How to make my own sail?
 
Im completly new to sailing and barley even know all the terms yet but have been reading as much as i can. The only thing ive sailed, or tried is my kayak that I used bamboo for the mast, and a broom stick for the boom and a tarp for a main sail... It was quite a sight i just wanted to see if i could figure out how to sail and now im obsessed. I now know a sail must be a specific shape in order to do more then sail down wind. I want to start with my kayak since i already have it, Ill need to make a mast, boom, main and head sail, the head sail can come later but I dont even know where to start.

I was going to use fiberglass tubing for a mast, probably 16 feet?
For the sail, Well you tell me how to start.. please
Then for the boom i was going to use a wood rod, and maybe find a way to roll it for reducing sail area.

I dont have lots of money to spend on a kayak sailing kit and all the ones I see have pretty small sails, My kayak is pretty stable but if i need to add outriggers i could id preffer something that could propel my kayak pretty nicely

Google making Polly tarp sails.
Making a Polytarp Sail for example.
As for a mast maybe wind surfer mast or other small boat mast would work.
Find a boat that is trashed and see if you can make a deal for the mast.

I have one you can have in CT if you happen to be driving through.

You can also buy, beg, borrow, or steal "Sailmaker's Apprentice", by Emiliano Marino. It has waaaayyyyyy more info than you need for your project, but it's also a pretty cool book to have around.

You can use Tyvek for making a sail. Its the stuff used in construction of houses. You will know when you see it. Making the Tyvek Sail and many other websites. The mast you are talking about seems way big .. Might take a look at some they sell and copy them. pvc pipe ? You might only need a main sail or only a jib. and
http://www.sailrite.com/ has every little accessory you need and sail material of almost every kind. Also, will help you with creative ideas.

There is a company that sells Tyvek in sufficeint size for small sails but I forget their name.
What you want to make is a Lateen (like a Sunfish) sail because it is "cut flat" meaning it has no curvature. A lateen rig is about the simplest way to put a sail on a small vessel. I made many for my homebuilt 12' MiniCup sailboats beginning with the duct taped version and finally sewing an overlap at the edges thru which I put grommets. These grommets were used with big zip ties to hold the sail to the spars. My latest sewn Tyvek sail has lasted for years.
For spars, I went to Metal Supermarket and bought thin walled Aluminum tubing for the two that carry the sail and a shorter piece of 1/8" wall for the short mast.
You might consider building a modern version of a MiniCup as the plans are free on the Stevenson Projects website. Somewhere out there, I think I still have my old site called MiniCup Madness about my adventures with them.

The company that sells the poly sails kits is Polysails Int. ant it is a good way to get sails for old small boats.
Again, I recc a lateen sail because it gives a huge amount of sail area using a short mast without any stays to hold the mast up and they are very easy to make.
A lateen sail has a mast and two spars that make a triangle with a vertex near the mast. The difficult part is joining these two spars so they can move in rrelation to each other. I put a wood plug in each spar with an eye bolt in each with the eyes joined. It is possible to reef a lateen sail and I have a design for this but have never implemented it. Sailing a small boat in strong wind is interesting. Always carry a paddle for when the wind dies.

And don't forget Sailcut CAD | Sailcut to design the sail and panels.

The lateen does look easyto make but is it possible to use a bermuda sloop? I would make it 10 feet high and have a 6 foot base, for 30 sf, then maybe add a head sail later, I just think it looks better then the lateen. Is there any special things involved in making a burmuda sloop? Is it just a triangle?

Special shapes are required. It is not just a triangle. "Sailmaker's Apprentice", by Emiliano Marino will tell you what you need to know to shape the sail properly and where to put the rig on the boat. Get it from the library.
