Provo boat harbor?

[Tin-Can]

As I just bought a new boat, I can vouch that you have to title the boat, the motor, AND the trailer, but you don't need to register or get license tags/plates for the trailer if it meets the three points R2U2 posted above. Mine didn't. (Due to staff shortages at DMV from the Covidiocy, I still don't have hull numbers, though.)

    OK, I checked back thru all my boat and trailer documents. I do have a registration / title on the trailer but because the boat isn't 18 ft. and the trailer is single axle, and it only weighs 375 lbs.  I do not require a plate or annual registration renewal on the trailer.  
My new motor also has a registration number provided by the dealer (Fred's Marine) as well as a title, but no kind of sticker required. So all I am required each year is  the renewal of the boat registration at about $53.00 a year. 

But in my research yesterday, I did learn that the DMV is no longer sending out post card renewal reminders. You can, however, request an email renewal reminder on the DMV web site. Be prepared to provide the last 4 of the VIN / HIN,  Hull number,  or plate number,  of any boat, vehicle, trailer, RV or whatever else you would normally renew registration on each year.
