What do you do, or how do you handle a very large ships wake? When traveling through the shipping channels do you run across this and what would the advise be if you did? Some of the swells from those ships are pretty big.
Always try to stay at a minimum of 45 degrees to any wake. Though 90 is much preferrable. Definetly slow to a speed where you can safely cross them. What that speed is depends on your boat, the size of the wake you approaching and the general swell direction.
