At the moment i do not have photos of my configuration. What i have are some they took when laminating the bar in. The deck
is no reinforced and cannot take the forces. So you will have to construct a fixingpoint strong enough on the bottom below the bed
in the frontcabin.
I think you cannot have a selftacking jib on the SO 43ds. The mast
is far upfront so that leaves you with a small jib anyway. If you want it to be selftacking it would be even smaller and also you will need a traveller in frot of the mast. Because of the small size of the jib it is very easy to tack. In my case of course you need an extra car on the rails port and starboard.
At the end of this month i will probably go to my boat and if you want i can take some photos.
