Open Water Navigation And Tidal Planning

  • Paddle
  • Sea Kayaking
  • Advanced


This module is for you if you're journeying open waters, including islands, over 2 nautical miles offshore in areas of strong tidal movement of 3+ knots and/or including winds of up to force 5. You'll build on the skills you've already gained on the Coastal Navigation and Tidal Planning course. It's a land based module delivers a number of practical planning exercises to give you the tools you need to plan and navigate safely in advanced water. Although it's theory-based, it's interactive, giving you plenty of opportunity to apply what you're learning.

The Objectives

You'll build on your existing navigation and tidal planning skills and knowledge, learning how to;

  • Interpret sources of relevant information including maps, charts, coastal pilots, tide tables and tidal stream atlases
  • Apply the information in calculating vectors, and negotiating open crossings and/or coastlines with no landing zones and/or tide races and overfalls
  • Develop the necessary knowledge to navigate on the water using advanced pilotage techniques in poor visibility or hours of darkness.

By the end of the course, you'll have planned at least two open crossings to take away as references for further trip planning. You'll also have gained an awareness of the range of resources you need to plan trips in any sea area.


* Please note: Itinerary is subject to weather and availability.

What to Expect

We'll cover the foundation skills during the first part of the day; computation of rates, tidal vectors, three different ways to address planning for open crossings. You'll then get chance to apply them by planning a range of real-world crossings using actual charts and forecast data.

Experience Required

You must have attended a Coastal Navigation and Tidal Planning course, or equivalent.

The sea can be an unforgiving and harsh place. Crossing large expanses of open water requires an effective planning structure. Ensure that you are in the right place at the right time to enjoy the challenge this environment offers.

Sid Sinfield

We'll provide all the necessary resources; practice maps and charts, compasses, line rules etc. And, naturally, an expert in their use to help you apply the principle to practical planning examples.
