Start-up instructions for a Ferret are less complex than a 432, Stalwart or Saladin, and we have had all moved via RORO using such. These people move all kinds of equipment everyday. They know what they are doing. But I would never move anything without a CONEX unless I had to. A Ferret in a CONEX is not that much more money and you can stuff it with spares and accessories; easily enough to sell extras and pay for the entire shipment. Extra engines, gearboxes, periscopes, CES, Sand Channels, etc always bring good money on Ferrets. On a RORO, you always run the risk of shipping damage and/or pilfering.
