About

Dock Line Calculator

Features
Read full description

Dock Line Calculator is a mooring layout studio for boat owners. Draw your boat at its berth, set where each dock line attaches, measure each line on the real boat and keep the whole plan in one place. HOW IT WORKS 1. Vessel: enter length overall, beam, bow freeboard and cleat positions once. 2. Berth Layout: choose alongside dock, finger pier, slip, stern-to or your own arrangement, and the dock side. 3. Line Plan: tap a line on the drawing or in the list, choose where it attaches, enter your own measurements and mark it verified once you have checked it on the boat. 4. Rope Inventory: enter the rope you already own, add a waste allowance and see what is left to buy. 5. Export: share the plan as text, PDF or CSV. WHAT YOU GET - A top-down drawing of your boat at the dock. No dragging needed: attachment points are chosen from lists and the drawing follows. - Bow, stern and spring lines with rule-of-thumb starting lengths and diameters (the same figures as earlier versions). - Every length shows where it came from: rule of thumb, geometry estimate, measured by you or adjusted by you. The app never replaces a length you entered. - A chafe and movement checklist for the real berth: chafe protection, cleats, fenders, tidal range, line lead, expected movement and marina or manufacturer requirements. - Several vessels and plans, with side-by-side plan comparison. - Anchor snubber and bridle leg figures from your bow freeboard and beam. - Feet or metres. Light and dark appearance. iPhone and iPad. - Offline. No account. Your data stays on your device. IMPORTANT Dock Line Calculator gives rule-of-thumb starting points and records your own measurements. It is not an engineering standard, it does not state breaking strength, it does not say a line is strong enough and it does not certify a mooring as safe. Your rope maker, your marina, your insurer and a competent marine professional come first. FREE AND PRO Free: the basic dock-line figures, the mooring studio with the standard lines of one plan, your own measurements, the chafe and movement checklist, one saved vessel and text sharing. Pro (one-time purchase, no subscription): more vessels and plans, plan comparison, snubber and bridle figures, rope inventory and shopping list, additional custom lines, PDF and CSV export.

Verdict

The call

The clearest difference is in-app purchases: World Clock at none against Dock Line Calculator's 1. World Clock also leads on update cadence (every 10 days vs every 2 months). Dock Line Calculator's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
