@Bartableman7, are you able to get enough of the bunks wet to allow the boat to be pulled off the trailer with a rope, or as @RatherBFishin stated, you could push it off?
I never thought of power loading as a way for people to look cool, though there is always that guy, right. I believe power loading is the most efficient method of removing a boat from the water by oneself. To power load without creating holes at the bottom of ramps, I do the following:
Get the bunks completely wet and position the trailer at a depth so that the boat slides right up to the roller with minimal throttle speed.
Cut the throttle as the boat reaches a certain point on the bunks, allowing momentum to carry it the rest of the way up.
Do not gun the motor to get the boat up to the roller.
If you fall slightly short of the roller, winch the boat up. (If unable to winch it up, get back in your vehicle and back it down a few inches to allow the boat to be winched up. Believe me, doing this does not look "cool" but it is still quicker than other methods.)
Once you do this a few times with your boat, you learn the right depth for your trailer to get the boat up to the roller without having to get back in your vehicle to adjust.
