Seems to be a bit of damage to the Islander's right wing, just outboard of the fuel tank sump!
I didn't notice that till you pointed it out stevef. The site where that pic comes from features several views of FXE including one in flight on a whale watching tour. The photos were all taken on the same day. I guess it may be an optical illusion, there are some puddles on the ground perhaps it is nothing more than a reflection.
Seeing as Mel hasn't even pretended his next one is easy I'm outta here!
