Hi just wondering how long the general opinion is on how long a surfboard or a foil board should last for I'm saying no damage no cracks from user using regulary not jumping etc I was thinking maybe 3 years

Not long if it comes off your roof racks and under a truck.

My old North Wam lasted me 7 years, but in retrospect I should have replaced it after 3 or 4 years. Didnt realise how stuffed it was until I got a new one!

any surfboard or kitesurfboard that is not rubbish after costing less than 10 dollars per hour kited is great value.

I've owned a lot of boards over the years but I've had 2 last just over a year from delaminate the core separating from the outside skin shell With no damage visable and no damage done but both went at same age not impressed as boards are expensive to buy new and in my opinion should last longer than that
