Both my Fireflys were fitted with rotating masts, the fastest setup was to have the forestay slack enough that the mainsheet could be block to block upwind. For downwind, there was a jib tensioner to pull the rig forward and tighter the jib luff.
If one forgot to release this upwind, the boat was significantly slower. As Rupert states, the Reynold masts needed tight diamondstays - the section as too thin to be self supporting downwind (remember that the mast rotated). The later Proctor masts were more robust, nowadays, the mast is fixed with spreadrs, so it's a different setup. With regard to the Solo,one of the effects of slack rigging is that the mast can sag a bit to leeward, tending to open the leech upwind. With the fully battened sail, I suspect it is too easy to hook the leech. Colin |

what section ali mast was the Solo orginally built with ? given there are people sailing them now with D/ sleeved D / D+ and M7 masts - all fairly stiff and in the case of a D+ esigned to be extra stiff in the Ent with it's deck stepped Mast where as a lot of the olderboats look to have C or similar masts

Ive not seen a normal D on a Solo for years. I would imagine the gold masts are Ds and Cs not seen a B but i bet they were used too.
Anything semi recent wood be a Cumulus/C/Sleeved C/D+ or Superspar M1/Skeeved/M7

I remember Holt round masts with the track riveted on. Can't believe they were very stiff, but no real idea.
