I note a few posts where prospective buyers are doing what I did when I was looking at 26X and 26M models and trying to decide between them.

I found the attached documents that might be helpful.

It is worth noting that there isn't just one version of each X and M they did evolve during the production runs for example the early M's have the galley abeam just behind the heads where the later ones have the moving galley on the port side.

Please note I'm not intending to start a 'my boat is better than your boat' debate and the documents are the opinions of the original authors, not me! but I don't think there is anything factually wrong in them.
