Sail Trim Class

It’s always fun, and a sign that spring will eventually arrive, to share sail-trim concepts with the hopeful and studious folks at the Milwaukee Community Sailing Center. Here are the presentations from this year’s classes. Download and share as you wish.

Upwind Sail Trim; Mains, Jibs and Rigs

Downwind Sail Trim: Spinnakers, Speed and Polar Diagrams

And here’s the cool Wind Tunnel App that makes classroom conversation a tad more tolerable.

Let’s do this on the water when the ice breaks.

Spinnakers and Speed

Spinnakers on Milwaukee Bay

Another great group at last Thursdays’s MCSC Advanced Sailtrim Theory class. Nothing like a polar diagram to show why downwind sailing should really be called downwind flying if it’s done right.

We discovered that the iPad Wind Tunnel app is just as good a tool to explain downwind sailing as upwind sailing, and more importantly, why “dead down” is appropriately called “dead down” (lot’s of drag, not much lift.)

Thanks to all who attended this series of classes. There are still a few great ones left at MCSC. Register here.

If you’re looking for the slides, missed the class, or would like to use these ideas for your own class, feel free to download┬áthe pdfs, and use the message tool below for feedback – questions, corrections and ideas. All welcome.
