How to Windsurf – the Tack on a Sinker Board

One of the most elegant maneuvers if done right is the fast tack. A smoothly carried out tack on a sinker board with an upright body position throughout the move is pretty impressive, especially in waves. When the pros do it, it looks like they teleport onto the other side in the blink of an eye. Let’s have a look at how it is done.


First off, I think it is important to remember that this is a move that we should tackle step by step. Just because you are able to plane and gybe on an 80 litre board, doesn’t mean that you should be trying to learn the fast tack on it. Start with bigger boards and move down. It may seem like a nuisance to have to go back to 120 litres on a day that you would be able to sail on 100 litres but trust me, the extra volume will forgive you a lot more of the many mistakes and missteps that you are going to undoubtedly make during the first 50 attempts. Only once you have it down on bigger boards does it make sense to master it on the next size down. This small piece of advice, when followed, will save you a lot of frustration. Trust me.

That’s my two cents out of the way, let’s talk technique.


We are trying to get through the wind on a board that sinks when not planing. This means that we must do most of the footwork while we are planing. Make sense? Good, let’s move on.

Luffing up

At speed we will move the front hand close to the mast and the front foot in front of the mast foot. Just like with the beginner board tack, we want to set ourselves up so that the amount that our feet have to move is as small as possible. The more steps we need and the further we need to move our feet, the more time we will require. Time during which the board slows down and sinks.
Make sure that your weight is over the front foot. As we turn into the wind we will be trapped on the old side of the sail if the weight is on the back foot. Keeping the weight on the front foot will keep the board horizontal (so we don’t lose speed due to the back of the board being pushed down) and it allows our feet to change position under our body. If our body weight is offset from where our feet hold us over the board, we will topple over as soon as we try to move our feet.

Get on the other side of the sail

Before the board is in the wind, jump on the other side, the back foot replacing the front foot and the hands getting on the other side of the boom as quickly as possible (it is important to keep the clew close to the water so that the feet have more space to move).
Speed is key here. The faster we get on the other side, the more steady the board will remain. When I get asked about the secret of the fast tack I always reply: Fast feet!

Small tip:

In choppy water or waves, be sure to choose the moment on the top of the wave or chop. This will provide you with a moment of weightlessness during which you can move on to the other side of the sail without having your board be pushed around under you.

Continue a little on the lee side

We can remain on the lee side for a few metres, mainly to get our balance sorted out. This time frame will get reduced naturaly as we get better. Although I admit that one of the things I find elegant about the fast tack is continuing on the lee side for a second or so before going through the wind but that’s just my opinion.
To achieve this it is important to keep the front arm straight and controlling the power that is pushing us up only with the back hand. If we need more power we can always bring the front arm closer and bend our knees but it is very hard to get the sail down again once we are vertical on the board with the sail pushing against us horizontally as opposed to us laying on the sail and the wind pushing us upwards. The second scenario provides us with a greater buffer to react to gusts, etc.

Turn through the wind

Push with the back hand while keeping the sail low (try to push the clew along the water surface. If the sail is pushed into the wind with the sail too high we will just bear away and get pushed over by the sail.

Bear away on the new side

As the board turns through the wind we can bring the mast forward and sheet in on our side to bear away on the new tack

Start planing again

Be ready to sheet in and lean back. As the board bears away, push with the front foot into the board and pull the back of the board under your body with the back foot. Once it is on a broad reach get the board planing again.

Sinker board tack

To recap.

  • Start by planing
  • Luff up into the wind with the front foot in front of the mast foot and the front hand close to the mast
  • Keep your weight over the front foot
  • Get on the other side of the sail
  • Make sure you are stable on the new side by controlling the power with the back hand and keeping the front arm straight
  • Turn through the wind by pushing the clew towards the wind while keeping it close to the water
  • Bring the mast over the front of the board and sheet in to bear away on the new side
  • Push into the board with the front foot and pull the back foot under your body to start planing again

How to Tack

How to Tack

Being able to turn around quickly without falling in is a pretty useful thing to know how to do in windsurfing. However, I would like to note that it is not essential to know in the initial stages of windsurfing. “Why?” you may ask. Well, basically, the way we tack and gybe with big boards and small sails is different to the way we tack and jybe with small boards and big sails and until then we can simply use the basic windsurf turn. With big boards we are going to rely a lot on the spare volume that allows us to float and have stability even when the board is not moving. This is not going to be possible when windsurfing with small boards. These boards won’t have any reserve buoyancy and so won’t float when standing still which means that the technique in tackng and jybing is very different. That being said, knowing how to tack is a useful thing to know and a good thing to practice as we solidify the foundations of our windsurfing technique. After all, it all builds the sensitivity required for the sport.

So let’s get to it. Before we start we want to keep in mind that throughout the whole manoeuvre we want to keep wind power in the sail. We want to try to keep equilibrium not by balancing on the board but by using the wind in the sail. To do this we want to keep one hand on the boom at all times, before and after changing sides. Let´s have at it step by step:

  1. From the normal sailing position (1.) we put the front hand on the mast just below the boom and the front foot moves to just in front of the mast. As we do this the sail is lowered to the back of the board (or away from the wind) (2.) See why in the post on steering. Important to note, we move and keep our weight on the front foot throughout the whole manoeuvre.
  2. The board starts turning into the wind. We continue holding the foot and hand positions until the sail is on the new side. A good indicator is when the foot of the sail (the lower edge of the sail) is touching our shin (3.).
  3. Right then we need quick feet. The longer we take to get from one side with pressure in the sail to the other with pressure on the new side, the more likely it is that we lose balance and fall in.
  4. We bring the back foot forward to where the front foot was. At the same time the back hand replaces the front hand on the mast. We keep the sail low all the way until this moment (4.).
  5. Now we simultaneously move the previously front foot to the back and bring the mast forward to bear away from the wind (5.). The weight is transferred on to the foot that is now in front of the mast.
  6. The board will bear away. As it does this we must start to transfer the weight on to the new back foot gradually and open the sail (sheet out) gradually so that the wind doesn’t build up too much pressure in the sail as we bear away.
