Hey there, I don't have that exact setup on a Hanse 371, but I've been running a North Sails Easy Furling gennaker with a different model on my boat for a couple of seasons now.
The key for me was getting the halyard tension just right.
If it's too loose, it's a mess. If too tight then it's hard to unfurl.
Also, make sure your tack line allows for a bit of play, or the furling can be a real struggle, especially if there's any wind.
I found that leading the furling line back to the cockpit through a dedicated fairlead made a huge difference for solo handling.
It's a great sail once you dial it in!
