Passage Stats, Tuamotus to Hawaii

Well we arrived in Hilo yesterday just at Noon. We were tied up by 12:30 and by 12:31 I was drinking a cold beer thanks to Jon on Pura Vida. The crew on Pura Vida took us out to dinner at Cronies restaurant for huge burgers and beers. I have to say that is the nicest landfall welcome we have ever had!

Here are a few statistics on the passage we just completed. It took us 23 days 3 hours and 12 minutes to travel from Anse Amyot, Toau to Hilo, Hawaii. If we had been able to go directly, as in an airplane, it would have been 2195 miles. But this was impossible since there were some islands to go around, and we needed to follow a different route to ensure good wind. So our original plan was to sail a route of 2541 miles. How far we actually sailed is kind of a hard number to come at because each of our various tools (knot meter, GPS, navigation computer) have their own opinions of how far we had to go to sail those 2541 miles. But here's what the various opinions are:

The Navigation Computer says we went 2743 miles. This is error prone because the computer just adds up the distance between points that it lays down every 10 seconds. Sometimes the points, because of minor GPS errors, are farther apart than they should be. With almost 13000 points in the track from Toau to Hilo the errors add up.

The GPS says we went 2530 miles, but this is only adding up our day to day total mileages.

The knot meter says we went 2668 miles. I think this one is most accurate, though it's probably a little long.

So using the knot meter distance and our time we get an average speed of 4.8 knots.
