No, I guess not but then the HR 29 is a fin keel boat not a full keel boat.
In what regards the HR 29 the hull is just more adapted to sail upwind with waves and that has to do not only with a lot more rocker, a more narrow hull but mainly with a much bigger D/B ratio. The HR29 is a well designed boat, a stiff one. I don't like the SO 30 that is a boat with an unusual low B/D. That makes it tender upwind with waves and that's the main reason for its bad performance.
If you had against those boats, on those conditions, a modern stiff boat, the boat would be less comfortable but would be faster.
Have a good Christmas
