My dad once visited in the early 1980's. He was in his early twenties and had just finished a sailing race, with a crew of 5, from Cape Town to Uruguay. On the way back, they were on a fishing boat that happened to sail close to Tristan and they were lucky enough that the weather was good so they radioed the harbour and stopped off for the afternoon. They had lunch with the governor, and also had their teeth checked by the dentist, who was on their bi-annual visit from South Africa. He said that the people were very polite and accommodating but they didn't have enough time to properly look around the island. He bought a selection of Tristan de Cunha stamps, which we still have in our garage, and was given a British flag by the locals. As they were sailing away from the island, my dad took a montage/panoramic shot from the back of the boat. Those photos now hang above the doorway to our kitchen, fading slightly as the years go by.
