where do i buyor rent or become a distributor of an inflatable sasauge
shaped device that is placed under the keel of a boat then blown up
with air thus creating a V shape under the boat and lifting it up
about 12" off the ground and with several of these in place it is then
possible to move the boat by pulling with a large tractor to another
location. Also smaller bags are used to lift the boat up in order to
place the larger ones under the keel.  These rubber or synthetic
material about 1" thick and are circular like a sausage and are up to
about 5 to 8 ft in diameter when inflated with 15 to 20 PSI of air and
are as long as 30 ft Originally manufactured in Thialand. it takes as
many as five to move a boat 100 ft long weighing about 150 tons. I
would like to become a distributor for these devices direct from the
manufacturer.

Because of your mention of a V-shape, I believe the inflatable boat
lift that you're describing is the Air-Dock.

Request for Answer Clarification by acrane-ga on 18 Mar 2006 05:44 PST

sorry, but your research does not answer my question or fullfill my
need. i am searching for a inflatable unit that looks like a blimp
about 30 to 40 ft in length and inflates up to about 5 ft in diamiter.
 it is inserted under the keel of the boat leaving about 10 0r 20 ft
of the unit on each side of the boat (usually 3 or 4 units required
for a 100 ft long boat) and inflated to lift the boat off the ground
and then pulled by a large machine such as a bulldozer back into the
water.my purpose for these units are to return large boats,, that have
been washed ashore by heavy storms or high tidal waves, back into the
water. other uses of the unit in the past uring emergency conditions
was to fill them with water or fuel and tow them behind large boats to
where the products were needed. None of the answers to date meet my
needs. thank you
