We don’t have a set weight limit because fitting in a kayak has more to do with your body shape than your weight. Similarly, being able to handle the full-day tour has more to do with your athletic ability and upper body strength than your weight. In fact, smaller guests with little arm strength might have more of a challenge than large guests with good upper body strength. If you have a pear-shaped body (upward triangle), we generally find that the upper weight limit for a guest to safely paddle a kayak is around 250 lbs. If you have a rectangular body shape or an apple body shape (downward triangle), we generally find that the upper weight limit for a guest to safely paddle a kayak is around 280 lbs. Our cockpits/portholes seats in the kayaks are about 18in in width (hip to hip). If you are concerned, please let us know and we will discretely help you make your go or no-go decision.
