HIN decode help needed

[RJSWFL]

I recently purchased my first Seacraft. Love the boat so far. I was told it started life as a Savage, but was converted to side console by PO. Lady at DMV was confused by last (2) digits being 78 but title saying 79. I told her I assumed 10 meant Oct 78 production. HIN is:

SECG30021078

Can anyone here tell me what does the G stand for? Savage? I've read S meant Savage in other threads. Does this mean this hull was the #002 Savage for 1979? Or the #002 23' of any configuration for 1979? It makes sense that 10/78 would be early on in the production run.

Thanks for any help.
