The invasive species permit is new in Oregon. If you have a motorized boat here, of any size or shape, gas or electric, you must license your boat, and that license carries with it the extra fee for the permit and only that license decal is required as proof. What I don't know is the rule for boats that were licensed last year. If your boat was licensed this year, you're covered. But if your boat was licensed last year, do you have to go get a permit to get you through until you renew your boat license? We live in a wacky state with a wacky government so it wouldn't surprise me whatever the rule on that is. If any of you know the answer to this though I would like to know.
