You must have some ties to CYOA. I have chartered from numerous different charer companies around the world. CYOA is by far the worst charter company to deal with. I rented two boats. A 38 ft lavezzi and a 40 ft leopard. The boats were filthy, had mechanical problems on the second day, they were no help. I had to jury rig it myself and limp along for the rest of the trip. They offered no credit, no refund, not even an apology. My suggestion, as recommended by the owner, read the fine print in the contract. It basically states that they can stick it to you, but you can't sue them if they are liable.

Read trip advisor, it's loaded with bad comments about them.
I would not recommend using a boat from them.
