Specially designed fishing SUPs have built-in systems that add stability to your time on the water. If you find that this is still not enough there are inflatable pontoons you can attach to your board which ensure you can walk around without tipping at all. These add-ons make it slightly more difficult to paddle but give you the ability to go out even in rough waters with ease.
We strongly recommend boards that are at least 6 inches thick to fish on. This gives you the capacity you need for all your gear. It also ensures that you can sit above the water without getting your feet wet. This may not sound like a big deal but it will allow you to take out your board even in the winter.
