Rainbow's End Anchoring

May you find a rainbow’s end and treasure found wherever you sail or set your anchor — this calculator helps you choose the right anchor and rode setup for any condition. Rainbow’s End Anchoring works out how much rode to pay out from what actually matters — the depth under you, the height of your bow roller, the tide, the wind, and the holding ground — then picks the best anchor and rode combination from the gear you actually carry, and says plainly when something will not work. • Scope measured from the bow roller down, not the depth sounder alone • Recommends from your own anchors and rodes — and warns when the locker cannot support the plan • Regular anchoring, Bahamian moor, Med mooring, and lines ashore • Storm mode with a two-anchor plan • Gusts raise the scope and the peak loads • Honest chain catenary: know the wind at which your chain pulls straight • Swing circle, under-keel clearance at low water, and the deepest water your rode can take tonight • Multiple boats — your own, a charter, the dinghy • Feet, meters, fathoms, shots, or your own rode marks • Works entirely offline. No account. Your boat’s details never leave your phone. Built with real seamanship and honest about its limits: every figure is an estimate, and your judgment always outranks the app.
