The thing to remember is any boat on the water is vulnerable to human intellect. Best thing to do in any boat is study the weather and make sure the boat is ship shape and water tight. That being said, I've been caught at an island 40 miles offshore, cold and tired from sitting on anchor overnight in the wind. We decided to make the crossing at first light but should have waited. We surfed down swell 10+ footers for a few hours making about 10 miles before things calmed down. This was in an 18 Parker with "interesting" occasional bow steer characteristics. If the motor had quit, we would have been swamped for sure. Would much rather had the 20 Seacraft! Yep, vulnerable to human intellect.
