Hatches and doors

[Poacher886]

I've only just started playing SH5, so im still sussing it out....for instance, if i leave the conning tower hatch open before diving and im the last man on the bridge, does it fill with water?

Also if before entering battle and getting hit, if i've closed all the doors inside, will it restrict flooding?

And, i order to dive but remain on the bridge, do i teleport inside the boat??
