I've kinda sight fished from the bay boat. See a few fish and throw to them, throwing at wakes, etc... but most of my redfishing is blind casting. Same thing from the kayak. I just bout a 116qt rotomolded cooler that is 21 inches tall. The plan was to put it on the front of the boat for an elevated platform to do some true sight fishing. Most pre-fab casting platforms for your boat are either 18 or 30 inches so I'm on the low end. If you see those tower boats fishing the tournaments, those jokers are 6-10 feet in the air. I'm no geometry major so I'm curious just how much my line of sight will improve 21 inches elevated?
