Nice link, might have to try the thicker replacement pads. The old school 4" foam pads are not bad either.

Mad Mat,

What I noticed on my royalex solo boat is that it has a tendency to flex when I pick it up, have to be careful to not let the boat get any wider in the process... or the yoke may work itself loose.

The only thing I can think of is to add another thwart behind the seat or place longer thwarts closer to the seat. Or perhaps change how the yoke is mounted so that it also grabs the outside of the gunwhale?

Didn't notice the boat flexing length-wise (14'), but I wouldn't doubt it. The flex in the boat width is hard to miss.
