My Caracal fully loaded (225 SHO, 54 gals gas, all electronics, fishing, and safety gear) on trailer is pretty close to 4K. Probably pretty close in weight as an Eyra is a bit longer but narrower, I think listed as slightly lighter hull (but within 50# of the Caracal at 1725#?). If the Ridgeline is 4K towing capacity, that’s closer than I would be comfortable with. I tow mine with a ’20 Toyota Tacoma w 4WD, 6K towing capacity. Works just fine. Anyway, my experience – certainly not the only answer.
