bscott,
The hatch is easy to remove.
Either side hatch rail would work, but I'll describe the port hatch rail.
Remove the switch panel to access the aft most rail nut/screw.
They are long screws, so use a deep socket and phillips.
Remove that one and then the interior trim plugs for the next five going forward to get at those nuts.
The trim plugs have a section in the diameter that pushes in to "uncatch" the hole.
A thin bladed screwdriver works okay
Your arms are long enough with hatch open, no help required
The rail material itself is somewhat flexable, so no worries about it breaking.
Also, the factory sealant is also flexable, (not 5200), also a good thing.
Once the rail is bent towards the port and up, the hatch slides back and up, also towards the port, and it's yours.
No more bending the rail than what is needed works fine.
I suppose if you get nervous, all ten screws could come up to remove the rail, but really not required.
If you plan to do the velcro mod, reseal the screws with something easy for any future removes.
I used just a simple plumbers putty under the screw heads and around the shafts and it's worked fine going on three years.
Still waiting for the velcro pile to wear thin needing to be replaced.
Be sure to have some excess velcro length so you can turn the ends up and on the top side of the hatch for a few inches.
This really protects both leading edges so they don't peel off in normal use.
On EDIT:
The X and M are a little different in the removal methods, I do believe, and I described the M.
Sorry.
I need to read better.
But maybe someone else can use the info.
