What kind of wood is NE Dory rubrails?

I need to make plugs for the rubrails, but seem to have misplaced the scrap material from the extra length... so, I'm going to need to run to the lumber yard tomorrow and pick up some lumber to make 50 or so plugs.  I believe it's cedar... but I want to make sure.

Thanks,
Giggin

Normally mahogany.
