Trim for Waves

Check the seminar registration site for details. In anticipation, Bill Gladstone of North U. has provided US SAILING members with another racing tip this week.
Trim for Waves
Each sail has three sources of power: Angle of attack, depth, and twist.
Proper trim means sailing at full power and with the proper mix of power. For a given wind speed, a deeper more twisted sail shape is preferred in big waves or chop. A flatter, less twisted shape is better in smooth water. Same total power, but a different mix. The deeper, more twisted shape provides better acceleration, a wider steering groove, and more consistent power as your boat pitches and is slowed in waves. The flatter, less twisted shape provides better pointing and less drag for smooth water sailing.
North U. has partnered with US SAILING to provide our members with a couple great discounts.
