Well...I have been planning this build for over a year.  Unlike my practice..I will not be  modifying a Revell CS hull....but will be building a scratch POB model of the Great Republic from a couple of sources.  Namely the McCann plan and those supplemented by the plans provided by Arthur H Clark, and drawings from Crothers, manuscripts and first hand wood etchings of the vessel.   Unlike many contemporary replications...I will be following the descriptions of her rig by Duncan McLean
