The "apparent wind" doesn't change for each sail. ( Apparent Wind Calculator )(I just read that webpage, ignore when they say anything about the wind being "forward", it is wrong!)

When there are multiple wings(spinnaker, jib, main) working close to each other, they work together and each one effects the airflow over the other wings(spinnaker, jib, main).

This is what causes the main to need to be trimmed in closer to the centreline than the spinnaker, not the apparent wind.

Just thought we should clear that up first.

Otherwise, you've got the idea, except that you should drive deeper as you accelerate and round up when you decelerate (That's because of the apparent wind.), constantly trimming the sails (spinnaker mostly) to keep them operating efficiently and providing maximum drive.
