Iqyax Baidarka Research

I am currently working on the improved Bay Boat, that is, San Francisco Bay Boat.  The baidarka I had been paddling most frequently is about 20 years old, re-ribbed once and reskinned a number of times and a fairly close replica of an Atka baidarka.  This particular boat just got a paint job.  The old paint job consisted of a varnish base covered some time later by a color coat.  The color coat was peeling badly, probably because I never sanded the base coat before putting on the color coat.  The re-paint is done now.

 

The baidarka is on the left with its new coat of gray latex house paint.  I store my boats outside so the most critical job of the paint is to keep the UV rays from degrading the nylon skin.  Opaque paint does a good job of that and more cheaply than exterior varnish.  Thats my King Islander to the right of the baidarka.

The only drawback of the old baidarka is its narrow width and fairly deep hull which makes it a challenge to keep upright.  Its actually not that bad once you get used to it, but its not a boat that you can just sit in and relax.  When youre not moving, you need to brace or have the paddle out as an outrigger.  

So, enter a wider version of the Atka iqyax^.  The idea behind this boat is sufficient width to allow lounging without constant bracing but not enough width to make it slow, a boat suited for longer stays on the water, like a bay crossing, about a one hour affair.

Inside view of the hull.  Good width and flat rib profile to make the boat stable. 

And an outside view of the hull with the stringers temporarily taped and lashed in place.  Also note the open jawed bow, a configuration I have been playing with, mostly because this configuration makes it easier to align the keelson with the bow assembly.

Also the upturned nose of the other bow configuration is more prone to breaking because the grain runs across the upturned part instead of in line with it.

Finally got the center support glued down

Last night, I finally got the center support for the rear thwart glued to the keel with thickened epoxy.

The delay was caused by a slight change in course in the way Im trying to straighten out the bend in the plywood seat. I had removed the seat & was prepared to epoxy four 15" reinforcing pieces to the bottom, hoping that would keep the seat "flat." However, the warp seemed minor enough that the only way to keep it flat this way would be to run full-width reinforcing strips. I cant do that, due to the center support.

So, the change in course was to clamp levels to the plywood, to keep it flat. THEN, after trimming the sides to fit, Id attach the side blocking. In theory, once the blocking is in place at that "level," it should force the seat to stay flat once its attached. Thats the theory, anyway.

Center support, finally glued down.

This is my effort to keep the plywood flat until the side blocking is attached.

I used the extraneous epoxy squeezed out from the seat support to fill in imperfections like this in the plywood.

The structural part of the thwart is basic A-C grade exterior plywood from Home Depot. A little tip-of-the-hat to William Jackson here...

Heres where I had marked the sides of the hull for measuring the seat support dimensions.

Im still undecided on whether to install a drain tube, or to just use a bilge pump. If I do install a drain tube, this is where the hole will be drilled.

Fire as an Alternative to TV

I dont want to make too much of the making of and sitting by campfires mainly because it is something that most people who go camping have probably experienced for themselves,and that sitting by a good camp fire is vastly superior to watching TV.  Still, it is something that needs to be said. And I have some theories about why a campfire is better than TV and I will share them with you.  Feel free to disagree.
First of all, the obvious - fire is entertaining in and of itself.  There is drama in a fire.  One knows the plot well enough but never the details.  Wood, at first reluctant to burn for a variety of reasons like wind, lack of kindling, moisture, etc. eventually is made to burn.  Then the fire burns, produces coals and maintenance of the fire becomes easy, one simply throws more wood on the fire and at some point becomes tired of the process and lets the fire die for lack of fuel or actively snuffs it out.  This is the plot of the entertainment known as fire. And there are many variations on it.
The primary reason I prefer fire over TV is that fire has no political or social agenda.  It does what it does. It burns according to various basic rules and thus is educational about the laws of thermodynamics.  Not that looking at fires is what inspired thermodynamicists to come up with their theories, but looking at fires does give one a sense of how fire works and that in itself may give rise to many useful metaphors.  TV on the other hand is almost entirely agenda driven.  Someone is selling you something constantly, obviously through commercials but also in the content that the commercials enable.  Implicit in all story telling is a viewpoint, a lesson, a moral.  Even if nothing obviously new is being communicated, the very fact that the TV portrays some activity is some kind of endorsement for it or a polemic against it.  If you dont agree with the lifestyle choices of the people portrayed on TV then TV watching is a chore.  So fire, much better.
Finally, sitting by a fire with other people is a social affair and as such, becomes a lab experiment in social dynamics.  For one thing, the progress of the fire needs to be managed and as someone once famously said, no two people can ever agree on the right way to poke a fire.  If more than one person wants to manage the fire, a struggle invariably ensues, covertly or overtly.  Words will be said about the management of the fire and a winner in the struggle will emerge.
Enough for now, I have found that the internet has lots of campfire pictures.  I will comment on some of them in future posts since the pictures raise specific points such as preferred ways to arrange the logs, what to wear to a campfire, safety issues around the campfire, what to talk about at a campfire, how to cook on a campfire and more.

Eastern Arctic Kayak Construction Interlude

Yesterday I blocked in the keelson on  the inverted deck of the kayak in preparation for installing the ribs.  I am now at a crossroads where there are a number of ways to construct the ribs.  Not knowing exactly what the shape of the bottom of the kayak should be since I have never built this type of kayak before, I have to come up with a way to do this.  I can think of any number of ways to proceed but would like to go with the aboriginal scheme of shaping the ribs, whatever that is. 
Zimmerly is of no help here. His article in Sea Kayaker gives you the exact dimensions to cut the ribs to.  This only works if you also shaped the deck exactly like he instructed.  Since my deck is not shaped like his, his dimensions will do me no good.
I could do the ribs the way I normally do them, that is, steam bend them which would produce rounded chines and a slightly rounded bottom, but I want to go for the flat bottom and hard bends in the ribs approach that is more common for the EA kayak.  I guess I will just have to experiment and see what happens.
