White Polytarp Sails and Kits

PolySail International

Low-Cost/High Performance Sails and Kits for Sailors, Boat Builders, and Independent Thinkers

































PolySail International has been supplying low-cost, high performance poly laminate* sails and sailmaking kits to home boatbuilders and small boat sailors since 1996. Our experience with poly sailmaking and with poly laminates for sail materials for sailboats, catamarans, canoes, and kayaks is unrivaled.  And, as our research, real-world testing, and continuing customer feedback indicate, the PolySails we construct do not fail or fail to impress with their durability, appearance, and performance. With two PDRacer World Championships in the last three years, numerous finishes in the Texas 200, and entries in the grueling Everglades Challenge and NC Pamlico Sound 300, our high-priced competitors are beginning to take notice of our high performing, durable, and inexpensive sails.



The Crystal River Boat Builders and the Crystal River State Park chose PolySail International to furnish the sails for their recently completed scow “Spirit”—a Civil War era replica of a boat often used as a blockade runner along the Florida Gulf Coast. “Spirit carries 642 sq. ft. of PolySails and boasts a speed of 8 knots in tests both inland and on the open ocean.

Landreville12Canadian Rick Landreville powers to victory in the second of three races that he won handily at the 2013 PDRacer World Championship at Port Alberni, Canada. Rick was flying a 90 sq. ft. PolySail racing lug that proved ideal for the light airs of the saltwater bay where the 2013 event was held.









This photo of PolySail-powered traditional Haitian fishing boats sailing on the bay of Cap Haitien shows a few of the many colorful sails that we have provided for the Alfred Beliard Foundation’s Sail Replacement and Fundraising Project for the sustenance level fishermen/sailors of the local fishing village. Each sponsored sail helps provide funds for numerous events and projects that enhance the fleet, the beaches, and the local economy.

Advantages to the sailor of our stronger, U-V protected poly laminate material:

1.       Low cost and ease of replacement (Our kits start at $64.95)

2.       Strength and light weight (We’ve climbed onto one of our small triangular sails suspended from the three corners to see if it would stretch out of shape. It didn't.)

3.       Resistance to water, rot, and sunlight (We've used our white poly laminate for boat covers for in South Florida for four years. Unlike most tarps, they don't disintegrate in a season or two.)

4.       Safety factor (Unlike most sail materials, poly laminate sails float because they are about 10% less dense than water making it difficult for a boat equipped with PolySails to turn upside down.)

5.       Speed and simplicity of construction (Poly laminate sails can be taped rather than sewn, but the material sews easily if you want to reinforce edges and corners, add battens, include windows, or sew around the perimeter as the adhesives eventually loosen.)

6.       Opportunity to experiment with different sail shapes, colors, and sizes (See our library and sail database for both our generic PolySail construction guide and specific directions for building many specific types of sails.)

7.       Appearance and performance that rivals Dacron sails (While we know of few head-to-head comparisons, we know that you won’t be embarrassed by sailors flying similar sails that are made professionally from Dacron or other sail materials based on the few competitions we do know about. Often it’s the other guy that gets embarrassed.)

8.       Perfect for low budget group or community boatbuilding projects (Because of their low cost, one nonprofit uses our sails for fundraising purposes. By selling sponsorships and advertising for each set of sails in the fleet, the non-profit realizes about $500 profit on each sail.)
