Do not take money through PayPal. While it is good for the buyer, it can be bad for the seller. One of PayPal's guaranties is that they will refund the buyer's money if there is a problem with the transaction. If the buyer claims that the item purchased did not agree with item description (for example had a paint scratch that was not described) PayPal will refund the purchase price to the buyer. Since PayPal has a link to the seller's bank account (to deposit the buyer's money), they can get your money without your direct approval. It is possible for the buyer to end up with the item you sold AND get his money back. Good luck trying to recover your item from another state if the buyer pulls the scam on you. This is a common scam. I sold my previous boat via CL and got approached with this scam by most of the "interested parties".
If you are going to sell your boat. Meet the buyer in person, accept only cash (get one of those counterfit detection pens for checking the cash), and provide a bill of sale that is signed and retained by both parties. Do not sell to someone's "agent" unless they are a licensed broker (another related scam).
My boat eventually sold to a guy that drove 900 miles to get it. If the purchaser is legit and really interested in your boat they will find a way to come and get it.
For a high dollar boat, enlist a broker if you cannot do things yourself with the buyer. The broker is on the hook for the transaction and sorting things out if things go wrong.
