New boat owner here. Got one of these in the mail today and am totally baffled at how to fill it out. A search of the forums say you absolutely have to send it in while others say they've trashed them for 40 years. I paid around $300 taxes at the end of 2022 on a 2021 Nitro z17. They're wanting me to list fair market value. I'm a very simple man, I don't buy and sell a lot of boats or cars. Someone explain this to me like I'm 5. Can I leave it blank? Can I just pick any old number? Can I use last year's value and minus 5%? It says you need to list trolling motors too. Is all that really necessary?
