I'm not certain about your specific model of boat, but on most fiberglass hulls, there is a rubber bump or rub rail above the waterline. If you pull off the rubber center piece, you will find either rivets or screws that will allow you to pry the hull apart once removed. Please note that I have seen info stating that some hulls may warp after removing the top, so this should probably only be done as a last resort.
It would depend on the construction of the craft, but as a general rule, the fiberglass boat will be heavier.
It all depends on the purpose of the craft and the weather. On a good day, you'll see any size of boat, but on a bad day, I'd recommend at least a 18ft boat (not an aluminum Jon boat, fiberglass is usually a safe bet)

Fiberglass is actually very flammable.
I would think a fiberglass boat is better than a wooden boat because a wooden one can rot and would be hevy to move weres the fiberglass boat wont rot and is light so would be easy to move.
A sponge and some fiberglass sealers works the best on a fiberglass boat. There are other fiberglass cleaning material available depending on what your particular need is. For just basic cleaning, I would go with the sponge and fiberglass sealer.
You can remove dried barnacles from a fiberglass boat using a stainless steel scrubber or a pressure washer for large barnacles.
If you inflate any rubber craft too quickly and too much ,the rubber will separate.
A boat floats by keeping water outside, regardless of any material

Vietnam War PBR's were built of fiberglass; they worked fine. That's the boat in the film Apocalypse Now.
