Hi Warbird
The 4.9 is a strong boat, and the wings look like a lot of fun. A speed contest was just run on the San Fransico Bay--your winged 4.9 would be an awesome boat for such an event. Of course, high cartwheeling potential...but we've all taken our "lumps" in the name of speed. Good luck and post some fast GPS tracks whe you get them.
