As long as you are always in the back, that could pass as entertainment.

Re: 19' 9" Chaa Creek Expedition
wondering if i should hang the seats from the gunnels or mount on the hull
Re: 19' 9" Chaa Creek Expedition
Either way is fine. I've always hung mine. If for some reason I want to change the height, it's easier.jimlgordon wrote:wondering if i should hang the seats from the gunnels or mount on the hull
You might be able to save some weight by mounting the seats to blocks epoxied to the inside of the hull. That way you could minimalise the size of the inwhales.

Keep your paddle wet and your seat dry!
Re: 19' 9" Chaa Creek Expedition
On my current build I am doing just what Jim stated. Minimizing the gunnels and using cleats on the side.
I am fitting the cleats (cherry) now, so I will share a few thoughts on the process:
- you need to shape the hull side a bit, as I don't believe there is a flat spot anywhere on a hull
- set the cleat as low as you think you will ever want the seat, you can always add a spacer to raise the seat
- plan to shape the cleat block to save weight, I reduced my cleat weight by 30% just sculpting it
- I used 3/4" x 2" x 16" cleat block with an additional 3" x 2" blocks where the seat rails are ... it's nice to have a bit of leeway where the seats actually mount
- rather than thru bolts, I plan on using helicoils in the cleat ... you drill and tap the wood, saturate the hole with epoxy, remove excess and screw in the insert, very strong and avoids trying to get a bolt through the entire cleat

Hey ... that looks the exact carpet I have on my canoe rack.

Re: 19' 9" Chaa Creek Expedition
I started cutting strips to steam and laminate for seat parts. This canoe is a three seater. I am trying to figure out how to make the middle seat removable and interchangeable with a portage yoke. Maybe big bolts and wing nuts will work for that.
Re: 19' 9" Chaa Creek Expedition
If you cleat mount that middle seat, you could use a Hela coil in the cleat, then a short bolt with a small knurled handle to fasten the seat in place.
Use another hela coil in the gunnel to hold the yoke in place, when you portage you take the seat bolt out, remove the seat and just install the yoke with the seat bolts. It could also work just using dedicated bolts for each.
The Hela coils open a whole new set of installation options for these types of builds. On my seat post that you commented on, if you look at the mounted seat pics, you will notice that the bolts don't show on the gunnels. There is a hela coil installed underneath the gunnel and the bolts screw in from the bottom, so nothing shows (hidden hardware). This will be the 5th year on the water for that boat and I am calling the hidden hardware a success.
If you are interested this is the source I started with: http://www.greenval.com/FAQhidden.html
I have progressed a bit since then, but fundamentally, this explains it.

Re: 19' 9" Chaa Creek Expedition
Here's another approach for a solo yoke that doubles as a backrest. Weighs almost nothing
It accommodates a movable seat while maintaining exact balance point for the yoke. Converts between backrest and yoke in about 30 seconds.

Re: 19' 9" Chaa Creek Expedition
I am sure they work very nice but big, black foam pads are not the look I am going for :-). The hela coils sound very interesting. Most of our paddling involves saltwater so we have to ensure all hardware is for marine use.
