I live in Aventura Florida, 20 min north of downtown Miami.
I bought a 30ft Lippincott with an 15hp diesel engine. It was listed for 15k but I paid 9.2k out the door. it is 20 years old and needed TLC...mostly engine repair on the fuel side of things.
I believe the market for sail boats in Miami is soft and you can get a better boat for 10k if you negotiate good...I found alot of people are willing to come down thousands off the first price.
Just my opinion...!
