Very interesting info Chris. Exactly the same dimensions as the first British Polaris sub - Resolution. I think (but am not certain) that they were based on the same design albeit the conning tower (sail) on Resolution was different and did not have the extra planes. Looking forward to seeing the build photos and the finished product. The bayonet locking ring system seems to be a much better idea than the 'glassed in WTC on my Typhoon. At least you have reasonable access to the motors, dive tanks & speed controllers if anything should go wrong. Not that it should on an Engel kit! Not going to be much room for manouevring in the pond if we are both out together!
