Actually multi-seat submarines. But first ones I've seen that don't look ass.

edit: I didn't know the dolphin ones had 2 seats now. They're OK I guess.

That looks amazing, I want one!!
Hm, can Traveller grav vehicles travel underwater..? Assuming they’re adequately water-proofed of course, which I’d assume at least multi-environment vehicles are. I know spacecraft can, at least from TL13 and onwards.

Why not? I don't see anything that would make grav drives incompatible with underwater use.Annatar Giftbringer said:
I wouldn't assume grav vehicles are generally built to withstand high pressure, but if your particular vehicle is there shouldn't be a problem.
Anything built to handle extreme atmospheres like Venus shouldn't have any problem with a little water?

Kinda what I was thinking too. Perhaps not a deep trench explorer, but a few meters down - especially those that are sealed or protected from various nasty environments.
Like a scout diving down under the surface to get a better look at the partially submerged ruins of an ancient settlement. With a sealed scout-issue air/raft I’m thinking it should be no problem, with g/bike... eh, their field dress is vacc-proof

Decent model should work.
A cheap locally produced vehicle for the home market might not have multi-environment capability. Salt water is a real problem for electronics and rust in ways that water is not.

Something designed for vacuum doesn’t necessarily work as well in an overpressure environment. But I could see where vacc suits (and maybe IISS field dress) might be rated for 2 atmospheres or so. (I’ll let someone else calculate how much that equates to in water depth). Maybe raise the cost of the suit 10% or so for that option?
Emergency vacuum suits and rescue balls would be unlikely to handle very well. One atmosphere in equivalent depth at most.
Our current astronauts often train underwater. Does anyone know if they use their vacc suits or something else?

Approx 10 meters (30 feet) of water depth per atmosphere of pressure.
But as Linwood mentions the pressure is in the wrong direction.
For a standard civilian grav, problems would be the hull strength, and things like seals, and water ingress. They can surely resist 1 atmosphere of pressure in the wrong direction or they would break during fast atmospheric flight.
No idea how water ingress works except that the front and top are obviously protected except when they aren't. A car can drive through rain but a hose pipe in the front of the engine can cause problems.

Usually it’s the seals around access points (doors), pass-thrus (for wiring, fluids, etc) and joins between panels/parts/modules that are of greatest risk. The firewall in a car has at least a half-dozen of these points, none of which are pressure-tight. Electrical connectors designed to meet IP-67 (a high standard in the automotive world for resisting moisture ingression) are only tested to 1 meter depth.
Given the variety of environments a Traveller spacecraft encounters I would expect the standards for it to be higher. But something close to IP-67 might be common for civilian in-atmosphere vehicles.

So basically we might be looking at “yes it should be possible, but perhaps only once, and the vehicle might break down afterwards” ?
With better chance the more protection option the vehicle has, of course.
