As you can see I have added a second roller furling system as an inner sail.

The main (forward) furling system is a ProFurl, with a new 145% Tri-Radial Hi-Tech North Sail (Made in New Zealand)

The inner system is actually the original Mariner furling system with the 110% (re-cut) hank-on sail I had made but never worked.  It is now a 100% which will reef down to about 70%, made or heavy (8.5oz) Dacron.

This view shows the new deck fitting I had installed to support the inner stay. It is backed with 3/4" marine play which covers the entire under deck space, and sealed in.
