Here is my 1970 Thunderhawk 1400 boat which I used at Grand Lake, an 8 mile long, 5,660 acre lake in Presque Isle County 20 miles north of Alpena, Michigan. This cathedral tri-hull boat is 13 feet 3 inches long and weighs about 525 pounds excluding the motor. Beam is 63 inches and transom height is 18-3/4 inches. I bought the boat new, picked it up at the factory which from their mailing address I thought to be in Dawson, Georgia. Asking around in Dawson to find the factory, a local resident directed me to another town some distance from Dawson. I do not remember the name of the town but it may have been Rebecca. The trailer, which traveled behind me from Ohio to Georgia and back, is a Little Dude model 948 modified by adding an extra leaf in the springs, a 61.5 inch track width, 1-1/4 inch square, solid steel axle, electric brakes, and a few other enhancements. Originally weighing 240 pounds it is probably now close to 300 pounds. The trailer dolly is homemade. When viewing in the slideshow mode press the [Tab] key to toggle this text window On/Off.
