I’m searching for a children’s chapter book that I read and loved when I was about 10 or 11 in the early 1970s. All I remember about it is that it was about a boy who lived in an apartment building near Central Park, and in the afternoons he and an older man (perhaps his grandfather?) would sail his toy boat in Central Park. (I’m not thinking of Stuart Little!) I think the apartment doorman might have been a character as well. My guess is that the book was written sometime in the mid-1960s.
Judy Blume’s Superfudge books take place near Central Park, in a NYC apartment building, but there’s no boats.
The Teddy Bear Habit by James Lincoln Collier is also in NYC–it’s been a very long time since I read it, but I thought there was a bit about boats in Central Park.
I think there’s also a scene in The Saturdays, by Elizabeth Enright, where Oliver sails a boat in Central Park.
Thanks so much — I’ll check them out!
