Rudders replaced as the original McKenzie ones had heaps of problems. Can't remember exact details, but the locking mechanism was stuffed and I think they were cracking.
If they are still using the original Blade mast, then there is a big hole at the bottom of the mast where the original spanner was. Either bad installation or bad design, but the bolts really ripped up a big hole on either side of the mast so this is the only alternative. Much prefer the desk sweeper, a lot less friction and prefer rotation to be independent from mainsheet tension.
Wouldn't mind seeing a high aspect board on this boat rather than the fat Taipan boards.
