[Public-List] A30 Hull Prismatic Coefficient

[David A. Bardsley]

   Gordon,
   Thanks for the pointer.
   I've removed the PO's vetus diesel and am installing a 10kW electric
   drive with a completely new transmission.  I'm free to pick an
   arbitrary ratio to maximize (hopefully) the performance of my 2 blade
   13-8 prop.
   As you can imagine I'vd been spending a lot of time at Google
   University and on the vic prop calculator!

   Check out Skene’s Elements of Yacht Design.  There will be information
   there to allow you to make a good estimate.
   I reckon you already know that if your boat has an Atomic IV, it has
   direct 1:1 drive.

     I'm designing my drive's reduction ratio and the resource at my
     disposal requires our A30's prismatic coefficient as a part of the
   drag
     calculation.
     Can anyone share a decent figure for our craft?
