I daresay that this is not an easy problem to solve, and furthermore the only boat one knows well is his own.
Boats differ considerably from each other.
Everything is discussed and agreed together but the final decision is made by the helmsman. Everything begins with putting the iceboat together. If this is done smoothly and quickly, we may expect that the other stages of iceboating will also go well. In a team where men have been racing together for a long time, both have leamed to share tasks and obligations, so neither one is disturbing the other. A Monotype XV can be assembled by her team in 20 minutes, from unloading the boat from the car or trailer until hoisting the sail.
