Do You Know this Boat?

Anyone know what boat this might be?

This photo hung in my father’s home office for years. It was taken during a race off Newport Beach sometime in the ’50s or early ’60s. He liked it because he’s on the boat to the far left, Alex Irving’s Sparkle. When I asked him many years later about the boat in the foreground, he didn’t remember what it was.

My father is long gone, but I still have this photo, and I still wonder about that pretty, big (45-50ft?) boat. If anyone knows her name, and if she’s still around, please let me know. And for ‘extra credit’ — why in the world did she have two forward hatches?
