If you are going air freight, the best (safest for your gear) would be to make a pallet the size of your boat, pad and wrap the boat. Fasten it to the pallet with metal bands and then wrap the hole thing again, then put don't crush don't double stack warning signs on the top (they are little cardboard pyramids).
The folks that handle air freight are rough as hell with the freight, I know I used to do it for a living. If you don't have stuff palletized so it can be easily handled with a forklift, it will be abused, those guys don't like having to get off the fork. If you don't put no double stacking warnings, it will probably end up under 3000 pounds of other shit.
This can be all done yourself but dropping and picking at the airport, and clearing customs, can be a real bitch. There are lots of companies that just do air freight, they could do everything, you just drop your gear at their warehouse and pick it up at another, but it'll cost a few hundred dollars more.
