You can probably steer them the same way you do a rudderless kayak.

Or at least as floatation devices. Kind of like a catamaran(sp?)

When these kids grow up:

We never had foam noodles to play with in the water! We had hard uncomfortable bamboo poles! And we liked it!

:cheerldr:

Meat curtain center board?

Maybe the pole is for balance. Perhaps they queve for propulsion.

(Extra points if you don't have to look up 'queve')
