Sailing ships were largely dominated by a common concept:  the mast is always on centerline.  The sails are always on centerline.  But a new yacht concept named Ankida offers a new option.

Sail Plan Features

Let us review a few of the fascinating features for the sail plan alone

  1. Sails are not on centerline.
  2. Main sail and “jib” are both on booms with sheets
  3. Full height vertical battens.
  4. Spinaker stores nicely into a package at the top of the mast.
  5. Sails can go wing on wing with an additional spinaker deployed.
  6. Sails shift forward or aft of the mast depending on tack to avoid shadowing each other.

Now, I am sure there are many practical naval architects out there who will point out the complexity of this system.  And I will agree that the complexity is a concern.  But lets not criticize too quickly.  We need to give credit to the inventive people at Lila-Lou for creating this concept.

Yacht Features

And the innovation doesn’t stop with the sail plan.  The yacht itself has some very interesting features.

  1. Two vertical axis wind turbines on the top of the mast provide much of the electrical needs for the vessel.
  2. The keel bulb hangs on a horizontal track and shifts depending on vessel heel.  Excellent if you don’t want to heel too much when sailing.
  3. The bottom horizontal track also has two bilge keels.  These keels are much farther than the ship’s center of gravity than you normally find.  They will provide exceptional roll damping.
  4. Splitting the mast onto each side of the vessel provides a clear load path for vessel heel forces produced from the sails.  The forces travel straight down the masts and balance out with the keel.  Very little hull structure is involved.  Means less hull reinforcement, and less risk of rupturing the hull if the mast should break.
  5. Splitting the mast also keeps the deck area largely clear, allowing more flexibility in deck arrangements.


The first video is beautiful introduction to Ankida and shows how it works under various points of sail.


The second video provides a better breakdown of Ankida’s components and how they get used on various points of sail.



Ankida has me excited because I see applications with this mast on larger commercial vessels.  The vertical axis wind turbines can be scaled up to use the entire mast height and generate far more electricity for propulsion.  And the mast landing on the side provides less interference for cargo unloading operations.

Now don’t go out and order an Ankida cargo vessel.  Certainly, there would be plenty of challenges.  But this post is about the concept.  And the possibilities of this concept are truly exciting.
