v20 101 - aka help me I'm a newb!

[irimi]

Hey guys, My wife and I just got our first "real" boat, an 84 v20 Fisherman with an old yamaha 200 outboard. We've had a jetski for about 10 years, so we are somewhat familiar with trailering and launching, etc. Can you guys give me some good reading on v20 101? Like things to look out for with this boat, common issues, cool fixes or add-ons, anything like that? Our boat is overall in very good shape...doesn't appear to have any soft spots or dings anywhere and the transom is good and solid. We are in Charlotte, NC near Lake Wylie, so our primary boating are will be the lake, with the occasional trip to OBX. Any boaters in the same area want to show us the ropes? :) Also is it worth it to get a slip? We have an opportunity to rent a slip for a good price, but I've heard that keeping a boat in the water can make for additional maintenance? Thanks!
