Safety is my first priority, and as I will be alone doing night sailing, I think it is a must to prepare the boat with a jackline, to prevent to fall over board.
We already have on Mamma Mia the jack-line connectors, that I will attach to my personal auto-inflatable life vest 150N, what is missing on Mamma mia are the jackline itself. Many websites suggest how to install them, and I will follow the suggestions to mount them as close to the centerline as possible (the aim is not to stay attached to the boat when overboard, but not to fall!).
For the dimension: Most site recommend a load of 1.5-2tons for the jackline, it seems a lot but it is reasonable if you think it should sustain more than one people during a potential fall, so the dynamic factor has to be considered. So I got a 9mm Polyester rope with 3.5tons load and some spectra that I will use to fix the jackline on multiple points, using the beautiful prusik knot.
In addition I also got some elastics lines, that will be very helpful to keep the sail down in case I will have to switch from Genoa to Jib.
