Knowing your boat and how to trim your sails to best achieve the 3 Modes of upwind sailing are crucial skills to have for the best performance of your boat.<\/p>\n

For the Racer<\/strong><\/p>\n

Being able to effectively \u2018mode\u2019 your boat at any time on the race course can greatly improve your racing performance. Choosing which mode to use depends on a number of factors but is generally a combination of wind, tide, opposition and where you are on the race course.
Sail trim is pivotal to the modes and before focussing on the modes themselves I strongly encourage you to have a thorough read of my Sail Trim Notes. Adapt them to your boat and make sure everyone in the team is familiar with how to best trim your sails.
In executing the trim required to achieve the maximum potential from each mode, communication is critical hence the importance of the \u2018trim cycle\u2019 to be sure the flow of information between the team is contributing to the best performance.<\/p>\n

For the Cruiser<\/strong><\/p>\n

Being able to mode your boat while passage sailing can greatly improve the efficiency of your passage making and navigating around obstacles and obstructions much more simple. It will also make your boat easier to sail in those passages by reducing the tacks and gybes executed and limit your sail handling.
By efficiently and effectively configuring your boat you can reduce your passage times and make your passage more pleasurable. By applying the tips and tricks in my sail trim notes you can also make your boat handle better and increase the overall efficiency of your passage sailing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Reduction of angle of attack by pointing your boat closer to the wind:<\/p>

Less lift (sails)
More leeway (less keel grip)
Going slower
Reduction in heel angle\/power<\/p>

When do I use it?<\/strong>
Holding a lane off the start or a lee bow
Making life hard for your opponent(s)
Controlling your opponent(s)
Options by being able keep sailing in clean air
Staying in phase where height is your friend
To make a mark when marginal lay line<\/p>

How do I achieve it?<\/strong>
Pull your sails on tighter (sheet tension) reducing twist
Pull your sails closer to centre line (sheeting angle) using jib tracks, inhauler, traveller
Reduce entry angle (halyard\/cunningham)
Steer the boat in a feathered mode
Reduce righting moment (move crew weight)<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Velocity Made Good<\/p>

The best VMG for your boat
Balance of good height and speed
Fastest combination of height and speed
Optimum heel angle\/power<\/p>

When do I use it?<\/strong>
Most of the time
Sailing in clear air
Options open
Staying in phase<\/p>

How do I achieve it?<\/strong>
