Bigger is Better.....
Okay, not exactly correct, but the 34 Mark I offers a little more head room (1") and 2" longer berths in the V than the 32. After that, the boats appear to be very much identical. Same cockpit size, same beam, and water line. Yes, the 34 is sligthtly longer, but the wetted surface will be about the same on both boats as is the ballast and drafts as you already know. I am perplexed on why Sabre chose to make and overlap the 32 and the 34 Mark I and the 32 and 34 Mark II in model years. The 32 comes at the tail end of the 34 Mark I years and the beginning of the 34 Mark II years. 34 Mark I stopped in 85 and the Mark II was started in 86.
I have never been in a 32, but the 34 is tight from the head forward. Also the cabin sole in the head/v-berth entrance is slightly curved up (ie not flat) in the 34 Mark I.
Based on the measurements, my guess would be what you are already thinking, everything else being the same except for a little more sail area, the 34 should faster than the 32.
