A surfski, kayak, or SUP can assist buoyancy aid if needed.
Always use the correct attachment for the equipment and conditions. Length and thickness of leg ropes vary according to board size.
Always wear a lifejacket with permanent, built-in flotation. Lifejacket requirements vary according to activity, check which is best suited to your activity.
Take two forms of communication (phone in a water-proof bag, Maritime VHF in waterproof case, voice (if close to shore), whistle).
But only if they are connected to you and the board.
