I called BassCat boats and ordered the carpet:
High Quality 24 oz. Exterior Carpet
One issue that I did have was I used the Ash color that is 6 foot wide. My boat was actually 6'2'' at its widest spot right behind the seats.
Many people had said that their carpet was cut liberally (like closer to 7 foot wide) when I got my carpet it was exactly six foot wide. I called
BassCat and asked if I could get a four foot piece of eight foot wide carpet...unfortunately my color (Ash) is only available in six foot wide lengths.
If your boat is wider than six foot they do have colors that are available in either six or eight feet wide. I spliced the carpet it's so thick
that you can't tell it.
