One more question.... let's use 10 kgs wieght difference in this example. What order would you place the following (from most important to least important - obvioulsy all would help)?

1. New set of sails
2. Completely faired hulls, rudders, boards
3. Get boat/crew to minimum weights (10kgs)
4. Extra 5 hours practice each month

What else should be added to the list?


5. get the sail and rig trimmed
6. having a positive attitude
and I would split 2) in
2a. faired rudders, boards
2b. faired hulls *)

My ranking is:
6
4
5
nothing
1
nothing
nothing
2a
nothing
2b

*) long bodies are less sensitive to roughness than short bodies (i.e. rudders and boards) due to Reynolds number effects.

Cheers,
