[Sea Note]

I'm trying to decide which one was more expensive, boating or RVing in a Newell.

At least in the Newell I'm calculating miles per gallon instead of gallons per hour (70+ at 25mph cruise).  The real variable is time - we just ran displacement speed (9kts) from Key West to St. Pete (roughly 220 miles) with a generator running and burned roughly 250 gallons - on plane it's 12 hours dock to dock but I burn 900 gallons.  Then again, the boat doesn't ever need tires...
