Re: [PSUBS-MAILIST] Double endcaps sub

Hi Thijs!
 
Where do you live? What is NL?
 
I think it's fun to know where people come from!

Rob,
 
Thank you for your reaction. The pressure hull has a diameter of 1300 mm (520 inch) so you can not lay down in it. I am thinking of a low seat (200 mm) that can be folded. When you want to have a close look at the bottom you would have to sit on your knees, or take a Yoga-course. I hope that changing my position from time to time will help me to reduce the pain. Because i live in a country with poor underwater visibility i need a viewport close to the bottom. 
 
Greatings,

That is a very nice design.  What is the seating position?  Would I be on my hands and knees if I were using the viewport facing forward and down?  Could you lie down in it?
 
Thanks!

I have posted some drawings to:

I have tried to streamline the double endcaps sub. I have added a GRP hull around the pressure hull.  Maybe it looks a little complicated but i think one has to make a mold for only a quater of the GRP hull and use it 3 times. With a little cutting and laminating one could make a hull like that if your are a little inventive (and we all are, are we not?). The keel looks like a box because i don't know yet what it will contain (batteries, VBT, ballast). What i do know is that i want to have a fairing around it. There is a lot of mud in The Netherlands and i don't want to stick in it. The idea is to bolt the fairing to the drop-ballast. So if you get stuck you can drop the ballast together with the fairing and you are free again. 
 
The next thing i will do is to try to make some calculations on the stability.
 
I would like to hear what you think about it.
 
Greatings
