Pontoon boats and other flotation devices . . .

[rderedfield]

I fished Lenice on Saturday until I had to leave just before noon.  At that time, my partner and I counted about 50 different flotation devices (tubes, etc.) out on the water!   I noticed that probably 1/2 of the craft were float tubes, most of the other 1/2 were pontoon boats, and there were a few prams and rafts.  I'm not sure how to quality the Watermaster and Abel craft/rafts, but there were a few of those, too.   Anyway, I'm curious what y'all use as flotation devices for fishing lakes?  Or rivers?   Richard
