By magnetic shoes and firmly grasping an imaginary railing?
Incidentally, was it ever finally determined which is the exact shade of grey to use on the upper hull? I've got 5 different Seaviews in different shades of grey, none of which looks "dead on", all of which are either too light or too dark.
Yes..., it's gray according to John. Actually, it's been discussed around here quite a bit and John probably remembers what the consensus was. I'm not that concerned about the "proper" color, if you look at the photos of the different sized studio models, they all look to be different colors!
