SlipPlan turns tomorrow's actual forecast into a docking plan for your boat in your slip — with a role card for every crew member. The last 100 meters, finally handled.
Two hundred yards out, the wind has come up — of course it has — and it's blowing straight across the fairway. Your crew is holding a line, waiting for instructions you haven't figured out yet. The dock has an audience.
That knot in your stomach isn't a confidence problem. It's an accurate read: marina fender-benders are the biggest single class of insurance claims, the physics of wind, current, and prop walk genuinely is confusing, and every tool you own quits at the marina entrance. Your $50 chart app calls it "dock-to-dock routing" — and has no idea your slip exists.
A delivery captain entering a strange marina in 20 knots has already answered seven questions: wind, current, escape route, commit point, first line on, fender side, who does what — and the one word that means abort. Certification bodies agree: ASA's docking endorsement literally requires a written docking plan before you touch the throttle.
SlipPlan builds that plan — from live data, for your boat, in about a minute.
Keel or drive type, prop rotation, windage. Which way your stern walks, how fast your bow blows off — computed, not guessed.
Trace your real fairway, fingers, and pilings. Not "Harbor Scenario 7" — your geometry, your neighbors.
Wind, tide, and current at your arrival time, drawn as arrows over your slip. See the crosswind before you feel it.
Approach angle, turn point, first spring line, animated step by step. Plus what goes wrong, and exactly where your bail-out point is.
Position, line, cleat, fender, hand signals — shared to their phones before you cast off. The shouting stops.
Drag the wind to 20 knots on your real slip some rainy Tuesday and watch the consequences. Confidence, on your geometry, unlimited.
Everything works offline. Nothing you pay for ever gets re-locked. 14-day free trial on every plan.
Practice without a plan rehearses your guesses. SlipPlan is the plan — and its What-If mode is practice, on your real slip instead of an empty bay.
Until the afternoon it isn't. The go / no-go window flags the day the 4 o'clock gusts arrive before you're committed — and tells you when the calm window opens.
Joystick authority runs out near 20 knots of beam wind — and the plan is mostly about wind, current, lines, and crew. Physics no joystick removes.
Under $3 a month, a buy-once lifetime option, offline-first, and nothing ever gets re-locked behind a new tier. We priced it against the $150/hr lesson and the $500 gelcoat repair.
