Steeper dive angle in the control room please

Is this modelled in SH3/4? I have never thought to really monitor My boats submerged speed while diving or accending.

Does the boat accellerate and still continue at a higher than normal speed after levelling off (having gained momentum), then gradually reduce speed down to whatever RPMs your electrics are driving?

IN SH3/4 I never noticed the effects of gravity or physics simulated in thii way, but then I was never looking for it.....
Then again, maybe my theroy is wrong?

not really, in a dive its a momentum (or inertia) vs resistance thing which follows the same patterns as aircraft but they are different. the effects of gravity are much less effective on submerged objects containing an air pocket because the floatation cancels out gravity to a large extent. if anything IMO the opposite is true, it would lose speed in a dive due to the increased resistance forces against it trying to push against the forces of resistance, floatation, and pressure changes.

a boat never really levels off, it has a bowl like action as it bottoms out its dive but bouyancy is all part of it too because the dive planes putting force against that bouyancy is what gives you the control or you would forever be in flux going up or down constantly
