If you receive this form 1099-NEC for a personal boat for less than you paid for it, you have made a loss on personal items. This loss on personal items is not deductible and is not reported on your tax return.
If this is the case, you do not need to report this form 1099-NEC on your tax return. Just keep it in your tax records along with any proof that it was for the sale of your boat.
