Winter time in Canada. I have a huge frozen lake in my front yard, so I might as well use it. I am putting snow skis on my mini. I will have to modify my mast step to accomodate my larger windsurfing sails as I will need considerable low end power to overcome the inital friction.
I changed the front end to make it a little shorter, I think this steering will work. The ski is a snowmobile ski skin made of plastic. There is a steel keel that runs on the bottom.
The back skis are some of my son's old skis before he became 6' 4". I am going to add a couple of braces. The skis are toed inward a few degrees.
Yo! Brian,
You may have to think about modifying the width of the rear Track of your machine for use in snow.. As you say you are going to need more Low End Power this in turn may decrease the side stability of your LY the same as High Winds do to a wheeled LY ie: More Falling Over? Give it some thought as you would know the sort of resistance given out by that surface.
Just a thought but go for it, sounds like it could be a bunch of fun..
Ron
PS; You have to get on top of water before the resistance drops..
please let this work
maybe slightly wider and laid over a bit at the back
how would I know
whats snow
Any Way, what would Sand Gropers know about Snow??????? Do they actually have anything better than Hills in WA???.
Billiard Tables should be so flat He He He!
Ron
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...
Great thing you are doing with your Mini Brian, putting skis on etc.
If what you are doing does not work out it is worth having a look at how blokart have set them up with ice blades.
There is no change to the rig or main frame of the yacht. They just unplug the wheels and plug in ice blades.
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.
I think Brian you should seriously look at an unaltered Windsurfer sail as they need the Low Down power to get them up and the high end to move quickly they have to make Compromises to cope with the Low End Drag. Perhaps that is the way for you to go. Big sails like you are talking about will only serve to put you on your side.. That is my problem with little LY's they are too small and unstable in High resistance situations even the Razor has it's problems in 40km winds with a large sail. Hey! That is in my experience, anyway. It seemed to me the faster I traveled the greater the Side ways slip developed.
Ron
PS; Cisco, the music in that clip was a Jews Harp was it not?? I have never heard one played like that before and certainly enjoyed it as well as the footage.
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!
OK! Thankfully I don't have you working in my mouth The lord only knows where experimentation would take you???
Any way Brian what and where are the wherefores of the Term Canuck?? Is it a general term for canadians or from a particular area?? detail would be good..
Ron
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.
brian,
How about a hover craft? put a 5 hp motor to raise it up and thengo like the wind...only kiddin... good try
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
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.
Ron
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.
