Yes, you can bring your surfboard, boogie board, beach chair, etc on the bus. Larger items like surfboards, boogie boards and beach chairs will need to be placed in the luggage bays below the bus.
Although not necessary, we encourage you to bring your own padded surfboard bag. This will help keep it organized when in the luggage bays and help protect your, as well as other peoples', gear as items in the bays can shift while the bus is in motion.
