There is no denying removable fins are convenient for travel, but that is all. As far as design and strength, go the removable plastic fins are just not up to the task, constantly breaking and too weak to with stand the extra pressure the wide thick tail produces. This is the reason all my multi fin designs have hand made fibreglass fins glassed on to the board for strength and performance as opposed to a fashion statement that is inadequate for the job. When travelling with glassed on fins, it is necessary to take precaution for protection.
Suggestion:
Get a piece of sponge foam rubber 1” thicker than the fins depth, cut it out slightly larger than the fin area and board. Hold it over the fins and mark these positions then dig out the holes for the fins to fit into. Push foam over fins, put board in travel bag and zip it up. By doing this, you will minimize breakage by rough luggage handlers.
