[C38] death roll

[Bob Porter]

Hi Les;

The Pic was about 1/2 hour before, we were at about 8.5 K boat speed in 25 
to 30 k of wind. She was stable but we got hit by a wave and gust together.

The logo is from the train, Hiawatha, after which the boat is named. My Dad 
was a real railroad fan and it was the 1935 Hiawtah that lit his passion for 
railroads. As he was dying we talked and I told him my next boat would be 
named after him, Hiawatha.

As we head out to this season's races, I hope we do as well as we did in 
2005 w/o the excitement! (teh Chicago Mac is in its 100th running!)

Thanks

Bob Porter
