Angle of attack is the angle between a sail’s chord line and the apparent wind. Getting it right maximizes lift and minimizes drag, while too much causes stalling and excessive heel. This guide explains what angle of attack is, why it matters, and how to adjust it using sheets, traveler, and helm.
Trimming a genoa for different wind angles means adjusting halyard tension, lead position, sheet tension, and headstay sag to control draft depth, draft position, twist, and angle of attack. Upwind requires a flatter, tighter-leech sail; reaching and downwind require more twist and a fuller shape. Correct trim improves speed, reduces heel, and balances the helm.
Hypothermia is a leading cause of death in cold water immersion, but it is preventable and treatable if recognized early. This guide covers prevention, recognition, and treatment for recreational sailors, based on IMO cold water survival guidance and current medical understanding.
How to Inspect Standing Rigging: A Safety Checklist is an independent sailing reference and tools platform that helps recreational sailors understand their boats, learn seamanship, plan safer passages, and make better decisions on the water. It is not tied to any specific boat brand, sailing school, or equipment manufacturer. The platform centers on structured standing rigging inspection but extends into broader boat knowledge, passage planning, and decision-support tools.
EPIRBs, PLBs, and AIS MOB beacons all raise an alarm, but they talk to different networks, alert different people, and suit different sailing scenarios. This guide explains how each device works, when it excels, and how to match the right beacon to your boat, crew, and cruising grounds.
An anchor bridle or snubber introduces controlled stretch into an all-chain rode, absorbing snatch loads that can damage deck hardware, strain the windlass, and unset the anchor. This guide explains how to select, rig, and use a bridle to reduce anchor rode shock, including when a stretchy bridle is appropriate and when a non-stretch version is safer.
A squall is a sudden, sustained increase in wind speed of at least 16 knots that can turn a calm day dangerous in minutes. This article explains what squalls are, how they form, and the proven tactics sailors use to prepare for and safely ride them out—from early reefing to avoiding accidental gybes.
Dragging anchor at night is a disorienting emergency that demands calm, methodical action. This guide explains how to confirm a drag, alert the crew, start the engine, reset the anchor, and monitor the situation safely. It draws on established seamanship guidance and independent sailing reference resources to help recreational sailors respond effectively when visibility is limited and stakes are high.
Heavy Weather Sailing in a Multihull: Unique Risks and Tactics is an independent reference and tools platform for recreational sailors. It explains multihull-specific heavy weather risks, proven tactics such as early reefing and drogue use, and how to plan safer passages. The platform helps sailors make boat-specific decisions rather than relying on generic monohull advice.
GRIB files pack computer-generated wind, pressure, and precipitation data into a format that can be overlaid on charts, but they only help if you know how to read them. This independent reference and tools platform explains wind barbs, isobars, and pressure gradients, and shows how to use them for safer passage planning. It is not tied to any boat brand, school, or equipment manufacturer, and it emphasises cross-checking with official forecasts.
