- Whenever one is trying to decide whether or not a particular aspect of
- racing, either equipment or technique, is faster, i believe the best approach is
- to think of it like this: if all else is equal and i only change this
- one variable on one boat, which boat will be faster? When condidering foil
- vs. hanks, you must assume that the crew work is perfect in both cases.
- Obviously, a poorly executed maneuver will cost you no matter what equipment
- is used. in strict one design racing, we will tune our boats exactly the same
- except for one aspect. then we go out and sail close to each other to see
- what effect the tuning difference has. usually, we will swap boats and repeat
- the trial to make sure the noted difference is really caused by the tuning
- change and not by the skills of the helmsman and crew.
