Do boats need a title in Wisconsin?

Which boats need a title

Wis. Stat. 30.531 says the owner of a boat subject to registration must apply for a title when they acquire it. The same section exempts boats under 16 feet, boats that are only voluntarily registered, boats bought here by nonresidents who will title them in another state, and boats that are exempt from registration in the first place.

That last group matters more than people expect. Under 30.51, a non-motorized boat that is not a sailboat does not have to be registered, and neither does a sailboat 12 feet or shorter or a sailboard. If it does not need registration, it does not need a title.

• 18-foot fishing boat with an outboard: registration and title.
• 14-foot boat with a motor: registration, no title.
• 17-foot canoe, paddle only: no registration, no title.
• Put a motor on that canoe and it becomes a motorized boat, so registration applies, and at 16 feet or more the title rule does too.

Buying a used titled boat

The DNR's own buyer checklist says not to pay for a titled boat unless the seller has the original title (not a photocopy) signed by every required owner. If the owners are joined by "and", all of them sign. If they are joined by "or", any one of them can.

Look at the back before money changes hands. The seller fills in the assignment with your name, address and the price. If that section was already filled in for someone else, or has changes or cross-outs, the DNR says the seller has to get a replacement title first.

If a loan shows on the title, get a lien release from the lender. The DNR wants it to name the lienholder, the owner on the account, and the boat by hull ID or registration number, signed and dated by the lender.

Where boat buyers get stuck

Most delays on boat transfers come from a handful of the same mistakes:

• Starting the transfer on GoWILD and stopping there. For a titled boat, the signed original title, lien release and other papers still have to be mailed to the DNR, and the transaction stays incomplete until they arrive.
• Writing a low price. The DNR notes that the Department of Revenue checks applications and looks into suspiciously low sale prices.
• Waiting. Under 30.549 you have 10 days from the purchase to apply for the new registration, and you must apply before you use the boat.
• A missing hull number. If the manufacturer's hull ID is gone or altered, the application has to say so, and the DNR assigns a number that goes on the right (starboard) side of the transom.

If the seller has no boat title

Section 30.549 puts this on the seller: an owner who does not have the current title must give the DNR whatever documents or information it decides it needs to make the transfer. The DNR can also ask the buyer for further evidence of ownership before it issues a title.

The DNR does not publish a bonded-title process for boats the way WisDOT does for cars. Call the DNR at 1-888-936-7463 (7 a.m. to 10 p.m.) before you pay, and ask what it will accept in your case. WisDOT's bonded title form, MV2082, is for vehicles WisDOT titles, and boats are not among them.

The boat trailer goes to WisDOT

WisDOT's trailer chart says a boat trailer over 3,000 pounds needs a title and plates, and so does a trailer of any weight used for hire or rental. A lighter trailer that is not for hire does not, though WisDOT recommends title and plates if you will use it out of state.

If you bought a heavy trailer with the boat and the trailer has no title, that part is a WisDOT question and can go through the bonded title process. Our $97 kit covers that process step by step. The boat itself stays with the DNR.
