Master Sailmaker Gary Gleason
Gary Gleason has been designing and building custom sails since 1984 — and every sail still receives 100% of his attention. He consults with you, and when all the details are specified, his factory enters the sail into production. When you call Gleason Sails, you're talking to Gary.
From full-batten mainsails to asymmetrical spinnakers, Gary works closely with each sailor to understand their boat, their sailing style, and their goals — then designs a sail to match. His materials are sourced from Challenge Sailcloth in the USA, Dimension Polyant and Contender Sailcloth, both in Germany.
Every sail comes with a 3-year workmanship warranty and the confidence that comes from four decades of experience on the water. As your personal custom sailmaker, Gary ships finished sails nationwide — you can buy sails online through our quote form and have your custom sail delivered directly to your marina.

What Sailors Say About Our Custom Sails
★★★★★
"Gleason Sails exceeded my expectations with their custom design and exceptional quality. Gary took the time to understand exactly what I needed. Highly recommend!"
★★★★★
"Gary built a full-batten main for my J/29 that transformed how the boat sails. Better shape, less flogging, and it's already outlasted my old sail by years."
★★★★★
"I've bought sails from big lofts and from Gary. There's no comparison — the personal attention, the quality of the cloth, and the fit are simply better when Gary designs your sail."
