Too little info. No descriptions. Is the motor paid off? Any updates, new carpet, electronics, TM? The question should be “What do YOU value your boat?”
Best thing to do is go over to NADA.com to figure your “used boat” value. Then take into consideration what area of the country you’re in as to whether the value is too high or accurate for the location.
Remember the issue will be finding the right buyer as you won’t likely get what you think it’s worth.
Knowing this, I would think $12-13k would be ballpark if all else being equal, the boat being in average condition.
I had listed our boat about 2 years ago and had pictures also. Carpet was ragged and I explained that the price was adjusted to offset the cost of new carpet. Then when we had new padded carpet done to the boat people were still looking for that deal. But then I felt it would be irresponsible to sell knowing that the trailer we special ordered was a lemon, so I stopped trying to sell.
Now that we paid to get it corrected, if we sell it’s still going to be less than what I put into it. That’s the caveat of updating an older boat
