Thanks, John, for adding to the knowledge base with real-world 
numbers. The Skookum obviously is a very slippery monohull. It's also 
somewhat smaller.

But your numbers do point out that, for trans-oceanic passagemaking, 
power catamarans don't offer as huge an advantage in performance as 
many people would expect. Power cats do of course have other 
compelling features, such as space, comfort, stability, shallow 
draft, etc.
