Type of Boat?
What type of boat do you have? I removed mine on my O'Day 222 by accessing the carriage bolts on the inside of the stern. I removed the wood panel (starboard side, behind settee) and crawled around to get access to the bolts. The cockpit locker may be an option on another boat, but my lockers are too small for an adult. However, once I got the bolts loose, my 10 year old son crawled down into the locker and got the bolts unscrewed the rest of the way.
