Dead Lizzard said "It usually launches running with 14x22 NRS tubes instead of the 14x19 JPW tubes because of the gear capacity"
We also make a 22 inch Royal flush model for those who want more capacity that way, and we can make the tubes longer with blunted end cutthroat tubes ends. I usually make the recomendation for extra cargo capacity by going to the longer tubes. However we had a customer form St Johns AZ who had us build a cutthroat 2 with blunt ends and 16 inch tubes so he could navigate the San Francisco river in NM easier. This all gets very interesting, trying to understand what is the most improtant issue and the way to adress it. I simplify it by asking how much beer you want to take.
Interesting to see that the farme got a new set of tubes.
If interested in different tube sizes and configurations even if they are not on our cutthroat frames have a look at this web page.

The cutthroat does come in a 10 inch wider model. Still only 24 inches between the tubes, and narrower than most other small cats. If you are interested.
