Tidecomp Lite (an iteration of the classic TideComp software) is a lightweight, specialized marine tide and current prediction program designed primarily for mariners, fishermen, and long-distance ocean cruisers.
First developed in 1990 to run under MS-DOS, the TideComp family emerged as one of the earliest digital alternatives to bulky, printed paper tide books. Key Features of Tidecomp Software
Massive Database: Tracks and predicts tidal changes for over 4,000 coastal locations globally.
Visual Data: Generates clear 24-hour tide graphs alongside comprehensive monthly tide tables.
Cruising Utility: Built to work efficiently without heavy processing requirements, making it highly valued by long-distance cruisers.
Lite/Streamlined Format: The “Lite” or baseline versions focus strictly on harmonic tidal predictions without the extra data-bloat or high-end mapping overhead found in modern Marine Services Platforms. How Tidal Prediction Software Works
Programs like Tidecomp rely on mathematical algorithms driven by harmonic constants. These formulas calculate the complex gravitational pull of the moon and the sun on ocean waters relative to a location’s specific geographic layout.
The software measures these changes against a universal baseline known as the Chart Datum—the long-term average of local low tide heights—allowing boaters to calculate exactly how much actual water depth they will have at any hour of the day. Modern Alternatives
While TideComp pioneered early digital navigation, it has mostly been succeeded by modern, mobile-friendly apps and open-source equivalents that offer real-time updates and GPS integration, such as: TideComp 2000 Worldwide tide prediction program.
