Honestly carpeting isnt that hard. You just need patience. I carpeted my old boat. If you can just tear the csrpet off and use it as templates. I used all contact cement for my boat. Most just use a waterproof glue then use contact cement for the edges. I would just try to replace a small section. Like a hatch door. If you feel comfortable just keep going. If not, you're not really out anything but maybe $20 in materials. I actually enjoyed doing mine.
