Gents and Ladies:

I am new to this "board" but have read all the previous comments.  It
appears the "track" has been lost.  First of all:
1.  What material to use in building?  No  conclusion has been reached.
I am familiar with Cape Horn yachts (had a  bit to do with their advertising).
To me steel is the first and best  choice with "fiberglass" in second place.

2.  Stability:  Cape Horn's are "self  righting" by design. A minimum of 

140 degree roll recovery is required  regardless of construction material.

    Flopperstoppers and "zero  speed" stabilizers mandatory with 

sufficient "over kill" to not work the system  to death.

3.  Length:  Minimum of 50 feet.   This will give decent speed, beam and 

volume.

4.  Accommodations:  I am not one for a  "MASTER" stateroom.  All you do 

there is sleep and use the  bathroom/shower............so........would much
rather have more "living" space  with more than adequate storage space.
Therefore:  mid-ship main  stateroom, office area, and guest/crew quarters for 2-4
guests and 1-2  crew.  (Crew for "long" passages).

5.  Propulsion:  Single engine with "get  to a safe place" wing engine.  

Wing engine to have 100 gallon fuel supply  that is "totally separate" from
main fuel supply.  The wing engine  fuel supply to be plumbed into the main
fuel supply so if you need to burn more  than 100 gallons, it's
available---ASSUMING the main fuel supply was not the  issue that caused the main engine to
puke.

6.  Fuel and Filters:  The fuel  system--both wing and main 

supplies--able to be polished to a minimum of 2  microns therefore, enough storage for
sufficient fuel filters--ok, someone else  pick a number for "sufficient."
Sufficient fuel for 3000 nautical  miles with 10% reserve--ASSUMING "standard",
whatever that is, conditions.  (I am a pilot so am used to using Boeing's 80%
probability data). Is there some  way to "polish" the fuel as it is being pumped
aboard without causing a  significant slowdown in flow rate--say less than
25% slowdown rate?

7.  Electricity:  120/60 and 240/50  capability standard.  1000 amp hours 

battery reserve  minimum.  5000 watt Inverter capability ( is that enough/too
much/what is a reasonable watt number)?  Main generator with sufficient
power to run the boat at no more than 85% rated engine capability.  Secondary
generator with sufficient power to run 80% of the total load at 85%  rated
engine capability.  Sufficient main engine generator to keep house  and engine
start batteries charged run the water-maker, etc.  Wing engine  generator to
handle start batteries and........frankly I haven't a clue as to  how big the wing
engine generator should be.....help!

Clear and easy load shedding capability--airplanes  can do it 

automatically, why not yachts?

8.  Electronics:  Triple redundancies  except for radar--dual redundancy 

should be sufficient.

9.  Interior furnishings:  I am not much  for teak--yep looks nice, takes 

way too much work to keep looking  nice.............    Earth tones.

10.  Decks:  Walk around all sides  required--24 inches wide?  More?  

Guard rails.........OSHA minimum  requirements plus 25% regarding impact
resistance.  There are systems  available that allow one to "hook" on one time and
more around without  having to "unhook and rehook" at each sanction.  Built in
non-skid on  all exterior walking surfaces.

11.  Ground tackle:  OVERSIZED but not  ridiculously so.  Chain rodes. 

300 feet each?  More?  2 anchors  with 3rd as a spare. Wash down capability

12.  Fly bridge--yep, I like to be  outside--with hardtop.

13.  Wing stations--yep--port, starboard,  forward and aft.

14.  Bow and stern thrusters--yep.   Hydraulic or electric?  I lean 

toward hydraulic but...........am open

15.  Heads--master, day, pilot house and  guest with fresh and salt water 

flush.

16.  Galley--ok, haven't a clue--need wife  input although I do a goodly 

amount of the cooking at home.

Any comments?

Don
