Have you read about https://en.wikipedia.org/wiki/Tristan_da_Cunha?
In 1974 his boat was the first to land on the world's most isolated island, Tristan da Cuhna. He had built the 6 meter long boat Bris in his mother's basement. The island has no harbor but the boat was lifted up and placed on the beach. There he got a job as a math teacher.
