Frequently Asked Questions
Q. How fast can you go?
A. Several factors affect speed. Wind speed, size of the sailing area,
sail size, and dimensions of the landsailer. The small rigs we sail may
reach speeds of 40+ mph, although most of the time we are in the 30's.
It feels faster, since you are close to the ground. The landsailing world
speed record is 116.7 mph.
Q. Don't you have to sail the same direction as the wind is blowing?
How do you get back upwind?
A. The general course sailed is across the wind. If you sailed downwind,
the maximum speed would be limited to the true wind speed. The sail is
basically a wing standing on end. As air flows over it, lift is developed
to the downwind side. Since the wheels ( or runners on an iceboat ) resist
the sideways lift, it is converted to forward motion. Depending on the
sail, and wind speed it is possible to sail as close as 45 degrees into
the wind.
Q. How much do they cost?
A. A small landsailer can be built for about $200, if you are resourceful
in finding the materials. The most expensive parts are a good set of bearings,
wheels and tires.
Q. Do they have brakes?
A. No, although some have a parking brake. Brakes are pretty much useless
at speeds above walking. Turning into the wind is the most effective way
to stop.
Q. How much wind does it take?
A. Minimum wind of around 10 mph, for a small landsailer. In lighter winds,
a larger sail can be used.
