Several have been built. One was jet powered and later converted to an I/O; all the rest are twin outboard powered and have dedicated pump engines, usually V-8 gas engines. Differences among them are mostly fire  pump related.

Fire companies include Chesapeake, VA, Lake George Village, NY,  Milford, CT, Bolton, NY, Hampton, NH, and Stony Point, NY.

10m (32’ 8” X 11’) Walk Around
A handsome 10m diesel jet pleasure sport fisherman walk around. This boat has a lovely interior as is shown in the following pictures. The owner has not wanted to paint the exterior on the grounds of reduced maintenance.  It is sand blasted to a dull quite uniform gray and looks better than it does in the pictures included here. The interior is simply stated elegance in the Herreshoff tradition.
