[PSUBS-MAILIST] External Frames

[vbra676539 at aol.com]

Look at pics of the PC-8/14. The rings land on the reinforcement collar. I think they are on 19" centers on the 8-window conning tower boats (28"OD tower) and 15" centers on the 6-window boats (24"OD tower). On the other hand, Aquarius and Curasub, along with all the Nektons have no bisected ring at the conning tower centerline at all.

I have a couple of questions reference external framing. The K350 conning tower reinforcement ring straddles three frames.

If moving frames outside, what is to be done with those three frames? Or should they be left in place? 

I notice Gamma has two internal frames and what could be described as a conning tower skirt as opposed to a ring.
