Since this is for livery, I suggest you make each electric motor drive independent of each other. Each motor would have its own controller and battery bank. Having separate motor control also makes docking a snap since you can have one in forward and one in reverse.
You also need to think about infrastructure. You'll need AC power and a charger, too. Rivers flood, so the meter base/safety switch will have to be above the 100-year flood level.
