Sailboat Racing a.k.a. Blue-‐Water Chess Like a Chess Game, Fleet Racing is played on grid system where the objec

Line Bias Before the start, determine line-‐bias in order to figure out if the line is even, or if either of its ends are further upwind (Fig.5). Sail along the star
Course Geometry Determine if the weather mark is directly upwind by finding and poin
The Start The recipe for a good start is simple. Cross the star
Lay-‐Lines Start the race on
Right Wind-‐ShiD If the wind shiQs right, or the weather mark is to the right of where it should be, the starboard lay-‐line (green line) becomes longer. The basic rule is to sail the long tack first, so stay on the liQed starboard tack and sail towards the port lay-‐line. Tack before you get there.

LeD Wind-‐ShiD If the wind shiQ to the leQ, or the weather mark is to the leQ of where it should be, the port lay-‐line (red line) becomes longer. Tack to port aQer the start and sail towards the starboard lay-‐line. Always sail the liQed tack that leads closer to the next mark.

Down-‐Wind Lay-‐Lines Round the mark while easing the sails, then run down-‐wind to the next mark. When upwind lay-‐lines are equally long, the lay-‐lines down-‐wind should also be equally long. In theory, both starboard and port tack would lead to the leeward mark equally fast. Point your bow at the leeward mark. Whatever side your boom ends up, is the tack to be on.

LeD Wind-‐ShiD When the port lay-‐line is longer upwind, the starboard tack becomes favored downwind. Stay on a starboard tack to the leeward mark.

Turbulent Air Up-‐Wind Be aware of turbulent air from surrounding boats. The doJed area illustrates wind-‐shadow caused by the green boat. Red boat must either pinch i.e. sail higher, or tack. Blue boat must sail fast forward while the yellow boat must to con
Turbulent Air Down-‐Wind The green boat in causes turbulent air in front. The red boat must sail low (by-‐the-‐lee) or gybe to port in order to stay clear. The blue boat should not sail any lower and maintain the wind from leQ of the green boat.

Recognize Matching Bearings The green boat is able to sail a lower course down-‐wind than the blue boat and gains on her. This scenario assumes that the leeward mark is downwind from the course of the blue boat.

Right of way rules: Rule #10 (Fig.19) – On Opposite Tacks: Green Boat (A) on Starboard Tack has right of way over Red Boat (B) on Port Tack
Rule #11 (Fig20)– On The Same Tack, overlapped: Green Boat (C) is leeward boat and has right of way over windward Red Boat (B)

Right of way rules: Rule #12 (Fig.20) – On The Same Tack, not overlapped:
Green Boat (C) and Red Boat (B) are both Leeward boats and have Right of Way over Windward Yellow Boat (A)
