Go.....for it Saby....we are all a bit jelouse

please let this work
maybe slightly wider and laid over a bit at the back
how would I know
whats snow

I thought wider track as well but surely a Canuck would know better than me
about these things

Spoken like a true Tasmanian.

I always thought Tassy could be the largest state in the country
(well....it would be if they flattened out all the hills)

If the skis were laid over, the outside bottom edge would sit higher than the inside bottom edge. Since craft straight line stability will come from this outside bottom edge would think flat or maybe slightly laid under would ensure a good edge, laid over would have a good edge when one ski is lifted. Gut is telling me slightly under unloaded so when you load axle skis are flat or laid under just a bit so you always have an edge biting.

go get em Brian...I wonder if they had a knuckle on them so they stay flat?
on another subject.. Any of you guys throw the boomerang?was in my garage and saw my old quiver of rangs... Little trivia/? Can you name the 1976 Us National boomerang champion????I will take my bow now..... been so long ago i forgot...
Was held In Washington DC...

You are multitalented I had a go at making and throwing those things but never reallygot to grips with them There is more to them than what appears is about the only thing I found out Perhaps you can give us the secret

start with a large bent branch of hardwood, nice and heavy, split it down the middle to make a lefty and a righty.
then plane it down to make your boomerang, it should be flat on the bottom , and have a chord that is max at 50%.
make it thin , hence the heavy wood. you want limbs of 350mm at least.
i should warn you this design is supposed to fly low and level and break the legs or neck of the hunted prey, so dont throw it to or at another person, unless you are trying to bring em down and hurt them.. those spinny, comey back thinks are for hunting flocks of birds like ducks or parrots at waterholes



hers a small hunting one for duck at a waterhole, user camps nearby , makes a load of quicky rough boomerangs, get up early ,catch ducks ,cook ,eat, move on ,leave boomearangs lying around camp or wherever they fell ,as its lighter to make new ones at next waterhole than lug them around.
this one would have been lost in the mulga when the walkabout vehicle of choice was early Ford falcons, maybe WB holdens

I would love to be able to put skate blades on my rig. The friction on the blades is considerably less than that off snow. Unfortunately, we don't get enough consistent wind to blow the snow off the lake. The initial force required to get the skis moving is my biggest problem (so far anyway). I have skis for my zooter that I tried last winter, with the 5.5m sail in a 18km wind, I could not move. I attribute a lot of this to the steel runner under the snowmobile ski skin. I think once I am moving, it will be a lot like getting a windsurfer up on plane.

For my LLFM I used regular skis on the back to reduce the drag. I used the snowmobile ski on the front to aid in steering. I think the 5 degree cant of the skis in the back will be sufficient to aid in tracking. I have the skis in the back out the same distance as the wheels on the mini.

It looks like the front ski should be okay for turning, but the turn radius will be large.

There is supposed to be 16km winds tomorrow so I hope to take it out and see. Possibly an 8 or an 11m sail. It will work or something will break, hopefully not bones.

The plan is to use my windsurfing rigs. I have a quiver of Sailworks Retro's, 5, 6.5, 8.0 and 11.0. . I can rig all the sails then easily switch from one to the other as I test it out. We generally don't have much wind here and the air is a little thinner at 2500 ft. Most days we are lucky to get 15km/hr. A great day would be 25kph. I need the low end power to get going once under way I should be smoking. If I find I am tipping over, I may have to drag out my old mistral one design from years ago. I will just have to experiment.

I am all done and am just waiting for wind. The forecast has been for wind, then they change it. No wind forecast for the next week....crap.

Seeing how everyone is having so much fun with the ALSA, I think I should start my own ALSA(Alberta Land Sailing Association.). It will be much easier since I am the only Albertan I know of who has a land yacht. You guys don't realize how good you have it. You have great venues, predictable winds and mates to sail and socialize with. CAUTION...don't screw it up!

Well, that sucked. We had about 25km winds, and the craft did not move. We did manage to break a ski as we pushed the empty llfm over a snow bank. I don't think the ski thing is going to work. We tried the wheels as we only have a bit of snow, but the amount was enough to keep us from moving forward,just to make us really happy the snow would also hit the frame causing a braking action. Some pretty cool spins when I pushed Mike to a patch of clear ice.

I made a rig to put a really big sail on, however, at the cost of a windsurfing rig, I decided not to risk damaging it. I think we would just tip over anyways.

I have two more ski skins to try those as back skis, but these, like the front, offer a lot more initial resistance. If we get a really good wind I might give it a go, but for now, I think this will be "one of those good ideas.

Will just have to wait for spring.

Nothing ventured nothing gained... bet you've gained some great ideas for next winter Despite the complaints and the country grinding to a halt over here, we never really get consistent cold and snow to do anything and the ice on the local lake is less than an inch thick (25mm). Any mileage in going big on the skis like a snowboard so you're sitting more on top of the snow??

Cheers Col

Maybe steel runners like the old Flexible Flyers.

Somebody figured it out. Bigger sail, a way to hike out. Hmmm

OK! Brian,
I would suggest your Land Yacht Sail wouldn't be satisfactory for Snow.. Like Water there is a High Resistance to get you moving therefore you would need a sail with a great deal more shape. I think you should be looking for a Wind Surfer Sail or even develop one with a lot more Cord/Air Foil Shape.

PS; The reason you broke the Ski is that they are fixed mount. They should be Pivoted so they can move with the terrain. Perhaps you should try pairing skis on either side with a slight tilt giving a concave control surface/Keel effect.
