That would be a Cascade 36.
I had never heard of them. Your post got me to look them up in Yachtworld.
Here is one very nice example; 1969/Cascade-Sloop/San-Carlos,-Sonora/Mexico
Hard dodger, 10' dinghy w/ 15hp outboard, and integral anchor platform. $36K
Looks like a great boat!
They seem to be mainly on the west coast of North America...
