I was able to get new watercraft registrations through the Scott County Gov’t center using their drop box outside. I did this for a new (used) boat, which took a few visits and back and forth, to get the correct paperwork to fill out, but it was completed. I also got new registration for a paddleboard, which is ridiculous, but required.
What I could not get done, was license for the trailer, as that is DMV, not DNR, and they have haulted service. So I have to wait for that.
By the way, if you use the drop box, use a water proof envelope, it fills with water and completely ruined my documentation, including the bill of sale I had.
