As for fuel usage - most guys from Renfrew tend to fish just off the west end of the closure near the border. That's about at 27mile run from Renfrew. Depending on whether you're a deep-V or a flatter bottom boat (like a C-Dory), and depending on how hast you want to run, your fuel mileage will range someplace between 1.5 and 6mpg (the latter can be achieve by running at about hull speed or 5-6kts). Assuming a deep V and 20kts, you're probably at 2MPG so figure about 15gal (~57liters) each way. Alot that much again for safety and a little for trolling.
