We are selling a boat as well and were contacted by these people. What happens is that she will say that she has transferred the money to your paypal account and adds the shipping on to it as she says paypal instructs her to do that. She then expects you to pay the shipper in maylasia and then paypal will release the funds to your account. You will even get an email from paypal(fake) I contacted the real paypal and they confirmed it is a scam and that if someone pays you it will how up on your paypal account right away!!!
