hi all
i am just vondering what would be a good guide when lloking at a board volume wise, i know i would need something big as i am 6'2 and 120 kg bt i am looking for a rough guide

i currently have a paddleboard that is 11'6 that i paddle but i am unaware of its volume, i have been paddling for a couple of months so i am not a complete beginner but i am just looking for a rough guide as i am looking for a decent allround board
thanks all
