(This will be my final post .... Paul)
At the International 29er Council meeting at Long Beach a decision was made to set up a new Technical Committee to look at Strategic changes to the boat (ie carbon mast) and the UK Class have proposed someone for that committee. This Committee is expected to report back in summer 2018 (I think ?) so while the carbon rig is being discussed it seems unlikely to happen in the very near term. More likely in a 1-3 year horizon and perhaps not at all - there remain plenty of technical and financial issues to deal with - nonetheless the idea is being investigated fully.
After this committee decides its preferences a vote is needed among all the National Class Associations so there is a long process required and it seems unlikely that this is an issue that will be resolved in the near term. Meanwhile smaller changes to the boat are being considered (ie like the new kick bars or foils). Here the process to have changes approved is much more rapid.
Changes to where the shrouds and trapeze wires attach to the mast (where corosion occurs) are being considered and we think would be retro fitted if passed. Also perhaps some changes to the Scuppers (the holes in the back that do leak sometimes). Finally a zip on the jib luff to replace the fragile plastic clips was agreed in principle (I think) though unsure when that actually happens.
This blog from the designer - Julian Bethwaite - is a useful place to see how he thinks the boat will change. Please note however these are only Julian's thoughts and the International Class (via the 29er.org website) has to approve changes then send them to World Sailing for Approval if they change the Class rules. So not all the changes proposed will necessarily happen but this does let you see Julians ideas for the boat. see below.
