My father started cruising islands in a rented sailboat with our first trip through the Virgin Islands. We were accompanied by two other couples, so we rafted 3 boats together at night. The snorkeling was amazing back in 1980 and I spent many hours in the water. This was part of our extended tour on our return from Rio de Janeiro to the States. 

In addition, to swimming and sailing and going to beaches, I was given the opportunity to try sail boarding. I tried and tried to tack to get back to the boat, but it would turn me around no matter what I did. Eventually my dad came out in the dingy to save me. He understood I was frustrated and embarrassed, so he was very gentle about asking if I wanted help. I returned to the boat a little worse for wear, but all good. That was a good trip, two weeks in paradise.

My father Harold who was 11 years his senior, loved him very much. They had a lot in common. Both studied engineering and I see he was a bird watcher as well ,when older.
What I remember very vividly, although I must have been 3 or4 years old and Harry my brother 4 or 5,  is how kind and patient he was!!!!  
We were left for the night at Julia's house in Vicente López. I suppose there was a wedding or some family event.  And Georgie ,as everyone called him  , was our babysitter.
And we behaved very badly not wanting to go to sleep!! Laughing and saying 'estupido' to each other which was the worst word we knew.
And he very kindly put us to bed again and explained that that was not a nice word.  We were quite ashamed and I knew that I had been rude!!!   Imagine I still remember the upstairs bedroom ,an attic, I believe, and Georgie's face when he tucked us in. And I am 73 now!!!!
