the hull is metal, hard metal which i found hard to waterline with a junior hacksaw, impossible with my first attempt using a minidrill an cutting blades,as you can see from Chis,s hull there are the supports which are a pain to cut through, holding the hull as you cut is hard ,a jig may help,if doing another i nthink a jig held in a vise would be the way to go! the rest is plastic and usually fairly easy to prise appart.i WOULD NOT TRY CUTTING WITH THE STRUCTURE IN PLACE! i found one quite enough to do!
