How to Navigate the Lock at Chichester Marina – A Yacht Owner’s Guide

Chichester Marina is a fantastic base for sailors looking to explore Chichester Harbour and beyond, but if you’re new to the area (or just haven’t tackled the lock before), the thought of getting through it can be a little daunting.

Don’t worry - once you know the process, it’s straightforward, and the marina staff are always on hand to assist. Whether you're heading out for a day sail or returning after a long voyage, here’s everything you need to know about safely navigating the Chichester Marina lock.

Understanding the Chichester Marina Lock System

The lock is there to maintain a constant water level inside the marina, preventing boats from running aground at low tide.

It operates on a traffic light system, which we’ll break down shortly.

At high water springs, the lock gates can be left open, allowing free-flow movement in and out of the marina. However, for most of the tidal cycle, yachts will need to go through the locking process.

The lock operates 24/7 (except in extreme weather), and there’s a waiting pontoon outside if you need to hold position before entering.

Step-by-Step Guide to Using the Lock at Chichester Marina

1. Preparing to Enter the Lock

Before you approach, check the tide and your draft. If you’re unsure about conditions, you can contact the Chichester Marina lock office on VHF Channel 80 or call ahead on 01243 512731.

• Traffic Lights System:

  • Red = Stop and wait. The lock is in use.

  • Green = Proceed in or out of the lock.

• Listen for announcements: The marina staff often call boats forward when it's their turn, especially during busy periods.

  
  

Fenders and Lines: Ensure fenders are positioned on both sides of your yacht—locks can be crowded, and you may raft up alongside other boats. Prepare bow and stern lines for securing to the lock wall.

2. Entering the Lock

• When the light turns green, enter the lock slowly and under control. It’s good practice to keep a little distance from the boat ahead, as stopping space is limited.

• Follow marina staff instructions - they may ask you to move forward or adjust your position.

• Once inside, secure your lines to the floating pontoons along the lock walls. These rise and fall with the water, making it easy to hold position.

  
  

If rafting up to another yacht, use spring lines to keep movement under control.

3. While Inside the Lock

• If the water level needs adjusting, you’ll feel the boat rise or lower. This happens gradually, but keep hold of your lines and stay alert.

• The whole process takes just a few minutes. While you wait, enjoy the view—it's a great spot for watching local wildlife and other boats heading in and out.

• When the outer gates open, wait for clearance before departing—don’t rush out, especially if there’s an incoming vessel.

4. Exiting the Lock

• Once the gates open and you get the green light, ease out steadily—watch for boats entering and give them space.

• If heading into the marina, keep to dead slow speed (Chichester Marina has a 5-knot speed limit).

• If heading out into the harbour, check the tide and traffic before setting your course—this area can get busy, especially on weekends.

Tips for a Smooth Lock Transit

✅ Call ahead on VHF 80 – This helps marina staff coordinate lock movements and reduce waiting times.

✅ Be patient – During peak times, there may be a queue. Use the waiting pontoon if needed.

✅ Prepare your crew – Assign jobs before entering (e.g., who handles lines, who steers, who communicates).

✅ Use plenty of fenders – Boats can shift around inside the lock, especially if rafted up.

✅ Respect other boaters – Keep engine noise to a minimum and follow marina staff directions.
