Driving bans and wide load permits

Thanks for looking both of you! It’s convoi exceptionnel cat 1, so I was just wondering if 7.5t trumps convoi or (most probably) vice versa. It’s a pontoon boat so not farming really!
It’s just the fact from loading tomorrow (Saturday) in Poland , means I can’t get into Germany until 23:00 on Monday (under convoi rules). And then by the time I ever make it across Germany I’m gonna hit the French holiday on the Tuesday, which for convoi rules starts 12:00 Monday until 06:00 Wednesday!! It’s gonna be a slow week!
