MrPike, your boat will be fine. I stored boats outside for years, never an issue and in fact I think they are less attractive to mice when outside since they aren’t a warm cozy space like they are indoors.
Just make sure you have them well tarped so no moister gets in and NO POOLING of snow or water on top of the tarp. To accomplish this, you need a very steep A frame that will allow snow to slide all the way off the tarp and over the rail.
For lack of a better description, I built a custom “big sawhorse” for each of my boats. The top of the sawhorse had a 2×6 that ran the full length of the boat from bow to stern and the legs supported the sawhorse at the bow and right at the stern. The “top” of the sawhorse was about 4 feet above the floor of the boat, so you can see how much pitch is needed to get water to slide all the way over the rail. Each boat is different, so you have to do some custom design, but when done right this system works well, is sturdy, and easy to install and then store in the summer.
Build the sawhorse first, then buy a tarp to fit.
I will eventually store it for the winter, so once it’s really cold it’s going away. But that time in the fall where you might get below freezing overnight but still hit 50s during the day is my favorite fishing time.
Make sure you pour RV antifreeze in the livewell drain after each use so that water doesn’t freeze and burst the drain tube or fittings. Some boats have enough “pitch” to drain the livewell hose completely, but I would not want to take the chance with your Ranger as a burst hose could be a real beech to get at.
