GL: Fuel Burn

[bobflower at aol.com]

I have been following the design and production of the Maine Cat P-47 for the last few years. The performance of this boat (from their real life test boat) has been?extraordinary?in speed vs fuel burn. See chart below.

10.13 NMPG at 8.1 knots. !!!!

Even if the numbers are off by a few percent?on the fully finished production model, this will be a wonderful boat in today's fuel issues.
Plus, a draft of only 2.9".
