IRC Time Calculator

Here’s the free IRC Time Calculator from UK Sailmakers to help you calculate the IRC times for your boat and competing boats. This calculator is an essential tool for handicap racing, making it easy to determine exactly how much time you owe to (or receive from) other boats in your fleet.

Using the calculator is simple:

1. Enter your boat’s name and TCC (Time Correcting Coefficient)
2. Add the names and TCCs of the boats you’re competing against
3. Generate your time tables to see the exact time allowances for various race durations

The calculator will create a comprehensive table showing time calculations from 10 minutes to 48 hours, helping you plan for anything from short afternoon races to long-distance events. The goal is to provide a straightforward and practical tool for estimating corrected times in a Time-on-Time (ToT) racing format. You can save the results and print them or share them among your fellow sailors.
