The IHO’s S-100 series introduces advanced digital products—S-101, S-102, and S-104—that enhance maritime safety, efficiency, and future readiness through upgraded charts, detailed seabed mapping, and integrated tidal data.
Thursday - 28 August 2025
The International Hydrographic Organisation’s (IHO) S-100 series of products are coming to transform your voyages, making them safer, smoother, and more efficient. Phase 1 of S-100 introduces three new products, known as S-101, S-102, and S-104.
Let us explore how these three S-100 series products can elevate your navigation and fleet management with confidence and ease.
S-101: Upgraded Charts for Confident Navigation
S-101 is the modern successor to S-57 ENCs, delivering significant improvements tailored to your needs. Here is why it is a step forward:
S-102: Detailed Seabed Views for Safer Voyages
S-102 offers high-resolution bathymetric data, providing a detailed map of the seabed far beyond S-57’s basic depth points.
S-102 delivers peace of mind in complex waters, while fleet managers benefit from happier crews and lower operational costs.
S-104: Simplifies Tide Management
S-104 integrates real-time and forecasted tide and water level data directly into your ECDIS, removing the hassle of manual tide tables.
S-104 makes tidal navigation effortless, and fleet managers will value the streamlined port schedules.
Additional S-100 Products
The wider Phase 1 products also include valuable tools like S-111 (Surface Currents), which displays ocean currents on your ECDIS. Imagine planning a route that leverages currents to save fuel or avoids strong flows to stay on course. Combined with S-101, S-102, and S-104, these tools provide a comprehensive view of the marine environment.
For fleet managers, this translates to more efficient routes, reduced fuel costs, and a more sustainable operation.
Why Adopt S-100?
Transitioning to S-100 is about enhancing your daily operations and preparing your fleet for the future, with the key advantages being:
Navigating the Transition
Change can feel daunting, but the industry has you covered. Your ECDIS will likely require a major update, and your crew will need training, but chart providers are offering S-100 trial data, and pilot programmes allow you to test these tools easily.
