That all SOUNDS good Luis, but most if not all of what you say is negated if/when the bows are "lifted" during the tack by the crew "roll tacking" and taking their weight towards the stern of the cat through, and coming out of the tack. The fact remains that if the C/B's are well forward of the C of E of the combined sail plan, there will be weather helm which is not a very desirable situation, particularly if/when the helm makes your arms want to drop off on every beat. When boards are “too far forward” a tack can/will often be lost when coming out of it due to the boat wanting to immediately round back “up” after it has passed through the eye of the wind, all because of the “excessive” weather helm generated due to the C/B position, which can/will often cause the cat to “go into irons”. This same effect can also be generated by a crew keeping their weight too far forward coming out of the tack and creating a similar effect of having the C of LR too far forward and the associated weather helm rounds the cat back up into irons. One of the main reasons for “easing” the mainsheet during the tack is to obviate this “round up/weather helm” effect.
