It Happened One Night

I was watching this movie (from 1934, with Clarke Gable and Claudette Colbert).

The opening sequence is on a yacht, and there are at least two shots with what I think is an I14 in the picture.  The sail appears to have an I14 insignia, though faded, but for me the plumb bow is the real giveaway.  The mast is a gunter-rig.

I'll see if I can get a picture or two up.
