WOULD THE BOTTOM OF A WOODEN ROWBOAT REFLECT THE OCEAN CAUSTICS???

I am doing a really exciting split water piece and the bottom of my rowboat (over the mermaid in the vue-caustic filled water) is very dark... but seems to me that I have seen in real life caustic light pattern reflect or shine back on the boat bottom... is it the bottom under the water, if it would do this, or all the outside-under part of the boat above the water line??

I have a layer with each... so if anyone who knows could reply... I am hoping to finish and post this tonight...

Vue choked up and threatened to kill the scene after my mermaid and pirate in the boat were placed (and all the plants, my new caustic lighting)... when I tried to start populating the scene with little fish critters... so to save this scene I am now adding the critters in post... so will be doing that for a bit yet...

Thanks for any help! :)
