Question about Exspecks video.

[Red Devil]

The only time in my life that I ever trout fished was when I was around twelve with my uncle around Galveston somewhere so I don't remember much. You guys make this trout fishin look funner than bass fishin. I'll be on Big Lake as soon as my better half let's me buy a boat. I just watched Exspecks youtube video and was wondering if there was a reason they were wadefishing instead of fishing out of the boat? It seemed like the water was deep enough for the boat. Was it so they could get low to the water so they wouldn't spook the fish? Just curious.
