Anyone know if the 2001 motion cat 35 footers were a all composites construction or did they use plywood and balsa coring? Also what material did they use for fuel tanks , someone said that they were fiberglass? Not so sure that is a good idea ???

I have one. Mine is a 2005 and has Fiberglass tanks and there is absolutely nothing wrong with them. I can tell you they are awesome boats. I just went out today in some true 3-4 with an occasional bigger roller in between and It was like being in a Cadillac. My friend who was with me was shocked at how great it rode.
