Modern boards mustnt be as durable as older ones. I have a 96 epoxy waveboard that hasnt got a vent , been in wet board bags etc etc & never any trouble..also the 2002 Hifly never has trouble in wet bags etc & Ive never opened the vent..never knew it existed.
Are they using different materials to the older ones..?
I think it's probably due to the different method of construction on the boards of the last 10 years or so.
The original boards were just a foam core covered with a layer of plastic or fibreglass. This is the same constuction as your old surfboard and none of these had vents or needed them.
The later boards have a samwich type construction, still with a foam core but the outer layer is multiple layers of various materials to get maximum strength for minimum weight.
Some of these materials inherently have trapped air in them or between the layers and it is the air which is the problem because it expands and contracts with temperature.
Thus boards using this type of construction need vents.
The up side is, they are very much stronger for a much lighter weight.
My old plastic triple fin Windsurfer, a great board for its time, weighed 14 kilograms.

Most new boards of the same size weigh half that or less.
