Dear Hakan,
it had always been an argument against the Egner Flyer when it came up. Its not practical to have two hulls non-detachable for transport, storage or repair. In contrast, nowadays the world is filled with Egner's Flyer with glued beams. Like many decisions in the A-class, sailors choose more for the ultimate sailing vessel than placing practical considerations in front. A-cat is performance orientated and performance orientated sailor will always choose for the fastest belived boat. Glued beams are believed to be stiffer so the ambitious sailors will go for it.
There might be other sailors who place practical considerations first but those are not the ones who round a mark in front.
It is good M comes up with a new design. Lets hope its more competitive and looks less outdated than the previous one and also an update on the shape and size of the foils will be included.
If M want to regain a serious % in the market, its only chance is to come up with a killer package. It has to be at least as fast as other designs while looking more sexy. This means M has also to consider if the current lonely philosophie in mast design is still something to continue for the future... if you want to have a future.
Just my thoughts.
