The key to buying
or selling a boat is to not be in a hurry and not be emotional about the deal.
I sold my last boat for 90% in a little less than six months. She was a great boat in beautiful shape. I still miss her.
I would always respond to low ball (from my perspective) offers with a "Thank you" but no counter. I don't particularly enjoy negotiating. And I was in no hurry to sell as I had low carrying costs.
If it hadn't sold in 12 months, I would have dropped the price
When I buy a boat, I look for the best quality, best maintenance
, and a PO that loves his boat. This always costs more and I'm glad to pay it.
I realize this isn't typical, but it works for me.
