Just got off the phone with Cabelas as they sell the roughneck with a galvanized trailer for 7,500 dollars. The boat is a tiller 20 foot by 70 inch wide floor and beam to beam it is 85 inches. The thickness is weak at .1 and 5052 aluminum. BUT that is a cheap boat...
ATEC boat .125 thick 5052 aluminum, 72 inch bottom, 24 inch sides, 20 foot long about 9,000 dollars.
I am going to stop in at Wooldridge on the way home.
