The Grinnells were among the leading citizens of New Bedford, very important yachtsmen --- and important Herreshoff customers. Herreshoff yachts ordered by the Grinnells included:
#213p Quickstep (Steam yacht) for Grinnell, Russell & Frederick
#608s Rugosa (Sloop) for Grinnell, Russell
#616s Bambino (Sloop) for Grinnell, Lawrence (now owned by the Herreshoff Museum)
#703s Flying Cloud (Cruising Sloop) for Grinnell, F. B. & L.
#945s Juno (12.5 Twelve-and-a-half) for Grinnell, Russell
#983s Rugosa II (40 NY Forty Yawl) for Grinnell, Russell (now owned by Halsey Herreshoff)
#1393s [12 1/2 for Lawrence Grinnell] (12.5 Twelve-and-a-half) for Grinnell, Lawrence
L. Howland's history of the New Beford Yacht Club contains a lot of material about the Grinnells --- too much to quote here. But definitely worth (and fun!) reading.
Juno was sailed by Russ Grinnell, Jr., son of Russell Grinnell, nephew of Lawrence Grinnell, and great-son of Frederick Grinnell.
