I Have a 1971 Thunderbird Sawnee 17 ft trihull boat. I need to find the hull number. I found a set of numbers that I believe is the hull number but are not engraved into the boat. I found it printed on a metal tag on the stern of the boat. NJZ-#####-hull. Does this look like a hull number. It looks like it was added on. The reason I ask is that there is no title on the boat and I can't find the last owner that had it registered. How hard is it to get a title in NJ. They told me to send a letter to the the Dmv with the boat information and in a month they would let me know how to obtain a title. Talk about leaving you hanging.<br /><br />Thanks<br />Warren
