Interesting thread. In Oregon a boat must be registered. Even our old decrepit Sunfish has numbers. I do not know what the minimum length is for registration. I have been stopped on a lake twice in the last 10 years while sailing. Once on my P-16 and once on my P-15. Both times I had a temporary renewal while waiting for my new stickers. I carry my registration in a waterproof plastic container, about the size of a 35mm film canister. I almost got dinged many years ago with the Sunfish sitting on the beach with out of date stickers.

Fortunately the previous Prindle owner had the title when I purchased it. I have seen people without titles try to register a car or trailer, and it was a real hastle. I assume doing a boat would be just as bad.
