stem

The arc on the bottom does cut out the rocker,but at what degree. The width affects the rocker too. But we'll stick to one thing at a time. You need to know about how much weight you will carry most of the time and ajust this 2" or 1 /2" for the arc. what you want is the bow just out of the water. If is to high, it will catch air and you will wander back and forth. If in the water than you will be pushing water the whole time. this is another notch up,good luck, keith

Chuck, you have built more than one of these (how many is that?), does the rocker feel 'right' on the UJ?

Not that many just 5 so far. The rocker on them is from 2 inches to 2 1/2 inches. The angle on the outside of the ribs controll most of the rocker.

angle

Hi Chuck, what angle do you use on your sides @ midship beam and how wide is the bottom? Thanks, keith

I wish I could help on the angles but I have no idea , I get the kit from John and all of the necessary parts are already cut to shape.

The beam is 30 1/2 at the top and 25 1/2 at the bottom

OK... found it!

Here's the link to some free plans:

I think the stems are exactly what you were describing.

Interesting plans but I think by in-curving the bottom edge of the side boards it would reduce/remove the rocker that you would get with the UJ plans.

The link above is no longer valid. https://www.lsuagcenter.com/~/media/system/3/1/4/f/314fa826354f6585a2d07063ed8aa2ca/2801pirogue.pdf is correct as of today.
