Riveted aluminum, used frequently for past 4 years, weighs about 175lbs, registered trailer, rated for 7.5hp, I ran a Johnson 9.9. Flat bottom, super stable, took the kids/friends fishing frequently in and around maple bay to Cowichan bay. Upgraded to bigger and better, $350 boat, $250 trailer, sold as a package only. Trailer not pretty but perfectly functional, newer tires, good bearings, could use a couple new tail lights ($8 each). Dave.
