Particularly curious about how much wave-induced flex you notice in the plywood sides between the bulkheads and what effect, if any, this has - I'm guessing the aluminium guides to the sliding sections will help stiffen this up?

Here's several pics from paddling today at the base of the foothills (6,000ft elevation). The Falco tracked well, and turning was quick.Looking forward to your report Tom,
No side flex that I could detect. The Falco 16 should be completed tomorrow, unless I go skiingParticularly curious about how much wave-induced flex you notice in the plywood sides between the bulkheads and what effect,

Please do!Yostwerks wrote:I'll post pics.
I'll need to paddle both boats in all conditions before comparing them to my other designs.Does it perform better than the sonnet and than your older folding kayaks?
Epoxy ... I've been doing it this way for many years. The aluminum channel vs wood channel is thinner allowing for a smaller folded thickness.How do you attach the aluminium strips to the ply
Yes ... I'll be building the Falco Double next. It will be like the Falco 16 in length only. Width will be about 26" and there will beDo you think a 3-hole 16ft falco is feasible as use either as a single or double (with spare coamings covered )

Thanks for your comments. I plan to paddle the boat tomorrow or Monday.You should be very proud of this design/invention. It really is a beautiful looking boat for the cost to produce. I hope it's paddling performance meets your standards, and is available to build soon. I foresee this exceeding the sonnet in popularity among builders.
Thanks ! .... All black is a commonly used color with Greenland style kayaks. I've skinned several this way over the years.Hi Tom, I have to agree with the other posters and say the Falco 16 looks really smart in black- if Batman ever had to use a kayak, this would be it! (would suit a yellow bat logo on the bow!)
All Falco wood has been sealed , even that under the PVC. This is really no different than on a non folding wood SOF.I notice in the 16 the ply sides are not enclosed in fabric like they are in the Falco 12, are they treated with varnish
LOL !...or do you simply plan on not getting them wet?
Not an issue. I've paddled the Falco 12 several days and noticed nothing like you describe.I was also wondering whether the ply sections will try to slide together due to the induced rocker, and if a locking catch/block may be needed at each join to stop this and prevent creases in the skin? I only thought of this after seeing how some sof frames have a construction that stretches the skin.
I'm with you now. Feathercraft calls them stretcher bars. Initially I thought you were referring to side to side, not fore and aft. The Falco cross sections are hinged, and when they are opened, this creates side stress on the plywood frame panels which stretches the hull skin a bit ( side to sde).It was a mechanism on a folding open deck canoe, that was vertical handle that pushed the keel end plate out about an inch when you rotated the handle down. (in the same way a door handle rotates to move the latch in or out).
