2015 – By the Numbers

It turns out that 2015 was our shortest cruise yet of the five total cruises we’ve done to Alaska since we off loaded Alpenglow in January 2010.  Ignoring our “shakedown” cruise, we left on May 6 and returned on August 17, a trip length of 104 days.  The table below summarizes the easily tabulated values from the ship’s log.

Departure date	May 6
Return date	August 17
Duration	104 days
Distance traveled	3580.1 nautical miles
Total engine hours	629.2
Total genset hours	28.7
Number nights at anchor	67
Number nights at mooring buoy or float	7
Number nights at dock	29

With regards to average speed, I usually subtract the number of hours spent idling while fishing or sightseeing (i.e., time not underway), 42.4 hours in 2015, from the total engine hours and divide that value into the total distance traveled.  Using that method, we averaged 6.1 nm/hour.
