Andromeda Specifications

The Andromeda ketch is a rare breed with an unknown number of fiberglass and/or Ferro-cement versions made by DIY enthusiasts/boat builders.  While the Andromeda is better known, Bruce Bingham made a slight variation in the bow and stern flair of the Andromeda design to create the "Christina" version.  Only 2 Christina fiberglass hulls were made in the Bingham factory, and to our knowledge, no Andromeda's were factory made. Bruce's book -- Ferro Cement Design Techniques and Application -- gives a great deal of insight into the Andromeda's design characteristics, and the line drawings highlight the subtle differences between the two versions.

Phoenix is hull #1 of the Christina line and an outlier among both the Christina's and Andromeda's, as she is the only one we know of with a bow sprit (extending the foot of the headsail for more sail area) and an additional stays’l rig (for a storm sail).  This will provide a variety of different sail configurations for the various sailing conditions we may encounter.

So, for those who are curious, here are the Andromeda specs (Phoenix is a Christina):

LOA                                     48' (54' for Phoenix with bow sprit)
LOD                                     48' (Christina version 49')
LWL                                     40'
Beam                                   14' 6"
Draft                                    6' 6"
Displacement                    38,000 lbs.
Ballast                                 19,000 lbs.
Sail area                              1,257 ft (100% foresail and mizzen)
Mast height                       57'   (above water line)
Sail Area/Displacement   17.9
Tankage:
               Water                   240 gallons
               Fuel                       228 gallons
               Holding                103 gallons
