Here’s a photo of the Aeromarine model 75 flying boat. Each model 75 was a conversion of a Curtiss F-5L or Curtiss H-16 maritime patrol aircraft originally built for the U. S. Navy.
Aeromarine West Indies Airways offered these trips to Bimini and the Bahamas during the “prohibition” era. The era when alcohol was banned in the United States. Bimini was the closest island in the Caribbean with legalized booze or the closest “wet spot” as it was called back then. This was definitely only a luxury that the country’s wealthiest could afford.
The low flying flight was estimated to be about 25-40 minutes.
