The 40 Cat has plenty of room to keep fish: two fish boxes below the aft cockpit — 268 gallons to starboard and 414 gallons to port — and two 158-gallon boxes forward. I also found two 8-foot-long dry lockers forward. To clean up, the 40 Cat has a raw-water washdown, as well as a freshwater washdown fed by an 82-gallon freshwater capacity.
Powered by quad Mercury 350 Verado outboards, the double-stepped hull reached 30 mph within 10 seconds. With a load of seven crewmembers, 400 gallons of fuel, 45 gallons of fresh water, 500 pounds of fish, 300 pounds of ice, and 180 gallons of livewell water, the 40 Cat reached a top speed of 71 mph at 6,400 rpm. Best fuel efficiency occurred at 4,000 rpm and 40 mph, where the quad outboards burned 41.8 gph for about 1 mpg.
