I'd guess that makes the skis not want to grab a crease in the snow as well
as give structural rigidity to the ski... My composite skis are turned up
at the edges too.

Thanks for the observation, Noel. I'm gonna take all these ideas,
melt them in a big pot, and pour out something...don't know what, but
it'll be spectacular.
This will make the plywood lamination a bit trickier, but certainly
doable. I'm ordering some components for vacuum bagging, so learning
all these new skills will certainly delay the ribbon-cutting ceremony
(on the new skis) a bit. : )

I can think of more time on skis that I wanted to have directional control and the ability to yank hard back on the stick and sink that tail wheel in to stop, than I wanted more flotation. You can give it a little down to get the tail out of the snow... I ended not going to work due to mechanical issues with the charter 727 so I got to play on ski's today. I was very happy with them and the way she flew today. Got in 2.5 hrs in 0 degree temps and was nice and roasty in my snowmachine gear and the muffler heater.

Leonard,
Fantastic pictures !!! Makes me shiver looking at them. I sure love Alaska and really enjoyed Soldotna when I was passing through that area of the "Banana Belt" I just installed VG's on my model 4. It appears you have the same pointed ones that I do. I sure want to try them out but am waiting for my repacked chute from BRS to return so that I can finish off my annual. Do you notice any difference in your aircraft?

Leonard-
Are these skis the 13.5" x 60" skis? They don't look that wide, or
are you talking total width of the two skis as being 13.5''....each
being 6.75" wide?
If so, they don't look that narrow. But they look closer to 6.75"
than to 13.5" each.
Also, in the one picture, I see a runway marked with what looks like
"7S" ...is that for "snow"? (I'm gonna probably regret asking this
dumb question.) : )

The actual ski is 11.5" wide (each) and I made the 1/4" UHMW bottoms 1" wider all the way around hence the 13.5". In reality, with the way they turn up at the edges, I ended up with a width just over 13" (each).
They have been changing the runways out there and put in a gravel / ski strip this year for us outlaws that were always landing in the grass between the runway and taxi way. It was narrow and 3 or 4 times a summer someone would take out a runway light. They figured if they cant beat us then they should accommodate us lol. You want a challenge, try landing a cub with 31" bushwheels that have 2-3 psi in them on asphalt with a stiff crosswind....hence the need for the gravel runway.
I am not sure what they are thinking with the designation? 7 and 25 S may be short? it dang sure is not south..and in summer would not be Ski... Any normal thinking airport commission would have called 7 and 7L. Everyone just calls it 7 gravel and we all know what they are talking about.
Dick, I just put the VG's on yesterday morning. I screwed up and did not fly it on wheels before I went to skis for a fair comparison so I cant say if it is the VG's helping out or the ski's being less drag than those 24" tires. At any rate, I went up and ran the gamut yesterday and was happy with them / it.
First flight stall power off and clean was about 38. Full power she would break about 35. full flaps power off it was a gentle break at 32.
Yesterday power off clean 34, full power at 35 I was climbing at 400' minute, stalled at about 30 with a ridiculously high deck angle. Full flaps it would not break but just mush at 28.
Keep in mind that this was at 0 to -3 OAT. Initial flight and stall testing was done at 25 OAT.
