I seriously considered making the doors out of Starboard after reading a previous post of yours last year or so. It seems like the ideal material.
I looked at a boat that had 3/4" Starboard sliding doors last summer. The owner complained that when it got hot, the door would warp slightly and make opening and closing difficult. 1" like you suggested would be more stiff but the tracks on Sandpiper is made for a 3/4" thick door. I even looked at shaving 1/4" off the top and bottom to make the door fit but other reasons had me look at other methods.
Fiberglass encapsulated doors will be 0 maintenance too.
I listed the reasons for not using it on the next thread.
