Here's why:
* Early Cinema: Filmmaking in 1902 was in its infancy. While "dissolving effects" were technically possible, they were quite complex to achieve and likely not used in short, documentary-style films about yacht races.
* No Record: There's no documented evidence of a series of films titled "Yacht Race Pictures with Dissolving Effects - 1902".
It's possible you're thinking of something else, or the title is a fictional invention.
