Thoughts -Facnor mast furling on Beneteau

[Quietta]

I am in the market for a used production boat and one of the things that interests me is in mast furling. I am not here to discuss the pros and cons of in mast furling, suffice to say that I specifically chartered a boat with in mast furling to try it out and it suits my needs.

One of the boats I am looking at is a 2007 Beneteau 40, the add says it has a Facnor system installed. Looking at the Facnor site and watching the youtube video, it appears that this system is retrofitted to a standard mast. I have to travel a long way to see this boat, the photos on the add don't provide enough detail.

People with this system fitted from the factory, is it an external system that fits to the mast track? What are you experiences with the main sail furling system offered by Beneteau?
