Foreword

 

These instructions have been re-typed from the original instructions on the full size plan of the model. 
Many grammar errors have been corrected but others may have crept in. Also the nomenclature may be 
somewhat out of date; e.g. instructions refer to the center internal structural 

member as the “keel” and 

the appendage on the bottom of the hull is called th

e “center

 

board”. 

Not that it is incorrect, but it could 

be misleading.  

The diagrams are photos of the original plan but some areas may be off color due the age of the plan. 
The full size SIDE VIEW and TOP VIEW have been stitched together from photos of small sections of the 
plan. That is why they may not be to scale and have considerable distortion. They are located at the end 
of this manual and may need some zooming-in to see the detail. 

Even though the sections appear in proper order, it would be wise to read over the complete 
instructions before attempting to rush into building this model, especially if you intend to build an RC 
version. If you search in RC GROUPS, VINTAGE BOATS 

for “

Sterling 

Kingfish Build Log” you may find my 

own procedure that I have used for the build, including many modifications and RC revisions.
