The mainsail is pretty small compared to the jib so it is easy to remove by only one person.
The inmast furling system is identical on most Bavaria boats and I give a explanation about how the system works, some stuff is nice to know when you furl in and out, a lot of people has problems with the sail is jamming inside the mast or in the top.
My mainsail is the version without batterns but you can also get many other versions with batterns, something which can get stuck pretty bad.
The best is to remove the sail in almost no wind.
