Strategy and Tactic

Philipp and Julian Autenrieth: "The best tactic and strategy decide the outcome, while the boat and the conditions are more or less the same for everyone.  Whoever can make the best out of these conditions, wins."

Strategy and Tactic - Chance and Risk - Gain and Loss

Jochen at fair boot 2017

Jochen Schümann, a prominent visitor at the"boot 2017" in Düsseldorf and much sought after interview guest, took time to visit "Tactical Sailing" and get the latest information regarding the program that he and our Tactical Sailing Team had discussed last year. Our discussion had covered a very important aspect in regatta sailing, namely, the relevance of "Reward and Risk" and "Gain and Loss" situations in competitions. "This topic must be structured" was Jochen's professional opinion of the complexity of this problem. Thereupon our Tactical Sailing Team began analysing all written articles on this subject that could enable them to program a corresponding simulation. We were delighted that we could present Jochen with our first results of this highly complex topic. For Jochen the following aspects were of main importance:
- the ability to read and evaluate the wind on the regatta field.
- the distance (%) to the layline determines the reward and risk of windshifts.
We were pleased when Christian "Kicker" Schäfer from Bavarian Yacht Club (BYC) joined us for further discussion regarding our "Reward and Risk" simulation. It was immensely helpful that these two highly professional sailors not only provided us with a lot of new ideas, but also motivated and inspired us to implement the perfect presentation of "Reward and Risk" in our "Tactical Sailing" program. In Jochen Schümann's detailed interview in the financial magazine "Capital" from 26.11.2014 "What managers can learn from athletes", the topic of chance and risk plays a decisive role, see below.

“Through the physics of sailing you are permanently compelled to make clear decisions"

The "safety diamond"

The latest version of the "Tactical Sailing Toolbox" includes not only the existing exercises for beginners but also "Gain and Risk" for experts. Here the sailor must decide at the starting line whether to take the left or right side of the regatta field.
Jochen Schuemann said in an interview: "Through the physics of sailing you are permanently compelled to make clear decisions. The aim of the race is obvious. Upwind brings you to the first mark which you also want to be first to reach. Fundamentally you must decide at the beginning which direction you are going to tack. This is a completely strategical question. Remembering you are manoeuvring under permanently changing conditions: wind direction, wind force and currents. Every moment brings new decisions to be made: do I hold course, veer off, or try a completely different direction?" (Capital, 26.11.2014). There is absolutely no reliability by choosing one direction or the other. You cannot calculate or work out the ideal course in advance, but with mental training you can prepare your decisions. The new version of the "Toolbox" with its' special simulation "Gain and Risk", proves to be most helpful. For example: when you double the distance between you and your opponent, then your advantage is also doubled.
A useful aid for estimating the "Risk" is the "safety diamond". This shows the tactical decision boundary line and should not be crossed. This ensures that the "Risk" has set limits and should not be unnecessarily overstepped.

Gain and Loss

Rotating wind ladder

Another aid for assessing your gain or loss through oscillating wind is the "rotating wind ladder". This shows any changes in the distance between you and your opponent, namely: are you now sailing ahead or behind your opponent? In particular, on the way to the finish line are many tactically deciding factors which you can reassess or correct to gain or win.

Simulation Gain and Loss
Simulation delivers important factors and is a decision-making aid for reacting with wind. By using the shifting wind (Gain), you shorten your course to the windward mark. By ignoring it (Loss), you unnecessarily lengthen your course. The new Simulation estimates immediately the "sailed course", as well as the theoretical "still to be sailed course". We also simulate your tactical options so you can analyse various alternative decisions. In addition we provide you with a second competitive boat to match against as your opponent. This simulation is shown as a line of distance of the boats painted on the water as in the America's Cup TV coverage.

"This Match Race on the computer has huge potential."

Jochen & Marvin

In an interview with Tactical Sailing, Jochen expressed his first impressions of the game. “I am actually not a computer game player, but this match race on the computer has a lot of potential, for larger Match Race yachts, too. The Optis were really fast when shooting head to wind, but in the wind, immediately stood still. With larger yachts with their high net weight, you need to pay more attention to inertia when shooting head to wind. Therefore, this game would be really realistic for training.” We went to work, starting with the polar diagrams of a TP 52, and integrated the well-known TP 52 match race yachts in our program. Our number 1 is most definitely Jochen Schumann’s yacht, "All4ONE". See more about the project "All4ONE".

Jochen Schumann vs. Marvin Frisch in a Match Race

During the previous 2012 Boat Show there were multiple premieres of every sense simultaneously taking place at the “Tactical Sailing”: Boat Against Boat Opti-Stand. One was the Match Race between the arguably most well-known German sailor, Jochen Schumann, who until that moment had never before used a computer to control a boat, and Marvin Frisch, the German Champion in Opti 2011. Match Racing is a game for experts, which includes an exciting but tricky countdown before the starting gun. As an inexperienced PC-player, Jochen received a short technical introduction on the precision of controlling boats from his adversary, Marvin, before heading off to the starting line.

Fighting to get the best place on the starting line, Jochen showed his many years of experience by analyzing the wind at the starting line, while watching the actions of his opponent in order to tactically plan out the best route possible. However, Marvin would not be intimidated. Instead, he demonstrated his strong nerves and challenged Jochen to a bitter fight at the starting line. The outcome: An early start (OCS) for both Jochen and Marvin!

It was a pleasure for all the visitors at the Opti-Stand to watch both sailors in full concentration steer their boats. We’d like to congratulate Jochen for confidently tackling his first computer regatta. Although he had problems with "sailing without the wind on his neck", he preformed exceedingly well. Jochen and Marvin definitely didn't make it easy on one another, but rather had their fun at fighting for each and every centimeter.
