OOC:
Ok, so I broke down and made a schedule to see how this would all work out and figured a visual may be nice to have. Here's two options, 1 for 6 people on duty and 1 for 5 people on. 6 on is easiest. Essentially everyone would (once it all gets rolling) be on for 16 straight hours and then long rest for 8. The 5 on can be done, but mechanically works out for a weird schedule that ends up being work 16, off 16, work 16, off 8. I leave it to you guys how you want to manage. If you go 6 on, it would be 4 rowers, 1 navigator/tiller, and one lookout (so I'd give you fast speed, advantaged maneuverability, and advantaged perception). If you go 5 on, it would be 4 rowers, 1 navigator/tiller (fast speed, advantaged maneuverability, normal perception).
