The following link goes to the original PakYak page hosted by Charles Hall, where the plans for my PakYak prototype have
been posted for many years: http://robroy.dyndns.info/pakyak/index.php
2013: I have a GoPro camera now, and have posted some videos on YouTube here:
July: I put a sail on the Dart: Here are some photos of the first trial.
The sail rig adds only 5 pounds to the 20 pound dart, and folds down to the same size.
2012: I recently got a video camera and made some videos of my Dart setup. They are on my Facebook page here: http://www.facebook.com/jim.heter
Here is a summer of 2008 photo of the original design (red) and the newer model (green). That's Richard Royce in the red one, and Devin Royce in the green one. [click on photos to enlarge them]
Over the 08-09 school year I got to assist a young fellow named Gage Wilkinson with a school shop project, because he wanted to build a PakYak and needed occasional advice. He ended up taking his project to the national Skills competition in Kansas City. Here's a link to his blog: http://indianapakyak.blogspot.com/
SEE BELOW FOR 2011 UPDATES about the new all-aluminum frame designs.
2009: photos of my new PakYak Dart and PakYak Sprint designs. These both have all-aluminum frames. The reason for the new designs was that I found that the aluminum tubing is almost 50% heavier than the Baltic birch I used for the wooden frames. But it is also a lot stronger. So I wanted to take advantage of that.
The shorter one, on the right, is the Dart, 10 feet long, folds in four 30 inch sections (pack on the right below).
The longer one is the Sprint, folds in five 30 inch sections (the other pack below).
The Dart is quicker and easier to set up. The frame stays in the skin when it folds. The Sprint takes a little longer because, although the frame is folded up inside the pack, the ends of the frame are pulled out of the ends of the skin. But with the cockpit in the middle section it is more even-keeled in the water.
Here are more pictures of the new boats:
This is the Sprint (top) and Dart on the shore of the Yamhill River in Sheridan.
Notice that with the one piece wrap-around skins there is no separate spray skirt.
And the bungee on the fore deck secures the paddle.
Here are pictures of the Sprint on the Salmon River north of Lincoln City, Oregon.
Above is a view of the Three Rocks just off shore. Right is the launch area at the end of Three Rocks Road. The paddle was only a mile or so round trip, but coming back was against both tide and current, so I got a workout!
UPDATE: January 2011
Photos of Dart, Sprint and Squirt.
I have begun selling plans and kits for the Dart and Sprint. Plans are $50, and include parts lists, cutting, drilling and assembly plans and skin pattern and instructions.
A kit consists of the special-order 1 X 1/2 inch aluminum tubing, cut in 30 inch lengths, and other aluminum pieces needed. At $1 per foot for the metal, kit costs add up to around $100 plus shipping.
I am asking $1000 to build a complete Dart and $1500 for a Sprint, but so far no takers. The price is negotiable.
All three of these boats fold in 30 inch sections. Here you can see a folded Dart beside three assembled boats.
I have built a six-section, 15-foot model that I tentatively call a Double or Tandem, although putting an adult in the forward position would seriously cramp the legroom of the person in the back. I'm not showing this model until I make some modifications to improve the assembly.
Here is a look at the basic frame construction. It is nearly all made from the 1 x 1/2 inch tubing, with some flat bar for spreaders and connectors. Most of the construction is a matter of drilling holes and inserting rivets.
The brace design ensures that only longitudinal members (stringers) touch the skin, so there is no interference with the streamlines of the hull due to water pressure.
Update: August 2011
I paddled the Squirt (mentioned above) around Ash Island on the Willamette River by Dundee in July, and decided it could use some upgrades. Here are shots of the modified frame with a diamond-shaped cockpit. The name Squirt still applies, but I've given it the alternate name of Scout, as it is especially suitable for youngsters.
Update: November 2011
Mike Runyon sent photos of his new PakYak Sprint, first float test.
The original PakYak online design (red above) weighs about 24 pounds. My aluminum version of that design (green above) weighs about 28
This is the Dart(left) and Sprint (right) with the skins open for a glimpse of the frames.
This photo shows the new Squirt (black) beside the Sprint and two Darts.
Here's another shot of the same group.
I also have in mind to build another six-section boat, but shorter so it will fold to about the 2-foot size of the original PakYak. But for quick and easy assembly the Dart is the best so far.
The photo on the left is me in my newest addition to the PakYak fleet, the 15-foot six section Tourist.
Here it is folded.
