Hugh, Very good submarine! It seems as if you have more room than a standard psub. Well kept. I like your angle indicators...just aquired one simular. Once operational, where do you ihtend to get her wet? Any sonar be it passive or active aboard? Ever thought of building one? I can help.

I was thinking of putting some planes on the Comsub. It has had a rudder retrofitted about 12” x 24” high but it is in the prop wash. I am just reconnecting the aft lateral thruster and reconditioning all the hydraulics. AThe hydraulic pump is really noisy so I’m thinking of putting a pulse suppressor on and a 5 litre accumulator with a pressure switch. Otherwise I think it will drive me nuts. I want to go down for some peace and quiet.
I have uploaded a few photos of the internals and bits on the projects page under “Hugh Fulton” Comsub.
Regards, Hugh

Hugh, I am still working on my presentation for the upcoming Conference and need to figure the various increases in size for the control surfaces for the Seehunde. Just remember in the back of my mind the large tail surfaces on some Perry submersibles...I may be wrong but it just sticks in the back on my mind. Some of the images in Busby’s Manned Submersibles might be of assistance.
After writing the previous email and recollecting on the classes I attended over lunch while at Electric Boat, for larger Navy subs that have the capability to operate at higher speeds, the control surfaces are relatively small when compared to the size of a hull (effectiveness of control surfaces goes up with speed). The minimum effective speed for these surfaces was 3 knots. For a PSUB, the control surfaces are larger in area compared to hull size so may be more effective. Unfortunately for us, there is very little in the way of published naval architecture references for submersible design and even less for subs the size of the typical PSUB. R/Jay

For the uninitiated what size were they? Mm or inches will do. Approximations gratefully accepted. Would be helpful. 2 sq ft, 6 sq ft? approx length and breadth. Hugh
