I actually prefer them over a single overnighter. Leave the pass before dark, run a few hours. Maybe even cut down to one motor and take turns watching the radar with the autopilot to run 8 knots and double your effective range. Then wake up and you're 130+++ miles offshore at daylight with a good night of sleep under you belt. And you still have a day and a half to fish. It's a much more enjoyable trip to me. Less rushing and you can try different areas without worrying about time as much.
For the guys in the south that do these extended trips these big center consoles are the best avenue. Speed, range, fishbox capacity, and ice retention are the most important. Of course they don't offer the creature comforts of an express, but we make do.
To the original OP. The 42 Inv is an incredible boat. Looks huge compared to the 36. I do think 1mpg out of a boat that size with a real canyon load in the gulf isn't realistic. That's a tremendous of weight. Light in protected waters you could probably see it.
