I am able to surf the Z1 with zero ballast and only 2 peeps in the boat. I'm 200lb's and ride a CWB Tsunami. We then filled the factory ballast on the surf side, filled the bow sac, and tossed a 400lb sac on top of the stock tank. The was awesome and the pocket was great. Still lots of push up to 12.5mph. Good riding boat, lots of storage, great options and upgrades available. Take it for a demo and see for your self if it's the right boat for you and your family.
