In-mast roller furling
Robert; I have the in-mast furling on my Bene 40. It's a good system, but it takes some tweaking and a little experience to avoid some common pitfalls. You need a larger headsail, say at least a 135, to compensate for the roller furling main's loss of power. When setting and rolling it up, put the wind a little to starboard, and easing the vang will make it roll up easier. Control both lines in/out to avoid a wrinkle in the sail that will jam in the slot. Enjoy!
