Based on their Lat, / Lon. coordinates, they have about 25 miles to go. I will stick my neck out, be confident and be bold and congratulate to the boys. :) 25 miles, even if they loose a motor, drive or prop, you can get in with one at 15-20 MPH and beat the time. So.. Good job. :ernaehrung004:

On their test run, you can actually see half or more of the props are out of the water, even with out "re-entry". Some one need to do some testing, may be more blades and smaller, to reduce the stress levels on the surface. I don't know just guessing, but I wish them luck. Vibrating could be detrimental, but sometimes faster is actually better to reduce the vibration.

Just a couple of points, Peter. The prop sizes we run are for optimum performance. Going to a smaller prop will effect performance so we want a solution that does not hurt our performance / efficiency. The answer as I see it is making them of a material that will withstand the beating. I imagine that the cost of exotic materials like titanium etc would just be too cost prohibitive so we get what we can out of what we got. LOL As for vibration the only time I have experienced that is when a blade comes off and then the wise thing to do is shut er down. With the trip I can stay on plane with any 2 drives to get back to port. It's really tough to change a prop in the water and amazed that Tyson was able to do that in good time and get back up running. He makes a great partner in this venture for Chris. Outstanding work, guys.

Where is the finish line in Bermuda? ... as in the actual port?

Have you ever looked into inconel? I have no idea what it would cost, but it's common to see it used in harsh environments.

Thanks Bob, I understand the current prop designs and size as far as "optimum" performance. I didn't mean "smaller" diameter. I was thinking more on the line of "smaller" blades and may be more of them. Over all water displacement based on surface, rake, etc. and RPM's. While not the same ting, but high output and speed props, or impellers if you will are commonly used in other industry. So.. just "take" out one of those high output pump impellers and snap it on a drive. :) ( just kidding, but there is a thought)

Hope they get some sort of warm welcome or congrats when they arrive

along with Peter Hledin in Bermuda shorts and shirt waiting on the dock to help tie up ......with a new set of props

They can see land and lights!

i just saw a set of inconel headers off a nascar car, i was amazed they were making headers out of iconel! 10 lbs a side...
