Maxi Cats are still relatively new and designers are lacking the knowledge of the stress these boats will be under as they found out on 'The Race' boats. With more data gathered from racing in real life conditions as apposed to on a computer the more reliable the designers predicted stress calculations will be and the more reliable these boats can be build, reducing the downtime repairing breakages. The boats will also become faster because of this and the skippers will have the ability to push the boats closer to its ability as at the moment the limiting factor on speed is the boats ability to handle the punishment.

With the data gathered from 'The Race' boats and maxi cats in the near future...... You should not have a problem designing a reliable multi for around the world or Sydney to Hobart.

Remember also that maxi multis are very under-developed and under-researched compared to canting keels which were originaly first seen some 30 years ago or Maxi Monos. I think the biggest challenge would be trying to convince the CYC that a Multi is just as reliable / safe or even more so than a mono
