Spray rail. I owned the hull that's in the picture it's an extrmely wet boat even with those. Not sure if they're worth the effort.
I purchased mine in 2013 to charter out of. It's a super simple boat drafts nothing and will run with low horsepower. The only downside is they're totally flat in the back, with an extremely deep entry and stuff in turns and rough water. Doesn't really matter the conditions your going to get soaked. I had it for a year and sold it.
Trevor is a good dude. His boats are extremely affordable but not something you can beat the crap out of and expect it to hold up
