Ice yacht Whiff in miniature ..

Ice Yacht Whiff; model built by Jacob Buckhout. 

FDR was an avid collector of ship models. One can spends hours checking out the tremendous collections of models (not all are on display of course)  at the Roosevelt Library. There are two ice yacht models - neither of which are on display. The Mo-Wa-The was built by J. Sterling Bird. See pictures of that model here.
The Whiff model was built by Jacob Buckhout around 1875. It is a fabulous example of the early side-railer design that Buckhout was building in the 1860s & 1870s.  Some of the history of Whiff can be found here.
The model was set up in a work room in the basement of the museum, thus the backdrop wasn't ideal. But you can see the detail fairly well.

I love the detail in the cockpit & the tiller. 

Detail of gaff and hoist rigging. The sail is the only piece showing wear  on the model.

Graceful lines of the cockpit. 

Alternating strips of spruce & red cedar form the floor of the cockpit, as on the real boat.

There is a little rot, or wear in the cockpit, starboard side against the outer edge. 

Mast step detail. Mast stepped directly over the runner plank.
