I've been a buyer but never a seller. My First Mate and I were *amazed* at the god-awful pictures some people used to try to sell their boats. Descriptions of any given model were all pretty similar and didn't do a whole lot to sell us. In the end, it was the pictures that sold us on looking at boats.
Look at the pictures you take and ask yourself if you would buy that boat. Better yet, have a friend, or even better yet, have your mother look at the pictures and tell you honestly what they think of them. Make your buyer fall in love with your boat for the same reasons you did.
Realistic pricing is very important. We found a boat we really liked but the seller was asking about double what is was worth. Turned out he wouldn't budge on the price because he needed the money to buy a bigger boat. We decided we didn't want to buy the bigger boat for him.
When a potential buyer comes to see the boat make daggum sure it is in pristine condition. We almost walked away from the boat we ended up buying even before the owner arrived. The hull was so covered with barnacles it nearly made us cry. We did end up buying the boat but insisted the owner have the hull scraped and painted at his expense.
Basically I'm agreeing with everything SeaMist said and elaborating on some of his points. It also wouldn't hurt to have a friend, or better yet your mother, walk through your boat and point out things you've missed. I promise you can't see everything yourself. The buyer will.
Good luck!
