Sawing out the center section will be very messy and complicated and ultimately cost more than it's worth, unless your goal is to really learn how to work with fiberglass, lol.? I too suggest splitting the deck fore and aft while leaving the center section attached.? I found a rubber mallet and sharp paint scraper do this job easily and cleanly, which makes glassing the joint back together easy.? Kent is right that the deck at the bow can be bent upwards like a car hood (almost) to let you get into the front. The aft deck can also be pried up the same way, and this means your repairs won't leave a lot of portholes behind.
