I don't like the yards attached/mast rotate method. Standing rigging must be heavily modified to accommodate the rotating mast. Plus, it's not at all realistic, if that is an interest of yours.
It's relatively easy to RC a kit using dowels for masts and yards, and simple screweyes for the yard hangers. The yards are then swung with braces, either using standard aircraft servos (the Parallelogram method), or with winches. Winches are more complicated and expensive, but provide realistic running rigging. The simpler parallelogram method uses cheaper servos, and is easy to debug, at the expense of some realism. At 50' offshore, both methods look about the same.
