Carrying thwarts are 2"x2" pine stock with 1/4" bolts. Center yoke/thwart is also unlike the other two and has a huge knot in it and looks home made. the decks measure down the centerline 16 1/2" or 17" and along the side 17 1/2" or 18" DPENDING on how I measure it. And they are steam bent. Planking is 3 3/4". Inwales look like mahog. No sign of any numbers, so they were either sanded off or there is too much varnish for me to tell at this point. I was searching the site and did not find much. I leaks slightly, has been glassed and therefore weighs 4 ounces less than a battleship, but it paddles wonderfully. Stiffens up when heeled. I think even I could sip water over the rail with a little practise.
