Sunshine II

On July 24, 1928 the fishing boat Sunshine II exploded spectacularly and sank at a dock at 26th St. in Newport Harbor, just minutes after unloading its passengers for the day. The blast could be heard for miles around. Two were injured - including the the boat's engineer, 18-year-old George Dyson, who was blown through the air and into the water. Also, the dock was partly destroyed and the windows of the adjacent fish cannery were blown out. The explosion appeared to have been accidental. 

Either the same boat (rebuilt) or another boat with the same name was destroyed the following year when it ran aground near Laguna Beach in heavy fog.
