Thanks, Vance.

3' diameter steel ring (1/4" X about 2") with rods welded radially, each with a sort of rough hammered paddle on it. I had some pictures somewhere, but I don't have a clue where they might be now. I wonder what happened to that thing? Does anyone know or remember the kid who was helping George that last year or so? He was about 19 or 20, and I think George left him the tools and whatnot. Be good to track him down and ask about some of those leftovers. It would be a shame if all of it was scrapped out. Could do a little phoning around, I guess.

Vance,

Did you ever complete the sketch?  If not, are you able to do a rough drawing from memory?

You gotta love big slow turning props (says the Perry guy, of course). I was there the summer Capt. K got that thing working, but never saw it in the water. He'd been fiddling with the prop from way back when there was a yard of snow in the yard, and what you see in the vid is about the 3rd or 8th or 15th tweaked iteration to get it working with only a 10 speed bicycle crankset for a drive. Me, I was trying to get a sketch of the thing that I could then use to replicate the prop and run with a small motor (maybe 1 hp?). It wasn't balanced all that well as I recall, and it wasn't very pretty, but it surely did work a treat. He showed me this video to prove it. I thought the sail was a crazy idea, and that at his age, maybe George was getting a little crazy, himself. But it never stopped him, or even slow him down much that I ever saw, I don't know if he ever drew a print of the system or did more than just sketch the UEM components on the chalkboard as he worked them out. Pretty cool though, for something built more or less freehand. Like a lot of stuff he did. The Skipper was NOT afraid of hard work, that's for sure. I miss him, and the world is just a tiny bit dimmer without him in it. Those of us who knew him are lucky to have done so.

Alec, I was surprised too. 

The most power a cyclist can produce for short durations is around 1/4 HP.

I'm really shocked at the speed he was going, which appears to be on par with battery power! Bear in mind his age too.  

Best,

In the pile of stuff John Maynard sent to me was a DVD of Captain Kittredge taking out his human powered K250  for the first time.  Converted to MP4 and uploaded to YouTube, it might be the only known video on the web of the Captain.

Enjoy:
