If the boat is heeling over and main is washing out, the first thing to do is roll the jib down, but smart seamanship requires looking at the conditions ahead and setting up the boat early before you get overpowered. You’ll see the water start to whitecap consitantly between 11-16 knots. If you see whitecaps ahead, you should be thinking about a reef in the main. Look to where you want to go—if the boats already there are well heeled over, put in a reef. Depending on where you live, other telltale signs may include kite surfers ripping across the waves, a low fog blowing in, or racing boats crashing and burning—you don’t want that to be you!
