Choose a situation.
Start with helm and momentum. Move into alongside approaches, slips, environmental conditions and independent exercises.
PILOT EDITION · IPHONE & IPAD
A calmer place
to get the
approach right.
Small inputs. Lingering momentum. A little room to try again. Explore boat docking one thoughtful attempt at a time.
A simulation to explore, not a qualification to operate.

Not a race to the dock.
A place to understand the motion.
THE PRACTICE LOOP
The useful part happens
between attempts.
Learn from the path you actually took.
Not just the result at the end.
Watch what happened.
Replay stored motion, scrub the timeline and find a control change. The simulation does not silently turn your attempt into a better one.
Try one thing differently.
Take over from a recorded moment with motion preserved. Your new fragment is separate; the original attempt remains intact.
A FLEET, NOT JUST A NEW PAINT JOB
Different hulls.
The same curious approach.
Single-outboard trainerSTART HERE
Training boat
One familiar hull. Room to understand what happens after you release the controls.

Pontoon configurationPRO
Pontoon 22
A different hull outline and estimated wind response, with the same deliberate controls.

Cabin 23
The longest configuration in this fleet, without a simulated bow thruster.

THE NOTEBOOK
Start with a better question.
PRACTICE NOTE · 4 MIN
Neutral is not a brake
Use the Inertia and Braking exercises to compare a control input with the motion that follows it in the simulator.
Read the notePRACTICE NOTE · 4 MIN
Review an alongside approach
Review approach angle, movement and the final neutral phase in BerthLab’s port-side and starboard-side exercises.

Read the replay, not just the score
Understand the timeline, telemetry-derived video, rule-based review notes and privacy choices before publishing a BerthLab attempt.

Your attempt.
A useful explanation.
Optional sharing turns recorded motion into a schematic video, a time-linked review and a place in the right boat and lesson channel after moderation.
