I am appreciated with your altitude towards fishing as you spend lot of time to prepare but you probably have 2.5 hours to enjoy fishing.6
To me, I spend 2 hours driving, 1 hr assembly and disassembly the kayak, 1.5 hrs cleaning the kayak, fishing gears and the car. Though I have about 3-4 hours on fishing, I am still very happy and enjoy the fishing plus kayaking/sailing.
