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.
Tiller Talk, Boat Talk
We sail, we want to sail fast, and the only thing stopping us sailing faster is drag. Drag comes in two main forms. The hull and centreboards creates drag in the water. The Rig creates drag through the air. Water being 1,000 times denser than air by a lot, the drag created by the hull... Continue Reading →
For most sailing boats the ability to control the power is made by bending or straightening the mast, as the mast bends it flattens the fabric of the sail, moving the center of effort down and opening the leech, the opposite happens when straightening the mast.
Preparing for Success
Nobody tells you when you're growing up that "winning" and "success" come at a cost. At world level the cost is many times that which anyone outside top sport can imagine. It involves the sacrifice of dedication, not for a month or a year, but four years plus to reach anywhere near potential. The cost... Continue Reading →
Downwind – Flat or Kite?
An important skill in downwind sailing is prioritizing weather to sail the boat flat or healed to windward by the lee referred to as kiting, Sailing by the lee means that the air is flowing into the sail from the leech towards the mast as opposed to normal sailing when the air is flowing from the mast towards the leech of the sail
The evolution of skiffs and foils have generated the necessity for the evolution of the skills of pressure hunting.
Successful Sailing Club Coaching Whether or not we are engaged in sailing clubs, we all need to recognize the amazing value a sailing club brings to our sport, and the diversity which often exists within their activities. Clubs are thought of as places where people who sail congregate to share their mutual enjoyment of our... Continue Reading →
Speed and DRAG
Speed and DRAG Boats are designed to go through the water, and over the past 70 years have been designed to ride ON the water. Over the past 10 years plus they’ve also been designed to fly over the water. These hull designs are termed as displacement (through the water), planing (riding on the water)... Continue Reading →
Gybing a Laser Most sailors will gybe an average of 3-4 times per race, so the toll a bad gybe might take on your overall result is usually minor to an overall performance, however there are gains to be made by performing a good gybe. What are the reasons for gybing? In a laser heading... Continue Reading →
Go fast or go home! The angle of sailing relative to the wind has a major influence on boat speed; and even more of an influence in catamarans. Faster sailing boats generate apparent wind, the faster the boat moves, the more apparent wind it will generate. Speed allows foils to work better, and consequently to... Continue Reading →
