Boat shopping as we are looking to move up from our current 24’ Superboat CC. I’m going to have a look at the new SB Black Label 29 this Friday, and I’ve also talked to Concept regarding their 27 and 30 Open CC’s.
Not interested in a boat set up for fishing. Want to be able to comfortably take a total of 6 adults. Needs to ride well in the rough stuff. Arch rather than a T-top. 60-70 mph top end, ability to cruise anywhere from low 30’s to mid 40’s.
Other than SB and Concept what should I be looking at?
Not many performance boats around here as it’s all about fishing.

Renegade has the same styling as concept, I'm in the hunt myself, I've got myself talked into a 30' concept, now I just need to find the one

I like the 30 Power Play Rum Runner in that size range. A bit slower, but will hit the speed your looking for with the right power and be a much more confortable ride and space than what you are looking at.

Nortech 340 a little bigger than your choice, but hard to beat.
Intrepid has some good choices in your size range too.

My buddy has a 298 Nor-Tech CC and it is a beast for it’s size!
He loves it!

Not a lot to choose from in that size range. I owned a 30 Concept. It will do what you are wanting. It depends on what you call rough stuff as far as the ride.

I owned a 30’ Concept as well.

It ran nice, very much like a sports car. Good in the rough for its size, but it is a light boat. I would recommend it and the brand in general.

Well built.

have ran a 28 glasstream proxs a few times. it was nice

This might be a little different, but have you looked at the Axopar 28? Many configurations to pick from:
