Well, I for one appreciate the folks willing to give speed and fuel burn numbers. I gives me at least an idea what to expect from my new (to me) trawler as I learn how it performs. As one who has had planing hulls or sailboats it does me good to see how boats near mine in size/waterline perform. Personaly, I enjoy getting as much efficiency out of my cars, motorcycles and boats as I can even if they are not known to be very efficient. Getting 20+ mpg out of my 4x4 Jeep and big engine '79 TransAm is fun to me especially when I know what their performance on the other end of the spectrum is. I'm sure the same will be true for my 36' Prairie. Besides, when we take a long trip in the car or the boat, it's nice to know how far we can go on a tank of fuel. Like another has said, it can buy a nice meal at the end of the day.
