19' 9" Chaa Creek Expedition
Re: 19' 9" Chaa Creek Expedition
I have shifted my focus temporarily from the canoe to making a new hammock/UnderQuilt/Tarp for this season ... but I will try and get out tot he shop today and see if I can take a few pics of where I am going with the portage thwart.

laminated thwart experiment ... turned out quite strong and lightweight ... will be shaped more later

Re: 19' 9" Chaa Creek Expedition
any other ideas for all wood portage yokes?
Re: 19' 9" Chaa Creek Expedition
I am still redoing all my camping gear and i don't have any pics of what I am planning for the current build, there has been a progression of yoke designs for my boats, I am applying everything I learned on this last one.
You may consider the following points .... they are just what I am using for the design and based on what I have learned so far ... I am using cherry trim, so assume hardwood = cherry, but truthfully most other hardwoods will be about the same
- 2 pieces of hardwood 1/2" x 3/4" is enough to support the weight of an average canoe (~40-50#s) for a yoke
- making the dish from hardwood costs a lot of weight and does not really contribute to the purpose of carrying the load of the canoe
If 2 pieces of hardwood (sized as above) were shaped (to flare at the gunnels) and were connected to a light softwood dish (say white cedar) through the center, remember the dish part only needs to slightly less than your shoulder width, it does not need to go to the gunnels .... I believe a significant amount of weight would be saved. In the process I believe a really cool looking yoke could be created. I intend to do just that for my solo, using hidden hardware to easily install and remove as required.

Re: 19' 9" Chaa Creek Expedition
now that is getting interesting... can you elaborate on the "dish" idea though?

Re: 19' 9" Chaa Creek Expedition
gluing up some more laminate components... 3 ply, 1/4 maple laminate turns out to be super strong with a slight amount of spring under a lot of pressure

Hi Jim,
This is a photo of the NWC dish I made to replace the typical big foam blocks, on my solo yoke, that attaches to the seat. This dish only weighs in at a few ounces, much lighter than foam blocks or a hardwood dish.
The idea is to use that sort of lightweight dish, and just put a couple of hardwood rails side to side to carry the actual load, while the dish makes for a comfy carry. The actual rails could be solid pieces or laminated 1/4" pieces, shaped to give flair and maybe please your eye for shape. You may need to go a bit thinner if you want to bend very much (or use steam at 1/4"). Anyway, I am a few days from getting back to the shop and starting mine.

Sorry, Brian, but the pic is not coming up.
Keep your paddle wet and your seat dry!
