This is a bargain that every adventure traveller must have. Your air-ticket will come in handy. 2 Boards maximum . Ok I know you are going to ignore this advice. Airlines freak out when they see huge triple long board bags and may refuse to load them .
White bags are by far the best in the tropics.
Extra leg ropes. Board grip is better for most surfers than wax in the tropics. Booties for walking on coral reef. Helmet for sun and impact protection. Otherwise a stay-on surf hat with peak works well.
