Thanks for letting us know where you're at John.

I wish I had had an interest in subs 30 years ago.

I started this quest 2 years back at age 51. However

had been diving for 30 years.

You could go a long way in this field with a bit of enthusiasm.

As Sean says, becoming a certified diver is an invaluable tool. You experience & become aware of the

environment you are designing your sub for. Also there's are a lot of basic knowledge that's applicable to

submarines. You could one day build your large sub, but I would encourage you to look at building a small one first

& apply that experience to your next build.

Look forward to hearing how you are getting on. Let us know what you think of the Busby book.

Regards Alan

Ok, since the whole galaxy (lie) insists on knowing my plans I will say them and only once.

I am a student, my age is of no importance as long as one day I build a Submarine (to me that is, I am not a kid). I have friends that will help and so I have a team.

Right now the sub is only in design stage and will be like that until I have the money and the support. I am trying to make the boat simple as possible so

I have taken out some features I had said on my last posts. The sub will be for exploration, researching and wreck diving. I will try to keep inside a budget of 200000 USD.

I am studying electrical engineering and computer science and some physics. I still have some problems like "How to design the stern section of the sub" "How to install a shaft and propeller (and not let lots of water in)" "Control dive plane or move them" And Other problems.

The reason why I am doing this now is because I want to get a head start and not waist a lot of time or at least have an idea of what to do. This is about the only place where I can receive help. I ask my instructors about pressure hulls and I end up telling them it’s a sub and they look at me like I'm a crazy man. I have searched half the internet of electric motors that can give me speeds of 8 knots and I find little kids toys(exaggeration). I assure everyone I will research a lot lot lot more, even though some of these concepts are somewhat confusing (abs hull sheet).

I will say that I am determined to do this, if I ever do build the sub and your ages are not 100 I would very much like to meet everyone in a Psub meeting.

I am not mad it just my way of saying things, just don’t comment on my stupidity.

Current sub dimensions: length 56 ft, diameter 7 ft height 15 ft wall thickness 1/2 inch and 42 ft cylinder part. I may change the total length to 50 ft I don’t know how much space the stern section needs yet. I am planning on having x type rudders and dive planes also 5 blades for a prop.

Thank you very much.

John
