What's the prejudice against inner tubes? I assembled a highly reliable
system for less than $15 bucks consisting of the following:

- Inner tube with damaged valve stem: Free from local tire store.
- Thu-hull connector (Vinyl pipe with threaded flange): $5 from local
marine supply.
- Brass water connections (garden hose repair kit): $4 from local hardware
store
- 25 feet of garden hose: $5 at garage sale
- Filling the glider and hot showers at the field to boot: Priceless

In all seriousness, the tube is highly rugged and portable - it rolls up to
fit inside my washing bucket. I've used it for about 8 seasons now with no
leaks. Depending on which of many sizes you select, you can get capacities
from about 10 gallons on up to ... enough to crush the roof of your car
(volume calculator he

underestimate the shower aspect either. The black tube sitting on the car
roof all day provides water at about 85 degrees F. This is just about the
perfect temperature for a warm shower on a summer day!

I also use a brass water-meter designed for measuring garden use. This is
expensive, but it allows you to be confident of your weight, especially
important at contests. The one I have came from... where else..

I Googled r.a.s and found posts about water beds, truck inner tubes and
collapsible plastic cubes from Wal-Mart. The plastic cubes will transport
50 gallons and fit inside my Jeep Grand Cherokee but nothing else will fit
and I don't want to unload the Jeep just for this chore. Full 10 gallon
water containers weigh more than 90 pounds and I don't like lifting that
much to pour it into the wing. I don't like water beds and inner tubes
either.

So, bright r.a.s people, how do you neatly and easily transport ballast
water to the glider if the gliderport doesn't have a tanker or water hoses
on the ramp? Once you get it there, how do you get it into the glider?
