Firstly let us remind the main benefit of hiking flat out. IT IS FASTER, you might ask yourself how much faster, below you can see a graph of a boat hiking flat out periodically, the peaks are top speed while hiking flat out, the rest is regular hiking, the average speed difference can reach as much as 2 knots which accumulates to over 20% in boat speed. (This boat has been doing a 30 seconds flat out 30 seconds regular hiking)
Though we have been discussing much about downwind sailing and ways to go fast, based on our experience the big money in sailing is on the runs, so there is always room for more gains to be made.
When we go sailing, the boat may just push water out of the way (usually called displacement mode), ride on top of its own bow wave (planing) or foil. This week we look at how water resistance effects boatspeed, and what we can do to minimise this resistance.
The sailing world is going foiling mad. Time alone will tell whether it's a good thing or not, but what we can say is that it's fun and fast, and very different in feeling. What is the same for the sailor is that we need to understand a far greater range of sail settings in order to optimise the performances of these boats.
As boat speeds increase, the wisdom of conventional tactics become far less relevant that they have ever been. For example, in a fast boat, covering one of the opposition can create an opening for 10 boats to get past you. Not what is needed…..
The evolution of skiffs and foils have generated the necessity for the evolution of the skills of pressure hunting.
A major source of beginning to understand tactics is dealt with by Toplevel sailing as tactics for the first half of the beat (when the boats are diverging into a wider area, as against tactics when the boats are converging into the tiny area around the mark.
The movement of water over a course area is rarely uniform. Because of this factor the racing sailor has to have an understanding of where currents are at their maximum, how this helps or obstructs progress and where a current will take you sideways away from the mark, or sideways towards the mark. Where possible, using current in different areas to enhance the speed around the course can be much more rewarding than finding a lot of boat speed through increased wind speed.
