Welcome to the site...hope you can post some pics of your 18 soon...I bet she gets it pretty good w/that 150!!...
The wear and damage, plus Dad tossing the rod boxes sounds like you could put a lot of time and money into it which is fine...but use caution if your idea is as you say;fix it up so you can sell it...few get back what they have put into a boat, especially these days...if you are the fiberglass, electrical and all 'round Mr Fix-It, you stand a better chance of recouping your costs on resale...
Pics when you can...
