I was very interested in one particular C-Dory that was listed by POP Yachts when I was seriously boat shopping. The only option I could find to get more information or get in contact with anyone was to "sign up for" it. Um, no thanks, I'm the one about to spend my money. Why should I sign up with POP Yachts when I can see photos and ads here, on Craigslist, on Yachtworld, etc. easily and freely. Usually a company is trying to make it easier for a buyer, not harder. I never did get to see that boat, and I almost wished I could contact the owners to say "Did you know that I would love to have looked at and likely bought your boat, but your selling agent made it too much of a pain?"
A friend had a similar experience, and a similar reaction when he saw a boat he was very interested in that was listed by POP.
