I think the big challenge would be just surviving! No deep diving Gatos or Balaos, you're pushing your luck @200 ft. No radar to warn you.
Could you survive an encounter with the USS England?
...make it to the West Coast and launch a midget into San Fransisco harbor (harbour :rotfl:
)
Take pot-shots at West Coast oil refineries.
Launch a scout plane to look for shipping traffic.
I think it has possiblites.
