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.</font>

<table cellspacing="0" cellpadding="0" border="0"><tbody><tr><td valign="top">I have a couple of questions reference external framing. The K350 conning tower reinforcement ring straddles three frames.<br>
<br>
If moving frames outside, what is to be done with those three frames? Or should they be left in place? <br>
<br>
I notice Gamma has two internal frames and what could be described as a conning tower skirt as opposed to a ring.<br>
