In the 1970s and 1980s, I spent time talking with other captains about how big boats could get. Back then, a 40- to 50-foot boat was big, and when Hatteras came out with a 60-footer, it was almost unimaginable. At that time, the engines did not have enough horsepower to go much over 20 knots. But the biggest problem lay in maneuverability, which is more important than speed when it comes to chasing down fish. A 90-footer will never be as nimble as a 40-foot boat, but thanks to today’s horsepower, the big boats can spin around and back down 10 times better than the 50- and 60-foot boats of the past.
