Boat Question. Indian River

This may sound like a dumb question to all you Floridians, but being from Kentucky I am a little confused. I fish bass tournaments up here in a typical 18ft pro craft bass boat, I was told it would be a bad idea to bring it to Florida to fish on the Indian river. I kinda understand why shallow sides, electronics aren't suited for saltwater corrosion and such, however I also mentioned purchasing something like a aluminum style Lowe stinger 175 and the boat shop I was talking to kinda shot that idea down.

I would like a boat I can use at both locations here and on the Indian river. I visit Melbourne Fl 6 or more times a year and love fishing near the Sabastian inlet. I know a center console is ideal for that area, but not so much up here. Can anyone recommend a good boat for both locations or tell me why something like a aluminum style boat like a Lowe wouldn't work?

Appreciate the advice.
