Go/No-Go

                                                                                                                                                 by Cathy

Yesterday it was cold, windy, and cloudy.  A few of us met, had some hot chocolate (thank you, Bowman), then headed to Green Spot for tacos.  No sailing, but fun to see friends.

While wondering about sailing yesterday, I remembered seeing a Go/No-Go chart at CSC, so searched on the internet and found a chart and interactive calculator.  Since these are handy to help us determine when sailing is safe this winter, I have saved them here.  There are also some links on the bottom right side of the website about cold water survival.

And here is a chart I found which comes very close to matching the calculator.
