Hi Gang,

The program that John is referring to is called SAS.Planet and is windows only.  It allows one to download map tiles at various zoom levels from many, many sources on the web and save them to a cache on your hard drive.   That means you can essentially have Google maps, Google satellite views, and Navionic charts onboard and in use even when not connected to the internet.  Those are the three I am playing with.  Oh, I guess I've downloaded some C-map imagery also.

The program lets you export user-selected polygons of stitched map tiles into an image file, such as JPG, which can be viewed in various graphics programs.  Because it also saves a .kml file of the image coordinates, one can run that info through a separate program called "imgkap" and end up with a geo-registered KAP file, ready for using in OpenCPN.

SAS.Planet can also be used as a chartplotter.  I've connected my handheld Garmin GPSmap78 to my laptop through a USB cable, and tracked my movements in real time, while recording that data to a file.  You can add waypoints as you go.  If Dan had this running on his visit to Gibson Island, we would all know where he was when that picture of him was taken.  :-)

I've also connected an Android device to a laptop using Bluetooth and sent the Android's GPS info over to SAS.Planet and OpenCPN.

Speaking of Android devices, there are a couple of apps that I have used for mapping.  "Backcountry Navigator" and "US Topo Maps Free" both download map tiles similar to SAS.Planet and allow you to view them offline.  You can track yourself on the map and record that track to the device.  

Now that I think about it, this sounds like what I would have talked about at our cancelled electronics workshop last year.  :-)

Yes, John, I am hoping to come down to Fern Ridge.  I am staying away from any chainsaws I hear in my neighborhood, so as not to be tempted to scrounge new woodturning stock and screw up my back again.  If I can finish slopping the paint on MoonlitTurtle, I may come overnight.  Otherwise, I will try for Saturday.

Fern Ridge Charting, and Lunch Messabout? (was: Thanks John, great pix of the mudhole ----- Surprise Status)

How's that coming Mark? I hope he comes to the Spring Messabout to tell us about the project.

The small-scale Navionics screenshot I uploaded to the Coots site is just an overview. I can do some larger scale shots of portions of the lake and put them there for reference. I could even calibrate them in Ozi and turn them into raster charts... But the accuracy of Navionics bathymetric data is doubtful. If they show a channel somewhere it's probably around there. Useful. If you draw four feet and Navionics shows 5 feet somewhere, go slow, watch your depth finder, and have the push pole handy. ;o)

Thursday would be a good day for another Fern Ridge lunch messabout. The traditional Coot lunch day, and if I stay late I can watch the racers in the evening. :o)

Depth finders for small craft

Electri-Cal
 

The easiest way I found is getting a e-Bay ice fishing depth finder.  I got mine in great condition from a guy who didn't want to freeze alone in the dark, on a cracking ice sheet anymore.  Geee! what a surprise, a Hummingbird brand, shipped from Michigan, not much use and has a case, sensor and everything.  Think I paid $50 to 60. bucks delivered --- before covid of course. 

Now I did change it to wired in, later, and I does everything I need.  The case used two 6 volt lantern batteries, some use d or c cells wired, but all are actually 12 volt,  So, you could just buy a regular one and build a 12 volt power supply, with the reading part on top, like a built in model.  I bought my H-bird, because I had one before and it worked great, depth alarm, shallow alarm, water temp on some, the stuff you need to know at a reasonable price, since it's older equipment.  

A great addition for safety, my opinion anyhow, ----  Cal           PS -------  Logs, rocks, and shallow water are really a map thing or local knowledge, sail in the deep part, row the shallows.  Earl showed me that last week end !!

The new dash is built, I have wires pretty well figured out, but I will do that after the new instruments come in, the water (like tide and tide ) wait for no coot.  I plan to be back with several good coats by wednesday, since I went for fast dry urethane this time.  I don't like it as well as the heavier helmsman, but it does go on wetter, and dries like water base as usual.  I spread each set of wires out in a fan, with the instrument still attached.  All I need to do, with holes prepared is to pop each one back in as its assembled,  This is my third dash build on one boat, so the old dash is a good start to fitting.  Easier to see layout, slightly bigger area design wise, so room for more without as much panic.

Maybe about Wed., or Thurs. I'll be ready to go  see ya, ----   Cal 


Re: Fern Ridge Depths (was: Darn Burgee Escaped over the Winter)

 

I think you may have been standing on what's left of Royal Avenue, which used to cross the lake to Elmira (and was probably named "Elmira Road" then). If so, you were taking a bath where I've driven my car in the winter, long, long ago, when the pavement hadn't all washed away and there wasn't a gate across the road. <g> There aren't any natural piles of rock in Fern Ridge, just that one big glacial erratic boulder out there somewhere. Navionics shoulda shown the old road, as it sticks up a ways from the mud. They also don't show thew low dams, 4' below full lake level, the Corps put in several years ago to retain water behind Gibson island in the winter for waterfowl. They're probably just awash now. They also show only Docks A-D at Richardson. The "new" docks A-D and the "new" E Dock. were put in years ago.

Navionics is useful on inland waters, but take what they show with a grain of salt. "trust but verify!. <g>

Re: Wooden Sailboat for Coos Bay?

 

The boats are one and the same. Some of us Coots visited Ted Chism at his place just up Joe Ney Slough from the Charleston boatyard in February of 2008. I saw the drawing from the Smithsonian he used to make the plans for the boat, and we loaned him American Sailing Craft so he could read what Chapelle had to say about the boat.

https://flic.kr/p/2kXo2QL

https://flic.kr/p/2kXx4oL

https://flic.kr/p/2kXo2Mj

There weren't any offsets of construction drawing from the Smithy, just a full size version of the illustration in the book (Ted had never seen the book, he just ordered some drawings of likely sounding boats from the museum and chose the flattie). He made his own offset table by measuring the drawing, and worked out the construction from Chapelle drawings of similar boats. I think he said he was going to put skipjack-like head on the bow, and maybe he said he was going to use a gaff main. It was a long time ago... And we still haven't got the book back! ;o)

It was indeed low tide when I took the photo of the flattie on the mud. Ted knew he needed a boat that could dry out because there's not much water in Joe Ney Slough during spring low tides, or even neaps. <g>

A sharpie wouldn't be so fat, though you can't really tell much from and end-on telephoto shot. The old-time builders discovered that a fat flat-bottom boat sailed better if you gave the bottom some V aft.

when he was still putting the bottom on, years ago... Launched in 2017.

Fern Ridge Depths (was: Darn Burgee Escaped over the Winter)

 

Ow! Those four-bladed props are expen$ive! :o(

Here's a screen capture of a Navionics chart for Fern Ridge, with the water depth adjusted to 4' low, the current condition. The light blue shading is 6' of water or less, the darker blue with dots is 3' or less.

http://www.coots.org/MapImages/ValleyLakes/FernRidgeMinusFourFeet.jpg

I have no idea how Navionics gets its bathymetric data, so at this scale consider this just a general approximation (there's more than four feet around the Richardson marina), and if you use Navionics, at larger scales. "trust, but verify". <g> But you can see that there's still plenty of lake for little boats to sail in, and even the Big Boys with 4' or more draft, though their lake gets smaller.

The attachment is Mike Stanley's Pearson Packet out Wednesday evening. He plays a concertina too! ;o)

Re: Darn Burgee Escaped over the Winter

 

Though Fern Ridge is 4' below full, there's still plenty of it where a 3' draft boat can sail. Just be careful around the edges. If you touch bottom just pull the daggerboard up a bit. One of the 5.5s put in the other day, and it draws 4' 4" or so, and can't pull its keel up. <g> The Santana 20s draw 4'.

Cal's right that a depth sounder can be handy on a shallow lake, even in a little boat. The cheapest way to go would be a fish finder, even though you'd need a 12 volt battery to power it.

Wait a minute! Portable fish finders have got cheaper since the last time I looked (a few years ago). Anybody tried something like these? A Coot can probably cobble together a hull mount for the floating transducer.

Houses, are but badly built boats so firmly aground that you cannot think of moving them. They are definitely inferior things, belonging to the vegetable not the animal world, rooted and stationary, incapable of gay transition. I admit, doubtfully, as exceptions, snail-shells and caravans. The desire to build a house is the tired wish of a man content thenceforward with a single anchorage. The desire to build a boat is the desire of youth, unwilling yet to accept the idea of a final resting-place. (Arthur Ransome)

Re: A Sensible Outboard Cruising Boat?

 

Back in the day, an experienced boatbuilder could knock out a bent frame carvel planked small boat in no time. That's why there were so many of them. <g> It'd be fun to build one today, but they really aren't practical anymore, since they don't take well to trailering. And we aren't experienced carvel boatbuilders. <g>

Cal tried something interesting when he built the boat before Surprise he mentioned. He made the sides by lapping the strakes together first, gluing them into single panels on the workshop floor. Bending them around the forms must have been harder, but the result was a good-looking boat:
