FAQ on SUP boards, paddles and accessories.
Do I need to vent my board?
Thanks to the Gore-Tex® vent plug, your SUP board vents itself. The vent plug ensures that expanding air is let out while being water proof. Do not remove or loosen the Gore-Tex® vent plug as the membrane in the vent plug may get damaged.
Only remove the Gore-Tex® vent plug if water has entered the SUP board, e.g. through a crack ding in the lamination shell. If that is the case, carefully loosen and remove the vent plug and store the SUP board in a dry place to allow the water inside the board to evaporate.
Do the wooden boards require any maintenance?
Our wooden boards are made of FSC© certified wood, which ensures that the material is produced through responsible forestry.
The wood material consists of a layer of wood veneer between two layers of fiberglass fabric. In other words, there is a layer of invisible fiberglass fabric on top of the wood material. This makes the SUP board sturdy and shock resistant, while allowing for the natural wood to be fully visible. On top of the outer layer of fiberglass is a layer of polyurethane varnish that makes the SUP boards glossy and completely waterproof.
So, in other words, no maintenance is required.
How do I position the fin in the finbox?
Depending on where you position the fin in the finbox you will get different charatcheristics of the SUP board. If the fins are placed towards the front of the finbox, the SUP board becomes more manoeuvrable, but at the same time less directional stable. If it is placed far back, you get maximum directional stability, which means you do not have to change the paddling side as often. The board is also less sensitive to side winds. For normal paddling in lakes, along coasts and archipelagos we recommend placing the fin as far back as possible.
There are air bubbles underneath the pad
On the bottom of the pad there is a layer of strong self-adhesive 3M glue. This makes the pad adhere to the board and prevent it from sliding. During manufacturing, bubbles may occur between the pad and the board. In the event that they occur, they are detected during quality control and then punctured so that the adhesive can re-adhere to the surface of the board. However, depending on the temperature fluctuations, bubbles may grow afterwards. In that case, take a thin needle and punch hole in the middle of the bubble and massage the bubble from the outside to the centre of the bubble so that the trapped air can get out. The pad’s self-adhesive surface will then reattach to the surface of the board.
Does my paddle float?
Yes, all our paddles do float. Although carbon fibre and fiberglass itself sink, the air pocket inside the hollow shaft will keep the paddle floating.
Can I tow my board behind a boat?
The SUP boards can be towed behind a boat in the nose leash plug or D-ring short distances at low speeds. Use an elastic towing cord to relieve the leash plug or D-ring.
Can I keep my hard board outdoors?
You can keep your hard board outdoors all year round, but read this first:
When not using your Yster SUP board, keep it in a dark and cool place where sun and heat do not reach your board. A good alternative is to store it in a board bag, which protects the board from heat, sunlight and shocks.
Keep away from heat
Dark SUP-boards get very hot if they are exposed to direct sunlight, also, in a short while. All Yster SUP boards are equipped with Gore-Tex® vent plug that allows them to breath. However, if they get hot the core material which largely consists of air, will expand. This may cause the lamination of fiberglass- or carbon fibre to detach from the core causing air bubbles between the core and the lamination.
Keep away from sunlight
When the SUP board is exposed to direct sunlight for a long time, the colours will fade. Although this does not affect the performance of the SUP-boards, the colours will lose their lustre and brilliance.
I believe that my ISUP is leaking.
If you suspect that the board leaks, inflate it and lather it in a mild soap. Small bubbles will then appear at the leak. However, commonly the pressure drop is caused by exposure to cold water or drop in ambient temperature rather that a leak.
