To transfer a Florida title of a used boat to the new owner, the Transfer of Seller section on the title must be completed. If the vessel is purchased through a dealer, the dealer reassignment also must be completed. Sales tax will be collected if applicable. In the event the title is lost, a duplicate title may be applied for using form HSMV 82101. When the vessel owner is not present, the owner can sign a Power of Attorney, form HSMV 82053, to allow the purchaser or agent to act on his behalf.
