I thank my late father for passing on to me his obsession with military history, planes and anything ships. I loved this tour. We spent almost three hours on the boat, investigating any space we could for the "cheap" tour we did. We just bought the cheaper ticket because it still allowed access into quite a few interior spaces and we also added it on to the waterside tour of the naval shipyard. Both tickets were purchased at the window of the Nauticus center. Such a cool family activity.
