I have the same model and a similar backstory. You have to get used to the heel and the "give" of the hull, but it's more stable than it looks.
You may find its value is as a cargo carrier; if you throw in a few five-gallon diesel
jerrycans either side of the centerline (and maybe fore and aft of the first seat), it rows or motors very well.
I received a notched length of 1/2 x 4" lumber
with my used Portabote, which holds the hull open until you can get a seat notched in. Helpful and a time saver.
Another idea I've seen are two lines to through-bolted eyelets just under the gunwhales. You need backing plates
and perhaps bushings to spread the load. Hooked to the toerail, the boat is kept level (or more level) for boarding and loading/offloading.
Another idea is to fab up a pool noodle to go over the gunwhales either on lengths of line lashed to eyelets. It means you can run into things without dinging them, a friendly modfication if you have a "neutral-less" Honda
Lastly, it is possible and desirable to replace the black plastic seats with white-covered (fabric or rubber sheet) planks. The benefit is that these seats are perhaps 1/2 inch thick and take up much less room and are cooler (but not lighter) than the "stock" black plastic seats. Also, then can take screws/bolts, if you want to sling emergency gear
or extra line beneath them.
Hope this helps. They are cool little boats, and are near indestructible.
