Default Pool/water tank rental for boat demos

The WRAM's are looking to rent a portable pool large enough to adequately demonstrate electric powered boats at the Feb, 2012 WRAM Show which will be held at the Meadowlands Expo Center in NJ.
Any leads or referrals would be sincerely appreciated.

If you need to build one, consider talking to Rob Wood of the Western Warship Combat Club. We've built a pond several years in a row for warship combat at Maker Faire in California and can give you some tips on building a portable pond.

This is UK experience, things might be different over there.  We used to do a show in the Blackpool Tower using the Circus arena, which could be flooded.  When we had a change of venue, we had the problem of finding a pool.  There were no suitable commercial items available for hire - we borrowed one from the Glasgow Richmond club.  A good size, but designed by shipbuilders and needed a 1.5 ton long wheelbase hightop Transit to carry all the bits.  We later borrowed a smaller one from a more local club, but had to provide a new liner.  The year after, the owner charged a commercial rate for use, and we started budgeting for building our own.
The plan was for panel sides, and to use a tarp for the liner.  Luckily, a trader came to the rescue and had one built.  Its now in its 7th year and still earning its keep.  The first year he was badly let down by the supplier of the neoprene pond liner, and had to use a tarp.  This leaked badly - it dumped about 15 tons of water over the exhibition hall floor during the overnight fill.  Since then, the neoprene liner has performed impeccably.  
Points to watch are - you need more than 6" of water if prop driven boats are to be used, props and liners must be kept apart.  
If paneled sides are used, the weight of water will try to shove them outward unless there is some strong strapping under the liner holding the sides in.  Not a problem outdoors on grass - very much a problem indoors on a smooth floor.
The size of the pond is determined by the size of liner available  - if the pool is 24 ft across with 12" sides, it needs at least 27 feet of liner.
2 cubic feet of water weighs about a hundredweight, 40 cubic feet about a ton.  
You need an escape route to get rid of the water after the show.  15 tons of water takes some shifting - best answer we got was a petrol driven pump until the water got shallow enough, then some brute force lifting the far edge of the liner until there was enough depth for the pump to continue.  Outdoors, dropping a panel while humming the Dam Busters Theme and getting ready to run works well.
Tarp or fabric liners are light and easy to handle but are fragile and prone to develop leaks easily.  The neoprene liner is tough, but is an absolute pig to drain, dry, fold and get into the back of the vehicle.
You need a willing mug volunteer to store it until the next time.
Some pictures of ours at the recent show here   http://www.modelboatmayhem.co.uk/for...topic=32392.50  on the second page.  (You will probably have to log in to see the pictures)
