How to Anchor a Boat with MaxSea TimeZero

Experienced sailors often say that mooring is the most difficult part of sailing. This week, MaxSea partner Leon Schulz talks to us about how to anchor a boat, using MaxSea TimeZero.

Leon outlines the steps to take for a perfect mooring. His boat is equipped with a fully-integrated system: MaxSea TimeZero PLOT, a Furuno BBDS1 sounder, and a Furuno NavNet TZtouch.

How to Anchor a Boat

Leon Schulz’ boat the Regina Laska

  • Understand the sea-floor. Navigate around the anchorage area many times. This is done to record bathymetric information so you know what kind of sea-floor you’re dealing with. To record this data, I use my MaxSea TimeZero PLOT, integrated with a Furuno BBDS1 Sounder.

Anchoring a boat with Furuno BBDS1

The BBDS1 sounder collects and sends bottom classification data to MaxSea TimeZero software. I can also share this new data-rich bathy chart with the integrated Furuno NavNet TZtouch system. Sand or clay is best for anchoring.

  • Check tidal range by displaying tidal data in MaxSea TimeZero. This is a really important step to know how much your boat will be raised or lowered by the tide, or vice versa.

How to anchor a boat with tidal data

You don’t want the boat’s keel to hit the ground during the night, just because the water has disappeared from under the boat. You must also avoid having the boat’s anchor break loose because the boat is suddenly 3 or more meters higher water than when it arrived!

  •  Calculate your desired minimum depth based on my boat’s draught + safety distance under the keel + allowance for tidal changes. Try to find a spot where the boat can swing freely in all directions according to changes in the wind or the tidal current.
  • Take a last look at the Furuno BBDS1 sounder to check the depth and soil conditions and to see if the boat is in the tidal flow or in an area of strong wind and bring the boat to a complete standstill.
  • Lower your anchor slowly until it reaches the ground. You can check the markings on the chain or just listen to how the anchor runs more smoothly when it has reached the bottom.
  • Give the signal to the helmsman to reverse the boat slowly while letting out the chain. At a ratio of 1:4 to 1:5 (from the highest tides expected), stop the windlass.
  • Wait until the anchor sets and the boat turns into the wind. Then it’s time to stretch the chain by reversing the gear carefully. Do so cautiously, so that there is no residue in the chain.
  • Once the engine is stopped, set the snubber. This is the piece of rope that is hung with a claw hook into the chain and relieved with the help of a jerk. This also makes the disturbing noise disappear from the chain rubbing against the bow roller.
  • In windy conditions, put a mooring sail aft, so the bow always points into the wind.

The advantage of MaxSea TimeZero is that you can so easily switch charts. So I often use raster maps at anchor, because there is a lot more information that are interesting for the anchors located. For example, the underwater cable at Iona (see image below).

Anchoring a boat with raster charts

Anchoring the boat off Iona, Scotland

Even small anchors are located on the raster maps. In comparison, the vector charts give less information about the anchorage.

Now it’s done, you can sleep soundly, even if the wind should freshen up in the night or the wind direction changes.

Diary of IMERPOL’s Polar Navigation

Joëlle & Janusz Kurbiel are members of the polar navigation expedition group IMERPOL and use MaxSea TimeZero software on board. They are currently in Newfoundland, heading northwards. Here is an update of their polar experiences:

Waiting for the ice to melt:

We are still in Newfoundland but can not go further north because we are currently blocked by ice. The icebergs are unusually large for the season in this specific location! We are therefore taking this opportunity to sail between the islands of the north coast to perform various tests.

Cold Weather Sailing Guide

Carpet in the propellers!

Everything is going well except for one incident we experienced when launching: the port staff had used pieces of  carpet on top of the lift straps to avoid damaging the hull as it was being lowered into the water. However, these pieces of carpet were not securely attached and ended up getting caught in the propellers! This is how they looked:

Polar navigation Carpet stuck in PropellersThis stopped the engine instantly. We needed to lift the boat out of the water again and painstakingly cut out all the stuff that was caught so tightly in the blades.

Polar navigation IMERPOL

Since then, Janusz has been hearing a strange noise from the engine. Hopefully the shaft and propeller were not distorted, this would make us totally ineffective… we’ll have to wait and see.

Polar navigation Newfoundland Map

Moving on

A storm from the southwest is forecast in a few days. This should clear the ice away allowing us to move a little further.


Thanks Joelle and Janusz! We wish you the best of luck for the rest of your expedition.

We will keep you updated on their travels.

Sailing Europe – the Top 5 Destinations this Summer

Going on a sailing trip this summer? Luckily, there are plenty of great destinations in this part of the world – if you’re in Europe that is! Here are five of our top picks for sailing Europe.

5. The Greek Islands

This is a very popular destination for renting chartered sail boats, and you will certainly enjoy the warm waters and beautiful views. Sail from Santorini to Mykonos to experience idyllic island scenery and Mediterranean charm. Renting a boat with a few friends can be a good choice if you’re on a budget, and no need to stay in hotels at night.

4. Croatia

Croatia has over 1000 islands in the crystal clear seas of the Adriatic, so plenty of beauty is waiting to be explored. Spend your summer taking in the views from the boat, or explore the many beautiful coastal towns, such as Split, Dubrovnik, or Makarska.

The Dubrovnik Coast

3. Ireland

If warm weather is what you’re looking for, this may not be a safe bet. However, the port of Galway in the west of Ireland is beautiful and offers rich history and character. With an oyster festival and the finale to the prestigious Volvo Ocean Race taking place here every summer, there are plenty of activities to keep you busy.

2. Slovenia

Slovenia offers easy access to the Adriatic Sea, and is becoming a hotspot for yachts. Visit the beautiful Bay of Piran, or the towns of Portorož, Izola or Koper, to explore some beautiful ports and marinas.

The Slovenian Coast

1. French Riviera

As MaxSea is a French company, we are slightly biased, but most sailors will agree that the French Riviera is a particularly beautiful spot to visit in Europe!

The French Riviera stretches along the Côte d’Azur, and features an all-star cast of sailing hubs, such as Cannes, Antibes, Saint Tropez and Monaco.

Wherever you end up going this summer, get there safely with MaxSea TimeZero navigation software.
