400 lbs bags should be close. I have one in the locker behind the driver’s seat and it’s a perfect fit in my 2020 Mojo, you might not be able to completely fill it in a Craz. I think the 400# bag will be a close fit in the bow. I am still dialing in the goofy wave but my son, who is a freakishly big 6’5” 320lbs, surfs ropeless all day long. The extra weight on the starboard side will surely clean up your wave from what you have right now.
