This is a real guidance output for one fixed sample slip. Change the wind below and watch the rating, diagram, and line order change. No account needed.

Sample slip

Harbor Point Marina (sample slip)

Great Lakes style slip, finger pier on the port side. 28 ft twin-engine boat, backing in.

Docking conditions

HARD

10 mph wind pushing your boat toward the finger pier. The wind will help push you toward the dock as you approach. Your boat may rub the fenders, which is fine. Let the fenders do their job. Keep all passengers' hands and feet inside the boat at all times. Only an experienced boater should assist with fending off, and only using a boat hook, never hands or feet against the dock or pilings.

Do this first

Secure your forward spring line first, it stops drift toward the headwalk.

Attach sequence
  1. 1.Wind pins the hull alongside, secure lines in any order once fenders are set

Keep fingers clear of cleats before lines go tight.

Harbor Point Marina (sample slip)

Easy

· 42/100

Good conditions for a relaxed, clean approach. Rig fenders and a midship spring line on deck, then focus on a low-speed final.

Confidence
80%
Biggest risk factor

Headwind on the bow (bow faces the fairway) pushing the stern deeper into the slip, control closure speed and be ready on the aft spring line.

Line handling · Transient dock

No lines are waiting for you at this dock, rig everything on board before your approach.

  • Hang fenders on the dock side at hull-rub height before you turn into the approach.
  • Pre-cleat bow, stern, and a midship spring line on the dock side, coil the bitter ends so they pay out cleanly and don't tangle.
  • Brief one passenger to step off (don't jump) with the midship spring first. That single line holds the boat while the others are set.
