Lee, let me add something. I have a copy of Nautech Maritime's 1978 catalog. It prominently features the NC -2, and there is no mention of the NC-77. This tells me that if the NC- 77 was introduced in 1978, that it was so late in the year that it wasn't even previewed in this catalog. Unfortunately, I don't remember when the galley's were frozen or when it hit the mail. I do remember that I had an NC-77 when we went off in Bagheera which we commissioned new in Seabrook, TX, late in 1979. The boat we started with in 1978 was Nereus, a 41 foot ketch.
