This LEGO set #4012 "Wave Cops", actually floats.  You can play with it in the tub, or in the back-yard pool.   It comes with (2) mini- figurines in their police gear and wearing baseball caps and life preservers.

The boat looks like a high speed pursuit patrol boat guarding the sea-lanes and harbors.  This kit is 100% complete and it a lot of fun to build.  Being a retired set, it is all the more in-demand for your serious LEGO collectors.

#4012 Wave Cops is available for only $39.95, plus a small nominal shipping charge of $8.00  that includes insurance against loss.
