How to define the sails for a ship of high performance

How to define the Sails for a ship of high performance of 5 meters whose the total weight of the sailing ship 300 kg ? and had it accommodated on board at the most 3 people in the total of 240 kg more?

 

How many square meters of sails do I need for me to plane a sailing ship of high performance with 600 kg of total weight with peoples on board?

 

Its really more about how large sails can you hold up in the weather you will commonly be sailing in. There is a lot in Bethwaite in this sort of area.

 

It depends on the force.


The force of the wind
The force of the drag

 

Type about 15 knots for example

 

Some facts

I've used the figure of 500 sq. ft.(46.4 sq. m) /per metric ton(2200lb.) for the power required to plane- I think I found it in Marchaj a long time ago. There is a formula: Displacement in lb.'s divided by( LWL waterplane area in sq.ft. times waterline length in feet) which gives a figure that should provide some degree of planing up to 1.5 (I14 about 1.22)-with enough power. From Sailing Yacht Design by Douglas Phillips-Birt.
Pierre Gutelle in "Design of Sailing Yachts" has a whole chapter on planing.
This site is invaluable for all the statistics it provides on high performance boats in the range you're looking at:

Good luck and do as much research as possible.

 

Thank you Doug, through of that site I will have
a good reference and with that I will apply in my project .
