GUIDELINES FOR BUILDING UP YOUR PERSONAL SAIL QUIVERUpdated a year ago

First you should define the biggest and smallest sail size you will need to cover all wind speeds you wanna sail in. This mainly depends on your body weight (see above).
Let’s take an “average” 75 kg sailor and let’s assume this guy wants to sail in “any kind” of wind.
- The biggest sail size this guy would need is something like a 7.3. With a capable 100-120 litre Freeride board this size would get him planning in approx. 8-10 knots.
- His smallest size would then be a 3.7. On a 70-80 litre (Free)Wave board our guy should be fine up to approx. 40-45 knots.

Second thing is to define the sizes in-between. Important to know: the wind pressure (which you feel in your hands) raises in square in relation to the wind speed. Therefore the smaller the sail size the smaller the size increments need to become. For large sails, the gap can be up to 1.5 sqm, while for very small sails it can go down to 0.3 sqm.

Taking all of this into account a typical quiver for our 75 kg guy could look as following:
7.3 - 6.0 - 5.3 - 4.7 - 4.2 - 3.7

Taking the “10 kg = 1 sqm” rule (see previous point) in consideration a typical quiver for an 85 kg guy could then be:
8.3 - 7.0 - 6.0 - 5-0 - 4.5 - 4.0
