Keel stepped mast, or not?!

mast through deck vs. mast on deck: which mast arrangement suits you?

As an Elan Yachts dealer in Belgium and the Netherlands, we often get questions about the technical aspects of our yachts. One of the questions often asked is about mast positioning: What is the difference between a through-deck mast (keel supported) and a deck-mounted mast (deck supported)? And what does this mean for a yacht's performance and annual maintenance? In this article, we'll take you through a bit of the technical aspects of mast arrangements and how these choices are reflected in our Elan models.

What is a keel stepped mast?

A keel stepped mast runs through the deck and rests directly on the yacht's keel. This means that the mast force is transferred directly to the keel and hull. This configuration is often seen on yachts designed for higher sailing performance and sail optimization.

Advantages:

• Better force distribution: Because the mast force rests directly on the keel, the load is more evenly distributed. This ensures a robust and sturdy construction.
• Better performance: A through deck mast is generally stiffer and provides more efficient sail trim. This makes it ideal for racing sailors or demanding cruisers.
• Greater trimming capabilities: Sailors often have more control over mast bending and can adjust the rig more precisely.

Disadvantages:

• More maintenance: As the mast passes through the deck, water infiltration can occur around the mast collar or around the electrical wiring. Regular inspection and sealing is important.
• More complex installation: Installation and removal of a through deck mast requires more precision and is slightly more time-consuming.

What is a deck-mounted mast?

A deck-mounted mast rests on a mast foot on the deck and the down force is directed to the keel via a compression post. This configuration is often chosen for cruisers because of its ease of use and maintenance.

Advantages:

• Easier maintenance: Because the mast rests on the deck, you need pay virtually no attention to leaks at the grommet.
• Lighter construction: The mast profile is shorter and therefore lighter and cheaper.
• Easier installation: A deck-mounted mast is quicker to install and remove, which is convenient for winter storage or maintenance.

Disadvantages:

• Limited force distribution: The forces from the mast must be transferred to the keel through the compression post. This can create more load at specific points (point load).
• Less trimming capabilities: Although a deck-mounted mast is perfect for cruising, the rigidity and control of the mast is less refined than with a through-mounted mast.

Elan Yachts and mast arrangements: a choice for every style of sailing

At Elan Yachts, we understand that every sailor has different priorities. That's why our yachts offer solutions for both demanding cruisers and sporty competitive sailors.

• Elan E-Line
  The E-Line models are designed with performance cruising in mind. With this line, a through deck mast is the default choice, as sailors seeking high performance and precise sail adjustments benefit from the stiffness and power distribution.
• Elan Impression Line
  For comfortable cruising with family or friends, the Impression line offers a deck support mast. This arrangement suits sailors who prefer simplicity and ease of maintenance without compromising on reliability and ease of sailing.
• Elan GT Line
  The Gran Turismo line combines the best of both worlds. For sailors who want both comfort and performance, Elan offers configuration options on the GT6 that allow you to tailor the mast setup to your personal preferences.

Which mast setup is right for you?

When choosing between a through-deck and deck-mounted mast, it's all about your sailing style, needs and priorities. Whether you choose precise performance or ease of maintenance, Elan Yachts offers yachts that match and even exceed your expectations.
