A Wind Vane for Ella

Ella is our sailboat, a 12 foot long hard chine skiff from the "Summer Breeze" plans that we built this spring. Ella has a “lug rig” sail, which is a setup that allows sailing fairly close to the wind, requires very little hardware, no complicated boom hinges, a lot of sail area for a fairly short unstayed mast. The problem is that there’s no good place to put a wind vane: Normally you’d either put “telltales” on the shrouds (the cables that hold up the mast) or a vane on the top of the mast, but the highest spar here is at an angle, held in place by the luff of the sail.

So I went into the shop to see what I could do. The brass was all assembled from K&S structural shapes, the only extra cool bit is that the top of the tube which forms the vane bearing has a plug with a brass wire sticking down to form a needle bearing. The gimbal assembly is cut out of purpleheart, I cut the ring with a hole saw and the center of the ring with a Forstner bit, in the drill press. The weight is a hunk of, I think Ipe, because damn it was heavy and seemed perfect to hold the whole thing in place.

In that second picture you can see the range of motion this thing gets.

And in the last picture you can see it up on the spar. This was in my back yard, we’re going over to camp at Lake Berryessa next weekend, hope to spend most of the weekend sailing in that northwestern arm, we’ll see how well it does.

Now that I do like

It would be great for my Hospice project.

It has a great look.

The problem with posting pictures of sailing is that my Canon G9 broke, so I’m back to using my cell phone. Which has a fixed focal length lens. Which is actually okay for a whole lot of things, but doesn’t work terribly well when the boat is only 12’ long… I end up with a lot of pictures like this:

But I’m hoping I can get some of my GPS issues worked out and we can do tracks of our path in Lake Berryessa. We’ve got reservations for a site at Chaparral Cove, and I’m hoping that northeastern finger is relatively protected and still sailable.

But, yeah, we’ll get the pictures we can…

Very cool. Have you ever got the urge to build a Sundial? I saw some neat ones in Jerome,Az and got a lot of info from the builder and may do one some time. It seems like something you would build too!!

Lake Berryessa…wow, I used to visit there when I was in the USNavy in the mid-’70s (Mare Island). It’s probably changed a bit from then. Not that I would necessarily remember, that was a long time ago.

Jim, I haven’t seen plans for a Sundial, is it something like a Sunfish/Sailfish? Flat closed hull? I sailed one of those when I was a kid that my uncle had built when he was a kid. We’re kind of more sedate and dryer than that these days, but… we really like the attention of unusual looking boats, and I got to thinking that we could probably park a trailer for a 16’ long boat if I parked on the street.

So if we did a relatively boxy hull (probably stick with a lee board), but put a fold out bowsprit and two masts on it, we could do something like a miniature version of the Scow Schooner Alma, large enough to take a few friends on, maybe even stretch out sleeping bags on a seat on, small enough that the two of us could handle, and enough lines and sails to really draw a crowd and get people pointing and talking.

The other thing I’ve considered is a two masted dynarig boat of the same scale: If we engineered it right, probably very easy for two people to manage, but definitely a “holy cow, what is that?” looker.

Dark_Lightning: I dunno, there ain’t a whole lot over that way, and most of it’s protected lands, it may be very similar to what you remember from the ‘70s…
