Identification of a classic wooden cabin cruiser plan

Hi - I just picked up an older classic wooded cabin cruiser. It is 30' long and planked with cedar fastened by square head, clinch nails. I've attached a couple of photos and the line drawing that the former owner had. It has similar lines to many classic cruisers but the pilot house appears to be significantly different than anything else I've seen pictures of.

There's currently a temporary structure to protect the cabin and pilot house areas, but the line drawing shows the intended design.

She was named Mi Toi in her last life and her port was Tacoma, WA.

I'm looking for any information on the design, plans, photos, etc as to who made this and what it was fitted out like.

The former owner believes it was built in 1947.

Thanks for your help!
