3 elements of racing - Boat Speed, Strategy, Tactics,
Boat Speed – Getting the most out of what you’ve got
Strategy – Making the right decisions and going the right way
Tactics – Keeping others from interfering and making them go the wrong way
NOT Rules
Conflict is manageable
Confrontation is distracting and slow
Collision is bad for everyone
Boat Speed – Tuning the engine
Bernoulli’s principle
Sail shape – depth, position, angle of attack & twist (Wind sheer)
Main, Jib & Interaction
Boat Speed – Shifting gears; where, when & how
Light - Generating boat speed (footing)
Medium - It’s already there (Footing or pointing)
Heavy - More than you need (De-powering)
Rigs & keels – Aspect ratio
Preparation – tell tales, draft stripes
Hoisting – wrinkles
Jib twist
Main matching the jib - trimming the leeches
Shifting gears – Panel
Break
Strategy - Making the right decisions, going the right way
Wind – Understanding it is the key - Veering / Backing
Persistent / Oscillating Shifts
System features – Highs, Lows, Fronts
Sea breeze
“Drainage”
Shoreline
Shore turns
Hills & valleys
Lifts / Headers
Recognizing them (Compass, shore sights, boats)
Dealing with them
Course diamond
Tacking – 5/10 boat lengths
Corner effect
Oscillations
