Unfortunately not all 733's are the same hull. So not all tubes are interchangeable. Hurricane has built some one off boats where the only way to get a tube is to have one custom made either from the factory by sending the tubes back to them to duplicate or by using another tube builder who can pattern off of the original set.
Some boats it is just a change in the bolt rope positioning and others the tube is completely different. For example The "Sunrider" boat that Bryan took around the world was a totally custom boat built for that purpose by the factory.
