I do not have an experience with L500, only L400, but I believe it is general enough to be of help. First thing to consider is the very narrow angle between the jib
traveler and the center of the boat. This makes the jib
flying nicely only at colsewinded angles.
(or actually code 0 that was supplied to me under the gennaker guise) is very effective between 80 - 140 degrees apparent. In that it complements very effectivele the jib range.
I did use the gennaker at lower angles up and over 150 deg apparent but it tends to flap.
The usual stuff applies, e.g. when you are over 90-100 deg you need to bear down in gusts, under that you may go up under gusts and loose the sail to spill wind
The higher you point with the gennaker - you need more tension on its hallyard and vice versa.
is straightforward. It is an endless line, going round the furler
at the bowsprit
end and round a free floating block at the deck
. The free block it tied with a robust bungee to the railing. Pay attention to ensure that the furling line has a free path to do its job.
Furling is best done going downwind to lower apparent wind pressure. Someone needs to help with keeping the right amount of tension on the sheet, not to much as to make the furling difficult and not too little, which will cause the sail to furl loose. It is very easy to find the right tension when on the job.
The interesting thing is how to jibe. At this point of time, I furl the sail and unroll it on the other tack. I did not try to pass the sail between its hallyard and the front stay.
