JET BLUE Baggage Fees "One board per case??

Hey guys,
I'm new to the site and was hoping you could help me out. I'm planning on flying JetBlue to Costa Rica in June and I saw that they charge $50 per board. Now I feel that this isn't that bad, however, their website also said you could only carry "one surfboard per case." I was hoping someone could tell me why that is and if there is any way around that? I have a two-board board bag and was hoping i wouldn't have to buy two additional single board bags for my trip, it just seems like a pain. If anyone has had any experience flying with JetBlue I would really like to hear your thoughts.
