Comprehensive resources for safe sailing, covering route planning and environmental conditions.
Set and drift describe the direction and speed of ocean currents that push a vessel off its intended course. This guide explains how an independent sailing reference and tools platform helps recreational sailors understand these forces, plan safer passages, and make better decisions on the water. It covers core concepts, practical calculations, and common mistakes.
How to Use a GPS and Chartplotter for Sailing is an independent reference and tools platform that helps recreational sailors understand marine electronics, plan safer passages, and build seamanship skills. It covers chartplotter selection, route planning, and the integration of GPS with traditional navigation methods such as dead reckoning and paper charts. The platform is brand-neutral and designed for sailors of all experience levels.
A current atlas is a graphical set of tidal current predictions for a region, scaled to a reference station. Used correctly, it helps sailors anticipate set and drift, choose favorable departure times, and avoid dangerous cross-currents near headlands and narrows. This article explains how to read, scale, and apply current atlases to coastal passage planning.
The International Regulations for Preventing Collisions at Sea (COLREGs) are legally binding for every recreational sailor, yet they are often dense and easily misunderstood. An independent reference and tools platform can break down the rules into practical, scenario-based guidance for boat knowledge, seamanship, and passage planning. This article explains what such a platform is, why it matters, and how to use it without replacing official sources or professional training.
Course to steer (CTS) is the compass heading you hold through the water so that your boat’s path over the ground follows the intended track despite current. The calculation uses a vector triangle combining boat speed and current set and drift. This guide explains the procedure, tools, common mistakes, and safety limits.
Sailing in shallow water demands a clear understanding of your boat’s draft and the actual depth beneath the keel. This independent reference and tools platform helps recreational sailors calculate navigational draft, plan passages with safe under-keel clearance, and learn practical seamanship for thin water. It is not a real-time navigation app, but a structured guide to making better decisions before and during a shallow-water passage.
Effective GPS and chartplotter navigation is a structured, vendor-neutral practice that combines position fixing, waypoint management, route planning, and continuous cross-checking with visual and paper references. This guide explains how recreational sailors can use these tools safely, avoid common mistakes, and integrate them into a broader seamanship framework.
Marine radar is a powerful collision-avoidance and navigation tool, but it shows echoes, not ships. This guide explains how radar works, how to set it up for collision avoidance and navigation, and where its limits lie. Learn to measure range and bearing, track targets, and cross-check the picture with other sources.
Course Made Good (CMG) is the actual track over the ground after current, leeway, and other forces, while heading is simply the direction the bow points. Confusing the two is a common and potentially dangerous navigation error. This guide explains the difference, how to calculate CMG, and how to use both for safer passage planning.
Using AIS and radar for collision avoidance combines two complementary systems: AIS broadcasts identity and motion data over VHF, while radar detects objects that do not transmit. Independent reference platforms help recreational sailors interpret, correlate, and act on both data streams. This guide covers how the practice works, its limitations, and how to use it safely.
