Basic 'brochure data' for the R23, shows considerable mast rake and with the combined CE of the sail plan 'in front' of the mast. RANGER 23 sailboat specifications and details on sailboatdata.com
Most other Ranger boats Ive sailed seem to have quite neutral helm balance, so mast rake is going be important because of the CE being forward (slightly) of the mast.
Also if you single hand a lot you probably wont have a lot of body weight aft ... also affecting the amount of mast rake as a heavier crew weight will help with the relative amount of rake.
The R23 had a large race/class following: Ranger 23 Owners & Class Association. So a websearch for the R23 class info, etc. might still be available. If you cant find much on the internet, also search the ArvelGentry.com
website specifically looking for the Ranger 23 class info and boat 'set-ups', etc.
