Endurance Series sails are among Ullman’s most durable cruising products, developed for offshore and passage-making use. Reinforced high-load areas and material choices focused on longevity support dependable long-distance sailing.
Endurance Series
Each sail is designed for the individual yacht, sailing plans and budget, with balanced performance and straightforward handling as core priorities.
Mainsails include additional reinforcement in high-load reefing areas for extended periods of reduced sail area.
Roller-reefing genoas receive added strength at the head and tack to help limit distortion and support longevity.
Enduro Dacron prioritizes durability, while taffeta-coated Enduro Laminate provides a lighter, lower-stretch option for performance-minded cruisers.
The local loft selects cloth, construction and finishing to match the yacht, expected mileage, handling systems and cruising goals.
Endurance Series
Endurance is Ullman’s durability-focused offshore and passage-making range. Custom design, reinforced load areas and suitable cloth selection are combined for the yacht and cruising program.
Every sail is custom-designed for the yacht, crew and intended offshore use.
Mainsail reef zones and roller-reefing genoa head and tack areas receive additional reinforcement.
Enduro Dacron or taffeta-coated Enduro Laminate is selected to match durability, handling and performance priorities.
Woven Dacron may use cross-cut or radial construction; the laminate option is configured for the selected cloth and load plan.
Thread, hardware, UV protection and handling details are confirmed with the loft rather than assumed to be identical on every sail.
Endurance Series
Endurance sails are reinforced for offshore and passage-making use, with particular attention to reefing loads, roller-reefing headsails and seam construction.
Extra reinforcement is added in high-load mainsail reefing areas for the sustained loads associated with extended reefing.
Roller-reefing genoas receive added reinforcement at the head and tack to help limit distortion and improve longevity.
The official Endurance brochure specifies multiple rows of triple-step stitching on each seam as part of its durability-led construction.
UV protection, thread, hardware and handling details are selected for the boat and sailing area. GORE® TENARA® may be discussed where extended seam life is a priority.
Endurance sails share this verified profile; the final specification varies by yacht and sail:
Custom design for offshore or passage-making use
Enduro Dacron or taffeta-coated Enduro Laminate
Multiple rows of triple-step stitching on each seam
Additional reinforcement in mainsail reefing areas
Head and tack reinforcement on roller-reefing genoas
Hardware, UV protection and finishing specified per project
Endurance Series
Endurance sails are custom projects. These are configuration decisions to make with the local Ullman Sails loft.
Choose a durable woven polyester construction or a lighter, lower-stretch, taffeta-coated cruising laminate.
The official brochure lists cross-cut and radial options for woven Dacron; suitability depends on the sail and project.
Reef layout and reinforcement are determined by the mainsail, expected conditions and the owner’s passage-making plans.
Headsail design, reinforcement and UV protection are matched to the furling system and expected use.
Where specified, this ePTFE thread resists UV, saltwater and extreme weather; confirm its use and extent with the loft.
Hardware, battens, slides and finishing are custom choices and should be documented in the individual sail quotation.
GORE® TENARA® is an ePTFE sewing thread intended for long-lasting outdoor and marine seams. Its use and extent on an Endurance sail must be confirmed in the individual specification.
Gore states that the thread does not absorb water and maintains its strength under regular exposure to sunlight’s UV rays.
It also resists saltwater, extreme weather, acid rain and many cleaning chemicals, making it relevant where seam life is a priority.
Thread selection does not replace proper sail care or inspection; discuss the appropriate thread and construction with the local loft.
