I sailed my wave this summer with me (285 lbs), my wife (160){hope she doesn't read this }, my son (295), and grandson (70). The going was slow, very light winds. but had plenty of room and lots of fun, til the breeze died. I've put over 800 lbs in a nice breeze and did fine.
I have the club model and car topped it without any problems, takes about 20 minute set up once you get the hang of it.
