Sounds the same I think mine is royalex but not sure bought it second hand like all my boats.

We just redid the seat in my buddies Bell Wildfire.

Pretty easy to hang a seat from the gunnels. We used 4 inch or maybe 5 inch SS bolts and for spacers I have some carbon fiber tubing we cut. Very stable. My pack is basically the same, seat hung from the gunnels.

Pretty small boat length wise for two paddlers but it sounds like you have it working for you.

My Pack
