Hey Ray, I can see that now that I look at the pictures of you in Mark's sub, and the promo pictures of some other students in the sub with a solid hatch on. Ya the dome was the weakest point on the original design, so changing the hatch would make since for deeper diving. Sitting lower and looking thru the small viewport in the conning tower, makes it much easier to also take a look thru the lower forward viewport without having to slouch down so much.
