THE THING TO NOTICE
Use a stern-first attempt to observe alignment before entry and hull movement during entry. Compare it with the bow-in exercise rather than assuming the same inputs produce the same path in reverse.
Understand the exercise before starting
Select the slip chapter and read the lesson objective. Bow-in and stern-first scenarios differ in the intended entry orientation. The scene is an authored practice environment, not a chart of a real marina. Confirm which end of the model is intended to enter before you begin moving.
Observe what happens outside the slip
Review a frame before the hull reaches the slip opening. Compare its orientation with its path over the next few seconds. If substantial correction is still required at the opening, try a new setup in the simulator rather than judging the attempt only by whether it eventually fits.
Compare the hull configurations carefully
A larger hull or a pontoon outline changes the space the model occupies. Keep the lesson and environment constant when changing vessels. Current fleet configurations use estimated low-speed coefficients, not measured reproductions of named manufacturer boats.
Use abort practice as part of the lesson
The Abort a slip exercise is a separate goal, not a failed completion disguised as a success. Takeover also creates a fragment, not an authored lesson completion. These distinctions matter when reviewing shared videos: a short clip, a fragment and a completed course attempt are not interchangeable.
