[PSUBS-MAILIST] External K250 stiffeners?

[Daniel Lance via Personal_Submersibles]

Ian,
When I build another sub I will definately put the stiffeners on the
outside . Yes , there is more welding involved ( they must have full
penetration welds ) . But with the hull on a set of rollers you can do all
the welding standing up instead of crawling around on your hands and knees
in a cramped space .

Hi

keeping the K250 stiffen questions momentum going.

I'm restore-modding a early K250 (more like the last of VAST MK3s sold as a
K250 after VAST and Kittredge parted ways).  One change I'm considering
fitting external stiffeners to replace the internal stiffing/ballast tank
structure.

Also, if I was building from scratch I would be making the same
consideration.

Anybody else thinking about this or have thoughts about this?

Thanks,
  Ian.
