Sun shade made of white tarp for boat

The sun is brutal!!  The air conditioner has trouble keeping up with the 95'ish outside temperatures.

So, we decided to make a sunshade from a 10'X20' white tarp....a little measuring and a little sewing.  Here is the result.  Kindof hard to see next to the white boat, but it's tied up over the cabin area of the boat. 

Keeps the boat 5-8 degrees cooler.  Worth the effort!
