Sailors have figured out that the perfect way to spend time at the dock or at anchor is to go paddleboarding. With its rubber construction, the Walker Bay Airis HardTop standup paddleboard is perfect for sailors. It stows away in a large backpack and inflates so firmly that you’ll be hard-pressed to tell the difference between it and a typical SUP. The 11-foot version is $899.
