RIB wanted

"We are looking for a 17-18ft RIB, probably 50HP or more. We would like aluminum body, but it isn't something concrete. A trailer with it would be awesome, but not required. Trying to keep is around $16-18k."

My goddaughter and her sailing partner (Arielle and David, Hein-Darrow Sailing) are looking for a RIB as a chase and coaching boat for their 2020 Olympic effort. They sail a Nacra 17 catamaran, kept in FL. Having their own chase and coaching boat would reduce the cost of hiring coaches.

If anyone has something of this kind, please let me know, or if you know of anything. I am also looking, but I don't know much about RIBs, so I am also trying to get an education on them.

Thanks, in advance, for any help.
