Pretty boat, the A33...

Lots of good points made above.. we're sailing a 3/4 frac with a small headsail (100% or so) and find that we're lacking below 8 knots true but pretty comfortable and moving well above that, though we're not racing so don't have a direct comparison.

In many cases, esp with the large J dimension boats, using a 120% jib results in poorer sheeting angles than a 150 because the shroud base can't fit within the camber of the sail, resulting in reduced pointing ability. On a previous IOR masthead 40 footer we left the #2 at home and used the 155 or the working jib depending on conditions. (Upwind sailing was the only way to get anywhere from where we lived)

In the case of the Abbott 33, though, she's probably narrow enough to get by. So then it's a numbers game as you compare the rating break vs light air losses..

As to what material to buy, we've had good results with 'hard' dacron mains and pentex headsails on our last couple of boats.
