Re: Circumnavigation without instruments

Another ghost thread resurfaces.
I'd never heard of this guy until just now. Personally, I don't see the big deal. The Polynesians repeatedly found tiny islands, not huge continents, without any instruments at all.
Trying to prove what is already a known fact seems a bit out there to me. But hey, what do I know? I had a sextant, a couple of stopwatches, a few books, a compass, a taffrail log and a chronometer when I circumnavigated.

An example of them is that when he got south of Australia he suddenly turns left and sails straight up to a landfall. This after sailing for at least a month, probably more, completely out of sight of land. I wonder what it was that let him believe that by turning left he was in line with a port on the Australian coast. Remember the claim that he had "an hour glass as his only navigation instrument "

The course that is shown on the chart actually could not have been done better with all the instruments that modern science can muster. Many of the single handed racers that have the best instrumentation and comms that money can buy would be proud of sailing a course this good.

I'm not yet convinced.
The hour glass was used just to keep fair, the amount of time each person was on watch, period.
As to the Left turn that brought Marv into the port in Australia, it was a dead North turn. He is a
celestial, solar, wind, water current, etc, navigator. The sun comes up in the East, so he turns Left
hence North to head to Oz. How did he know when? Maybe Last night he had the stars to look
at and he knew where he was on the surface and decided he wanted to go further east, but maybe
not a full 24 hours worth of nau-tical miles. So, next day at high noon they made the north turn.
The man made this voyage to prove the ancients could navigate all over the salt water limitlessly. I'd
love to repeat his journey.

Re: Circumnavigation without instruments

To all the detractors keep in mind that when he did it there was no GPS for civilians, SATNAV was rare and LORAN was not worldwide.

So when he did it without a compass or a sextant he was not giving up all the geewhiz stuff that we have today.

The compass and the sextant would have been his backup unless he had the money for an expensive SATNAV.

Hard not to see what an amazing accomplishment it was.

I wonder how many who are knocking this guy have gone offshore even for just a couple of thousand miles with just a sextant, watch and compass? If you haven’t then maybe you can’t appreciate what he did without even those.

I was intrigued by:

Do you mean the Pleiades? Why would they be always in the East? Makes no sense to me. Care to explain?

The only stars I would expect to be in a constant direction is Polaris and the Southern Cross (kind of).

(I was also impressed by you knowing Thor Heyerdahl's family. Way cool!)

Re: Circumnavigation without instruments

I may be a pretty new sailor, but I am not at all new to DR thanks to the USMC Coxswain's Course and have nothing but respect for this guy. I like to minimize my use of my GPS when I am out on the water or in the woods, using it and it's precious battery life as a backup to my "analog" compass and course.

Haters gonna hate.

All if this criticism strikes me as blatant ageism.

Re: Circumnavigation without instruments

I would argue that no person reading these entries could do what Marvin Creamer did on Saturday. At 97 years of age, he kept a crowd of people spellbound with his detailed narration of a voyage he made in '82-'84 -- without notes or a teleprompter! I have known Marvin for years and never cease to be amazed! Ralph Harvey, still webmaster of, but the site is being transferred to Rowan U.

Well, if you ever do, given that you'll be adequately prepared, be sure to let me know you're coming and I'll show you around!...
