So funny about the power loading - I don't do it, but I've had a few people chastise me for not powerloading at our local lake. We load/unload at a four lane ramp with two courtesy docks. From the time we pull up to the dock to the time I have the trailer backed down, the boat hooked up and the whole rig back up the ramp, I'm occupying the takeout area for 5 minutes, max. With rare exception, from what I've seen at our lake, the folks who nose up to the dock, drop a driver, float back out, wait for the trailer to come back down to the water, idle a couple hundred yards back to the dock, power load, hook up and go are actually tying up the ramp for just as long if not longer (their boat may not be in the slot at the ramp, but it is not useable by anybody else, just the same).
Seems to me that everybody needs to take a breath and recognize that we're pretty much all out there to have fun. Yes, you'll have some folks who are very inefficient at the ramp, but getting all in a huff about it doesn't seem to make for a better time for anybody.
