SUP boards which are solid (made from various composites and do not require inflation) have to be rated as the best paddling craft currently on the market and are surprisingly a more stable platform than the inflatable boards. This is due to the solid boards displacing the water and sitting 'in it' rather than 'on it', as most inflatables do. Their Achilles heal is that the boards do need to be treated with far more care than an inflatable as the hulls are reasonably fragile and when it comes to transportation and storage, that can be where the problems start. The trouble is, once you have paddled a solid board you are likely to want one, especially for playing in the waves!
