I walked through the 2018 SA at my local dealer this Saturday.

Biggest design change is the tower is totally different and it is a power tower now that lowers and raises from a button up underneath the tower.

The windshield is a different design, especially the sides and how it cuts back into the gunnels. I also want to say it is a flat black instead of the polished metal that the 2017s are.

It also comes with a Supra FAE on it that I am hoping is an option that I can order and add to my 2017.

It still has the ballast bags in front and rear lockers, so no all sub-floor ballast.

It does have the new auto-surf with amplitude.

Tower, FAE and windshield are pretty cool looking, but nothing that made me have total boat envy over the 2017. My sales guy did mention that the list price on the 2018 SA has gone up substantially!
