Good warranty is important. This is a great question, and another good reason to invest in a known, respected brand of Paddleboard. Obviously each brand has different warranty lengths, but currently at the top of their game is Jobe watersports. They have just introduced a 5 year warranty on their range of Paddleboards - this replaces the 3 year warranty that they had been offering for the last few years. In our opinion, this warranty length speaks volumes as to their confidence in the quality of their products. O'shea, offer 12 months, which can be extended by a further 2 years once you register the board on their website.
