I agree, but you stated way back about putting a larger or a 2nd gas tank? Thats going to change things also. If going as far back as you can, and you want a heavy 4 stroke the scuppers are going to be under water all the time.
Thats another good reason not to glass it, different engines at some point.
As to your question, unless you weight all stuff removed and stuff added, there is no way of telling till you get it to the water and float it. I would not glass it!!
