For some reason the words "could vanish from sight in as little as 28 seconds" are sticking in my head... could've been from the "Top Ten Subs" show I saw on the Military Channel recently. That would've been for a VIIC.
I'm sure we're not getting to 13-15 m in the times I recorded... I should probably just stay on board and watch the depth meter instead of flying around outside the ship, lol. Or else pick a nice day with calmer seas so it's easier to tell by sight alone.
And now I want that boat!
