Congrats on becoming a boat owner, Hometown, it'll open up a whole new aspect of fishing for you & your family.
Take a bit of time to get used to launching and retreiving your boat and you'll get the hang of it in no time as it's really very simple once you've tried it a few times.
If your going to be using that boat ramp in the river with the current alot, Gerritt offers some excellent advice about the trailer guides. They don't cost too much and just bolt on your trailer, but make life lots easier if your trying to load the boat in current or strong cross winds. Just basically drive the boat onto the bunks and the guides will do the rest for you.
