Question: can you duck dive a 7ft board?
Answer: Anything under 3 ft barely requires duck diving at all, especially if you're on a board larger than 7 ft. I'm 5'8", 160lb and regularly duck dive a 7'4 and 6'9 funboard. It is hard and on days I anticipate a lot of duckdiving I switch to my 6'6 thruster. A few tips that helped me out.
