[PSUBS-MAILIST] sea state

Fri Jul 15 13:13:19 EDT 2016

Hi Alan,

I was looking forward to the video, but that's a pdf file! I would describe
a K250 as a big hole in the water waiting to fill up whenever the hatch is
open, but I agree Emile's boat is something entirely different. Also, in my
experience there is a huge difference between boarding one person or two.
If it's just me, I can time it better and slam the hatch right behind me,
but if there's someone inside the sub before I get in, it slows down the
move a lot and makes me a whole lot more worried about the consequence of a
mishap. I can quite see a situation where a two person load would be too
dangerous but a one person dive might still be accomplished.

Best,

Alec
