Ship Hull Reflect Issue

Serengeti (Rhino WIP)
1

For the marine industry I am testing out SubD for hull modeling. Especially ships with aft bulbs for the propeller are very challenging with NURBS and not to mention twin skeg arrangements.
It is very useful that Rhino7 SubD offers the reflect feature as we always have a similar shape on both sides of the center line.
However, when I reflect a hull to be able to continue in the aft ship, something weird is happening at the bow area. Can someone please take a look and tell me what I am doing wrong or how I can repair this?
I’d like to add an edge at center line again.

Thank you in advance.

I think this is the same issue descibed here.
Allready filed on Youtrack too.

You need to remove the triangles or move the edge into the model’s boundaries.
