Frequently Asked Questions

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.

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.

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.

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.

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.

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.

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.
