There will be a difference if you primarily trailer your boat or moor it for the season in one location. It also matters whether you boat in fresh or salt water.
If you trailer your boat most of the time, I would agree with the majority of the the maintenance recommendations the others have shared. If you plan on mooring it on freshwater, I will share my experience.
I have had my current boat since 2011. I often moor my boat on a freshwater lake for the season. When I asked the boat dealer what the best wax was to use on the hull to protect it from the staining (usually its algae growth), he told me to never wax the hull. Everything above the water line is fine to wax, just not the hull. I was shocked to hear him state that! He told me that when wax is used on the hull, it somehow helps to create a path for the algae to find it's way under the gelcoat and when you try to clean the hull, there often is a residue of stain that doesn't ever seem to want to come out. The first year I had my brand new boat I was a little nervous, I was hoping he was right because I decided to not wax it! At the end of the season, the proof was revealed. Spraying the hull down with a solution of Oxalic or Muriatic acid removed all the staining and the hull looked like new again. 9 years later, the hull still looks like new, I was really glad he shared that experience with me. Although I do have the dealer perform this and have never been disappointed in the results, I'm sure it would be fairly easy to do yourself as well if you have a fitting place to do it.
