I’m not much for suggestions on Pool 3, but if you ever need some on Pool 4 I have been in most of them either refueling or picking people up and can give suggestions.
I’d go check them out and get your name on waiting lists for ones you prefer. I know one here locally has a ~2-3 year waiting list while the other generally has a handful come available each year in the less desirable sections of the marina.
We recently went through this process with our tritoon so that my wife could use it whenever she wants when I am not around. She is very comfortable growing up on the river, but doesn’t want to launch it alone from a trailer. If you choose a place, I’d ask specifics about:
-carry in fuel policies (most don’t allow it, but if they do it’s a plus)
-lockable storage on docks
