What to practice
Start with the trainer before changing boats. Repeat the same calm-water exercise and compare the moment you select neutral with the moment the boat actually slows.
What the model includes
This is BerthLab’s original, fictional training hull. Its 7.20 m length and 2.60 m beam are model dimensions. The controls, recorded trajectory and replay timeline provide a common baseline for the rest of the fleet.
A focused comparison
Run Inertia, then Braking. Change your input timing rather than the weather. At the end, compare the last powered frame with the first neutral frame; selecting neutral does not erase the recorded velocity.
