It seems like there are tons of boats from $1,000 to $2,000 with the $1k boats being "4's" and anything less than $1k is trashed. Needs to be an "8" or better to get more than $2k for it.
Add a bit for "BIG" names--AIRE, Sotar, Maravia, Hyside, NRS, especially if they had warranty remaining (private sellers); less for Aire's Trib and NRS' Otter series.
I was shopping last summer and that seemed to be my experience.
I had a 16' Maravia that was 8-9 years old and probably a "6" when I bought it for $1,100. It was probably a 4-5 when I sold it for $900 eight years later. It sold three hours after I listed it on Craigslist (May of '12), so I probably listed it too cheaply! I listed it for $1,000 and let the seller talk me down to $900 and I threw in my old conduit frame that I had $60 in materials.
Maybe ask $2,500 or $2,600 for yours, if it doesn't move after a couple of weeks, drop it to $2,300. It's only the end of February, after all. If you start at $2,500, you'll also have room to move down to $2,300 if the seller wants to haggle.
