What??? Bob Perry isn't running for president? Then what are we going to talk about in the Perry design rendezvous?

Back when I was in the Royal Navy, they foolishly let me play with a couple of their Nic 55s (sister to the one that won the first ever Whitbread). That was an amazing boat on almost any point of sail but I never saw anything less than 26 degrees; even then the sails were full but the speed was somewhat disappointing. We always reckoned on tacking through 80 degrees.

I think your friend has a very distant relationship with reality. My own boat, a fine Slipper 42 and a very good sailboat, would never get closer than 30 in ideal conditions.

I sailed an AC boat and I think it was something like (?) 30-ish. I can't remember the apparent though. Probably there is a calculator online to find out.

I like this post, makes me feel better about my sloppy sailing, and maybe it's more average than sloppy sailing.

My boat is a lot better going into it than I would have ever dreamed, and I don't realistically think I can haul any closer than like 35-40 with my mizzen and staysail only. I can whip them around as tight to the midline as possible while maintaining shape, but the speed becomes a third or half (depending on sea action) of what it would fifteen or twenty degrees off.

Granted, I'm a crusher, but I just don't see this fish story panning out.

Now that this thread is resurrected, I have a confession to make. After this thread I got on my boat and started to do some serious angle computing- it was then I saw my mistake. I can tack through 30 degrees ON MY GPS with a strong OUTGOING tide. The tidal current makes up a lot of the pointing ability that I thought was me. It acts like a vector taking me straight ahead. 35- 40 degrees is good for me in still water.
Now that I have had my humble pie, I will go back to behind the curtains....

That's ok Newt, the word apparent can cover all sorts of situations. Real or imagined

Haven't tried myself it but a mate of a mate was told of a sailor who glued his headsail telltales horizontally onto the headsail and was able to sail to 10 degrees away from true! True story! ;-)

I once knew a guy that could sail dead into the wind, Captain Havilah Hawkins from Camden ME had one about 25 years ago, he used a windmill to power the propeller, it wouldn't go fast into the wind but it do go foreward.

Juniper- did you see Waterworld? In the opening scenes the hero has a columnar windmill that is propelling the catamaran through the water.
Now if we put some solar in there too....

I do remember that scene, but Capt' Hawkins was real, I saw it in Rockland harbor in the late '80s early '90s, Hawkins was a 3 blade vertical, getting the gearing to prop right and wind mill to hull and blade picth all right at the same time is the hard part. I don't think it was the most effecent "sail" boat but if you needed to go straight up wind it can work, distance made good by windmill or tacking, my guess is tacking still would win, and then you have the cost side too,

Was it this?

I've read about this one too, never saw it as if I remember right he's down under in New Zealand or Austraila, looks like about the same idea, better hull, I think that one is a Gemmini without the rig

I've heard some talk about using a largish electric windmill to charge batteries then run electric motors, that is something I think will be functional very soon, not inexpensive soon, but doable, but it depends on what is expected from it, it will not be a diesel drop in, but if all you need is a hour or two at a time it should work,

I've thought about tring a hybred system, leave the Yanmar in place, add an Etek motor to the shaft by belt drive, then run it as a get off the dock power, and when the shaft is turning I can also charge the batteries from the shaft, then add windmill and solar,

The data I've got from Yanmar says my prop is using about 4 HP at 2000rpm on the engine, and at that I have a boat speed of about 5knots, two T105 golfcart batteries should run it for about an hour +-,

This is way down the project list so by the time it get close, LiFePO4 batteries may be in range,
