two definitions in the RRS tell you how to know which tack you are on.

Tack, Starboard or Port A boat is on the tack, starboard or port, corresponding to her windward side.

That’s easy, but how about when you are running downwind?

Leeward and Windward A boat’s leeward side is the side that is or, when she is head to wind, was away from the wind. However, when sailing by the lee or directly downwind, her leeward side is the side on which her mainsail lies. The other side is her windward side….

All of the boats drawn below are on starboard tack. The arrow indicates the wind.

Before the next race while you are sailing your boat near the starting line, think about which tack you are on both coming toward you and sailing away. I’ll show typical port-starboard situations in a couple of weeks.

Richard adds: A definition of port/starboard that I’ve seen is port is when the mainsail is on the starboard side and starboard is when the mainsail is on the port side. This covers both up and downwind (wing and wing).
