I'd double-check this, I was told that you don't need the number, as you stated, but in addition to paying the tax you need the sticker every two years.
From the DNR website (link above): "$24 REGISTRATION FEE
Vessels 16 feet in length or less and/or propelled by a motor of 7.5 hp or less must display a 2-year registration decal but are exempt from the fee.
The 2-year registration decal is valid for the calendar year in which it is issued and the subsequent year, expiring on December 31.
$10 DOCUMENTED DECAL (required of USCG documented vessels in lieu of the registration fee)
