Welcome to the Shannon Amphfoil Update and Progress Report
THE FOLLOWING ARE SOME QUESTIONS AND ISSUES FROM "FRIENDS OF SHANNON" THAT HAVE BEEN ADDRESSED:
1. What makes the Amphfoil so“revolutionary”?
The Amphfoil is the first transitional speed vessel capable of reaching speeds from 1 mph to 80 mph using a unique three stage speed design planform. There has never been another boat capable of achieving these speeds with market acceptable motion at all speeds, low horsepower usage and safe operation.
A. Stage One: 0-10 mph. The Amphfoil operates as a conventional twin engine boat using hydraulically operated water propellers.
B. Stage Two: 10-40 mph. The Amphfoil uses hydrofoil technology and partial ground effect physics using an air propeller to skim the water’s surface to reduce hull drag and undesirable boat motion.
C. Stage Three: 40 to 80 mph. The Amphfoil lifts above sea conditions using the full 250% efficiency created by ground effect physics to raise the entire craft above sea conditions (1-8 feet) riding on a smooth cushion of air.
