We bought our last three boats online, two Craigslist and one eBay, although the seller also listed it with Pop Yachts at the same time. All went well, but maybe we were lucky. When it comes to annoying, there is a lot of junk and spam out there with boat listings. In fact our current boat is still listed on a junk boat sales website, a site that lifts real listings and re-posts them. Our boat hasn't been for sale since we bought it in 2015. And then there was that time I drove three hours to Titusville, Florida to look at a boat. Online the hull was mirror-polished, pristine. When I got there there were birds' nests on the helm dashboard through the broken windows. It's the 'net, comes with the territory I suppose.
