W&B question with Borer increased GW

Hello all,

I have a PA-12 with the Borer gross weight increase, SA190AL. I have the approved STC, but not the technical documents that support it. I have been able to get some reference documents from the STC from F. Atlee Dodge, but they were unable to answer the following question:

In the seaplane configuration, does the forward CG envelope continue up the PA-12S slope to 1935lb (~16-ish")? Or does the forward CG point at Max Gross jump up to 1935 at 15.2"? Or even better, does it allow all weights between 9.2-18.2"?

Thank you,
Silas

Bump.

Direct your question to somebody with the Crosswinds gross increase. The two mods are the same. I don't recall any change to envelope with the gross increase but I don't remember it well.
