This is probably really obvious but I thought i'd put it out there!!
Just got myself a 10'0 Naish Mana, with the timber veneer, after paddling a few cheaper made boards.
I didn't ask the guys @ dripping wet (too psyched to get it wet)but can someone shed some light as to what the phillips head screw behind the tail pad is for??
If you take the board on a plane you release the screw to ensure the air inside the board doesn't expand and destroy the board. You can also release the valve if you are leaving the board sitting in the hot sun or inside a car on a hot day. But you have to remember to tighten the screw again when you put the board in the water - you don't want water inside the board.
just took both of my naish boards on a plane without touching the screw and no problems at all. its just a piece of nice jewellery for your board.
