INTRODUCTION
I’m going to assume that you’re already familiar with the sport of sailing, and that you’ve done a bit of racing too. This book is not aimed at the novice, although it is aimed at sailors who may never have sailed boats with asymmetric spinnakers before. It is hard to write a book that will appeal to all types of asymmetric sailor, but in this book you’ll discover I’ve interviewed a range of experts across a spectrum of sailing boats powered by asymmetric sails.
We’ve got tips on how to get the best out of:
small dinghies like the RS200 and RS400,
high performance skiffs such as 49ers and International 14s,
high performance multihulls such as Tornados and Formula 18 catamarans, and
sportsboats such as the Melges 24 and SB20.
Competitive racing in the Melges 24 fleet
Even if your particular boat isn’t directly covered in this book, I really hope you get some great tips from some of the experts we’ve gathered together, and that you’ll be able to carry over some of the hot tips into your own asymmetric sailing.
To sail successfully with an asymmetric spinnaker – or gennaker – requires you to start understanding what apparent wind is. Apparent wind is the wind that is generated by the boat moving forwards. It’s the same wind as you feel when you stick your hand out the window of a car when the car is moving, or it’s the wind in your face when you are cycling. It’s artificially generated wind, so you can feel apparent wind even when there is no true wind blowing at all.
Understanding the effect of apparent wind is crucial to sailing with asymmetric spinnakers, but it will also help improve your understanding of all types of sailing. It’s easy to think that, on a simple singlehanded boat like an Optimist, Topper or Laser, you run downwind just by presenting the sail to the wind and getting blown along, without any flow across the sail. Indeed that’s how most club sailors do run downwind in a Laser, but ask an Olympic standard sailor how they steer the Laser downwind, and they’re always doing angles, always with flow across the sail. They may be sailing a greater distance, but the increased efficiency by having flow across the sail more than makes up for the extra distance.
Harnessing apparent wind is the key to fast sailing in asymmetrics
Unlike a conventional, symmetric spinnaker or the mainsail on a singlehander, the asymmetric spinnaker cannot function without flow across the sail. It is absolutely reliant on wind blowing across the sail. But once you understand this, and that by combining the true wind with the apparent wind generated by your forward motion, then you will discover that you can achieve much greater boatspeeds. Many asymmetric dinghies and multihulls are capable of travelling at least as fast as wind speed and in some extreme cases such as the AC45 America’s Cup catamarans, travelling in excess of three times true windspeed is achievable.
One of the fun by-products of asymmetrics is that for the reasons just given, you can’t sail dead downwind – or at least it’s very slow and inefficient to do so. Because you want to maximise the apparent wind, you are always sailing angles downwind. Now the run starts to feel similar to an upwind leg, where any sailor knows that it is impossible to sail directly to the windward mark. Well, to some extent the same is true with an asymmetric boat. You have to sail angles, and that makes for a much more tactically interesting and challenging scenario.
AC45 America’s Cup catamarans can travel up to three times the speed of the wind
However, an asymmetric sail’s inability to sail dead downwind is not always a good thing. For example, if you are sailing in confined waters such as in a river or a stream, or you are running close to a shore against an adverse tide, you don’t want to have to drive out into stronger tide. So there are times when you notice the limitations of an asymmetric sail; but most of the time – and certainly in open water – the benefits of an asymmetric far out weigh the benefits of a symmetrical sail. With the asymmetric’s superior ability to generate its own wind, it encourages you to start looking for gusts, to look around for the strongest wind on the water. In a high performance boat, finding one knot more of true wind speed can help generate as much as two knots more of actual speed through the water.
So there are very good tactical and strategic reasons for sailing with an asymmetric. In many ways it makes the game more difficult and more challenging but, ultimately, more rewarding when you start to appreciate the tactical and strategic rules of asymmetric sailing.
One of the other benefits of the asymmetric is that, by and large, it is much easier to hoist, gybe and lower an asymmetric spinnaker than a conventional symmetrical spinnaker. It’s why, over the past ten years, the majority of beginners and family-oriented boats have come fitted with asymmetric spinnakers rather than anything else.
You have a bowsprit, sometimes fixed but quite often retractable. On many modern dinghies and catamarans, the gennaker halyard is also connected to a set of blocks which pull the bowsprit out at the same time. So one person pulls just one rope which launches the pole and hoists the sail in one movement. Compare this with a spinnaker where typically, on a two-person boat, it might be the helm who’s busy hoisting the spinnaker to the top of the mast while the crew is busy connecting one end of the pole to the guy, connecting the centre of the pole to the topping lift, and connecting the inboard end of the pole to the loop on the mast and then setting the spinnaker guy to the right place.
Some people enjoy the challenge of that and, for many sailors, it is one of the fun aspects of crewing. Some would argue that there is a lot of skill in how you get the best out of a spinnaker. The other side of it is that it is much easier to learn how to sail with a gennaker, because you just pull one rope and you’re away. In fact, one friend asked me how I could find enough information to fill a whole book on the subject. Yes, at its very simplest, you pull in a gennaker sheet until the sail stops flapping. That’s it! End of book!
Handling a gennaker is more straightforward than a traditional spinnaker

But the reality is that while gennakers are very forgiving sails to use, they also tend to be attached to boats that are very demanding to sail and race. This book is dedicated to helping you get to grips with the wider game of asymmetric sailing and racing. In the process of researching this subject I’ve spoken to some of the very best in the business. After almost 20 years of racing boats at world championship level – such as 49ers, International 14s and SB20s – I thought I knew most of what there was to know, but the asymmetric spinnaker is still a fairly new innovation in the history of sailing and we’re learning new tricks all the time. This book condenses the very best of what I’ve learned up to now. I hope you enjoy it, and that you find good, solid tips that you can apply to your own asymmetric sailing.
P.S. Throughout the book I refer to ‘asymmetric spinnakers’, ‘asymmetrics’, ‘gennakers’ (half genoa/half spinnaker), and ‘kites’. They are all one and the same thing. I try to avoid the term ‘spinnaker’, reserving that for conventional, symmetrically-shaped spinnakers.
It’s not within the scope of this book to ask you too many questions about what kind of boat you plan to sail. Because asymmetrics come in many different shapes and sizes, it’s difficult to hand out any specific advice, but I just want you to be sure that you’ve thought about the following factors:
Do you have the ability to sail the boat competently? Or, let’s put it another way, do you have the potential? Now, I know sailors in their 50s and 60s who handle the 18-foot Skiff and Musto Skiff very competently, and asymmetric boats don’t get much harder than that. Ian Renilson is still knocking in top ten finishes at Musto Skiff World Championships well into his 50s, although he is a former Contender World Champion. But Ian, like most other Musto Skiff sailors, did a lot of capsizing and swimming before he reached a certain level of competence. Are you prepared to do the same? If so, great! If not, then maybe you want something a bit more stable and easier to handle.
The 18-foot Skiff is great fun if you know what you’re doing, but it will bite you if you don’t!
Are you going to be sailing in a team boat? If so, how much can you rely on your team mate(s) to show up on a regular basis? Better to agree on the goals and the schedule for the year before you put down your hard cash on a boat.
Do you have the money, not just for the boat, but for its upkeep and maintenance? If you’re racing a boat where you expect to be doing a lot of capsizing and putting the equipment through quite a bit of abuse while you drag yourself up the learning curve, then it may be better to do your learning on a well-sorted secondhand boat. Even better if you can get the seller to throw in a day’s coaching to help you get to grips with the basics. It’s also a great way to check that the boat you’re buying is working properly and that you haven’t been sold a pup.
To sail a high-performance boat well, team mates need to share the same goals and ambitions
Is there a local fleet at a nearby sailing club, or a good racing circuit that you can get involved in? While any new boat is exciting to sail initially, the novelty will eventually wear off. But it’s the racing and the camaraderie that will keep you interested. So give this factor some serious thought before deciding which boat to sail.
One of the difficult things to get your head around when you’re discovering asymmetric sailing for the first time is the idea that if you want to get downwind you need to head up first. In planing conditions, if you want to get the bow pointing as low as possible downwind and make the best VMG (Velocity Made Good) to the next mark at the bottom of the course, then the way to do that initially is actually to head up as high away from the wind as you can. Unless you do this, you’re not really apparent wind sailing, you are just wafting downwind with the breeze and the gennaker will be caught behind the mainsail and the jib, and will never get a chance to fill properly. So, if you’re new to this, the first thing to do is to head up perhaps more than you think you need to, and get the air flowing across the gennaker from luff to leech and drafting out the back of the sail.
To create your apparent wind, first you need to luff up to build the speed
Once you do that, the apparent wind will kick in and start building on itself. As the apparent wind increases, it also moves forward and you need to sheet on the gennaker and the mainsail to compensate. And, if it’s windy, you’ll need to hike out as hard as possible to counteract the increase in power. In strong winds you’ll find those who hike out hardest actually end up sailing lowest and deepest towards the leeward mark. At first it doesn’t seem to make sense. After all, in most sailing you sit in to sail lower, but not in an asymmetric when you’ve got the power of apparent wind on your side.
In light to medium airs, when there isn’t enough wind to get the boat planing, then it’s about sailing as low as possible before you experience a massive drop-off in flow across the sails. Where sailing dead downwind is an option in non-asymmetric boats, it’s never an option with asymmetrics. You always need to sail angles downwind, and in light to medium conditions the trick is finding out just how low you can go.
MELGES 24s trying to ‘soak’ low in non-planing conditions
On a keelboat you may have electronic GPS equipment which you can use to help determine your best VMG downwind. On a dinghy or a small multihull, you don’t have that luxury so you have to develop a feel for when you think the boat is travelling at the optimum VMG downwind. Quite often you can’t really work this out until you start racing other boats, when you can compare yourself to others nearby. In marginal planing conditions you’ll find there are those who like pushing high and sailing extra distance for the extra speed, while there are those who like really running deep and going slower, but sailing a shorter distance to the next mark.
Both those extremes have their place, and sometimes it pays to do a little bit of each. A lot of the time, the decision that you make about whether to sail in high, medium or low mode is based on the tactics of where the boats around you are, and where you’re aiming for next. It is also based on where you think the best breeze is. Sometimes, when you’re in a nice but narrow line of breeze, it pays to sail low to stay in it as long as possible. The temptation can be to head up, get on the plane and sail really fast – only to sail yourself out of the breeze line.
Two International 14s sailing in very different modes
So it’s really important to be able to sail in all these modes. We’ll address this in Chapter 7, Boat Speed. And it’s also important to know how and when to apply these modes on the race course, which we’ll address in Chapter 8, Racing: Strategy and Tactics.
If you’re using a boat with a spinnaker chute then it’s the crew who tends to do all the hoisting in a two-handed boat. The helm’s chief job is to steer the boat so that it’s upright and stable and gives the crew plenty of opportunity to hoist the spinnaker without worrying about helping to keep the boat upright.
With a boat with a chute, you might want to share out the job of hoisting the gennaker, as there are more ropes to pull. So, for example, in the Laser 5000, a typical routine would be for the helm to pull up the spinnaker halyard while the crew pulls out the pole and the tack line. So it’s a matter of dividing up the workflow in such a way that you get your gennaker up and pulling in the shortest amount of time after the windward mark.
Despite the enormous sail, the 18-foot skiff gennaker is launched and retrieved into a bag
In a boat with three or more crew, such as a Melges 24 or SB20, then you can divide up the workload even more. So in the case of a three-person SB20, the typical work pattern would be:
Helm continues to steer while taking the mainsheet from the middle man.
Forward hand goes to leeward to prepare the gennaker by opening up the bag. He then pulls out the bowsprit. At the helmsman’s command the forward hand hoists the gennaker and cleats it off.
While the forward hand is hoisting the gennaker, the middle man pulls the tack line until the tack reaches the end of the bowsprit. He then moves straight to the kite sheet (taking it from the helm if the helm has already picked it up) and gets the kite set while the forward hand sets the jib and tidies the cockpit and the kite halyard in particular.
When you rig the gennaker, make sure you get it right before you go afloat! I can guarantee that at some point in your asymmetric sailing career, you will forget this simple advice. Some lessons you have to learn for yourself, and believe me, there are few more embarrassing or painful that having to re-rig the gennaker out on the water. It’s not easy, and it often results in a capsize. You can remind me of this fact the next time you see me up on the foredeck of my Musto Skiff!
Have a set routine for rigging the boat, and you’ll avoid foul-ups on the water
If you launch from bags, as with a B14 or an 18-foot Skiff, then at least all you have to do is tie three corners to the correct rope. But for the sake of simplicity and avoiding silly errors, make sure you write ‘Tack’, ‘Clew’ and ‘Head’ on the correct corners. And I’d tie them on in that order too, although this isn’t too critical. One reason for doing this is for rigging up on a windy day, when you don’t want to have the kite blowing around the dinghy park and potentially capsizing your boat. Having the names written on the corners means you can have the kite stuffed in the bag and still tie on the corners without exposing too much sail to the wind.
Now, if you launch from a chute, which is the norm for most asymmetric dinghies and small catamarans, then you have the added complication of a retrieval line, which is basically the other end of the halyard because it’s one continuous line. The retrieval line makes it much more possible to create tangles and to get it wrong if you’re not careful with your rigging procedure. It also makes it much harder to re-rig it on the water if you get it wrong, so it’s particularly important to make sure that you’ve got your rigging correct with a chute style of boat.
There are different ways of doing it, but my favourite way of rigging a gennaker on an International 14 or a 49er for example, is to:
tie the tack first, with the bowsprit retracted into the boat;
loop the kite sheets through the clew and reeve the port sheet through the port-hand ratchet block on the boat;
pull the foot of the sail tight so that you know there’s no tangle. I do this on the port side of the boat on the 14 because this is the side where the kite hoists from;
take the retrieval line (already threaded through the spinnaker sock) and run it underneath the foot of the sail, and then run it through the bottom retrieval patch near the foot;
depending on whether you’ve got a one-, two- or three-patch retrieval system on your kite, make sure that the halyard is going through all the correct patches, and then tie the end of the retrieval line off to the top retrieval patch;
take the other gennaker sheet that runs around the starboard side of the boat, take this starting from the clew, and run it along the side of the boat
inside
the gennaker, making sure it goes over the
top
of the retrieval line, runs around the forestay and then back down the other side of the boat through the ratchet block;
tie off your gennaker sheets in the middle of the cockpit, and
tie the halyard on to the head of the kite.
The reason for attaching the halyard last is so that if the wind does catch the sail while you’re rigging it, you’re not going to get it filling and flying out from the top of the mast, potentially capsizing the boat and causing damage while you are on the shore. So the gennaker halyard is always the last thing to be tied on and then you’re ready to fully retract the kite into the chute and that should make sure that you don’t have any tangles. If it’s windy you can pull most of the sail into the chute before you attach the halyard.
If the winds are light, and you don’t think it’s going to cause any harm to the boat, then take the opportunity to double check your rigging. Hoist the gennaker to the top of the mast and make sure that all the sheets are running clear. If the winds are strong, the chances are you won’t get an opportunity to do that, which means that when you get out on the race course, unless it really is extremely windy, you want to check that you rigged the gennaker correctly as early as possible before the start of the race. If by any chance you have made a mistake, you at least give yourself the maximum time to put it right. But good luck!
