In that circumstance, a better course of action might be to get closer, cautiously. That white band is big breakers, and as you get closer, you’ll be able to see how far out they begin. They may simply be across the mouth of the pass. Then again, there may be three, four, or six or more rows of breakers extending well offshore. These lines of standing, breaking waves may be close on top of each other, just boat lengths apart — or they may be spread out. You won’t know until you get closer in, just outside of them if possible, and slow down or stop to assess the situation. Like a surfer, watch the waves and see if they aren’t coming in sets of five or seven. (These aren’t fixed intervals, though experience teaches they are good starting points when looking for a pattern). Often, with some time spent observing, you can determine which wave in a set averages out to be the smallest and make your crossing during that wave. In any event, stopping to observe will let you plan your transit, knowing in advance where you’ll need to accelerate, where you’ll need to slow down, and where the waves are coming in just a little from one side. This is a good time to break out those binoculars your wife gave you for your birthday a few years ago, if you have them.
