Hi Bellman, I knew the real Venta way back, soon after she was converted to a barge yacht. She was moored in Whitewall creek near my home at Lower Upnor on the Medway in the late forties.
Have you scratch built her or did you start with a hull?
Best of luck with her sail plan, if I can give you any further help, please ask.
All the best, Nerys.
