My understanding is that Corian was an option,not part of the comfort pack which as you have mentioned focused mainly on the water maker,twin Racor filters, larger water maker,electric heads,larger cooker,electric fans,etc. I also thought that originally the Yanmar 100hp was part of the comfort pack?
It does seem that towards the end of the production of Super Maramus there was a certain amount of cross over with fixtures.
Joel or Olivier would know for sure.
