I, too, had been watching that ship come together over the past few years. Amazing, when you think of the river at that point. I saw it at St. Augustine 2 days ago while it was being sea trialed. Their tender/chase boat is an (approx) 27' twin engine Intrepid Center Console.
A quick conversation with a couple of people in the know advised they splashed it at midnight, given for the full moon/highest tide. If I remember correctly, it's still only drafted 10' or so. Would have loved to been there for that! I just wonder if they motored or were tugged to St. Augustine?
I tried to get some pics, but was on the move solo and had more important things to tend to. Still impressive by any stretch.
