Probably my weirdest request ever...

I'm looking for an old picture of someone's idea of a wind powered boat using a screw propellor. Basically, it's a boat hull that has a long shaft running from the screw prop underwater to a huge canvas windmill type prop mounted on the same shaft on deck. When wind turns the big windmill, it delivers power to the underwater prop directly. No gears, no neutral, no reverse. This pic is just for demonstration but I'm having a hard time finding it. Wondering if anyone has ever scene this handsketch before?

:D :D This is one of the sites I was looking for. Thanks alot, i really appreciate it. However, there is one specific picture I'm looking for which looks very old, maybe from the early 1900's.

Also see Rig 100 in Bolger's book 103 Sailing Rigs.

maa. melee, the Bainbridge Redwing. A two blade propeller on a Redwing. The British boat Redwing not the US Redwing.

The boat appeared on the TV programme called Wind Driven on the Discovery's H&L Channel (a few years ago). H&L is now called Discovery 'Real Time'.

There was an article in WoodenBoat quite a few years ago about a windmill boat built by Havilah Hawkins in Camden, it would sail directly to windward. He was one of the original Windjammer captains and to say he was a character does not do him justice.

A search in the magazine section should get you something, or perhaps one of the Camden locals who frequent this place could help.
