Are you after an air bag system or a water bag system?

Water bag system as this seemed to be the easyest one to do

What size and type of boat is it going in, and what kind of volume are you looking to displace?

A water pump based bag system is generally best suited to smaller models with low waterlines- the opposite of what you have.

 better option would be a hard tank, with a centrifugal pump. This will pump quickly. there are also commercial alternatives like R&R and OTW, who can supply modules suitable for that size of boat.

That would require a great deal of explanation- we're talking books worth of info.

I suggest getting yourself some reading matter. All the Traplet books on Model Submarines are worth getting. A subscription to the Sub Committee will get you online access to the full back catalogue of over 100 issues of the club magazine.

Personally i would say you are coming into this hobby at the sharp end, and would recommend you start with a good kit which has all wrinkles ironed out, and save the U-class for your second project.
