Aparently the largest type within reach is 12,5 meters long. This would then be rated for up to 90 people in a survival situation. I am amused by the idea of 90 oil rig workers, all in full gear, squeezing in and buckling up.
Anyways. Point is: I wouldn't want a very small one, like a 20 person boat, from what I have seen I think the 60 person ones are abundant and also a size that seems nice.
Picrel is one of the very stubby ones furnitured as a sort of hotel room or whatevs. That would be way too small.
