Special Notice:

Metric measurements are now standard for Norwalk islands Sharpies.  Most American builders seem quite good at using Metric, it is apparently universal in American science.  
Full size template plans and instructions are included in all current models for optimum NACA Foil sections. 
As far as is practical, and with suitable consents, we will endeavor to put plans purchasers in contact with other owners and builders of Norwalk Islands Sharpies in their areas. 

All plans buyers now receive the new generic manual, and the new plans all include bulkhead shaping for the slightly radiused bottoms. 
Most plans buyers are also opting for the precut kits. especially in Australia and Europe.  We are working on an economical kit manufacturing arrangement in the US.
