After discussions and advice on the Jeanneau Forum from Rene460 - see:
I ordered the Bimini shown in the pictures below and am happy with it.
It's overall dimensions are just 1.35m by 3.1m but mostly I found a shadowed place this summer. Also it protected me (mostly) from getting too wet in heavy rain.
The delivered version relies on belt strap fixing towards forward and aftwards. I replaced the aftwards fixing with stainless steel tubes and added a 100W Solarpanel with a fixing to the aftwards Bimini support tube.
