Hon är nu en del förstorad och slagkraftigare för att möta hotet från den slagkryssarhausse som drabbat världen. Hos Shipbucket har det med tiden verkat fram tre förslag som jag kommer presentera här. De är mest ute efter snygga båtar men jag tar gärna en diskussion om det tekniska också, vad säger ni?
