Triple board bags are sensational for storing a lot of gear.. the only issue is with that much gear inside they are too heavy for the bag snatchers to carry onto the plane.
There are severe restrictions regarding how much weight you can travel with on a plane.
As we do a heap of flying with various bits and pieces we have had first hand experience with every conceivable weight issue as far as airlines are concerned.
The max weight for airline travel
used to be 32 kg
This has just been downgraded to 23kg
(you can still take up to 32kg but the penalty/fee for excess over 23kg has gone up astronomically.)
If the bags are predominantly for air travel in our opinion you are better off going 2 separate bags.
1 double board bag (board 1 sail and wetsuit/harness)
1 x all in one bag for the rest.
Axit you may be able to get away with all your sailing kit in an all in one (board, sails, mast & boom) and then pack everything else in a separate bag.
Depending on who you fly with and the ticket type you have will determine if you can take an extra piece of luggage or not.
Surfboards used to be considered sporting equipment which allowed you to take a board (which is not counted as your luggage) and then check in one more piece of luggage.
A windsurfer in a board bag can pass for a surfboard if you say the right thing to the check in person
*Formula boards do NOT fit into a surfboard description We have a flight coming up in the next week so will have full, first hand knowledge of new domestic restrictions and there implications on traveling with kit.
Will report back !
