(pardon the pun) These are 1500 ton displacement (not DWT) vessels navigating open ocean swells, not cigarette boats bouncing through the chop in Biscayne Bay.
Having said that, it occurs to me the problem might not be the physics related to the sub, but the ocean itself. The waves do seem to be a bit exaggerated, in both amplitude and frequency. The waves in your video are more like what you might expect during storm conditions in very shallow water. Deep water waves just don't behave that way.

Great post lots of good points here...
Id have vote for number two but tone the rolling down just a touch.
I agree with JD in some respects, that these boats were 300' long and HEAVY, however they were rounded hull boats, not a deep v, so im sure they got tossed around roll wise significantly. Its just really hard to 'ball-park" how exactly a wwII sub would behave in a sea. Like we discussed earlier, at 15m/s were looking at around a 15' sea.
Its a tough call. But its a improvement to stock for sure. And even if it is a bit exaggerated from real life (a little) im still in!
after all its supposed to be fun.
