Stratis GPC performance cruising sails have
been developed to deliver the rugged
durability required of cruising sails that are
folded or furled, while maintaining many of the
performance benefits of racing sails.
GPC is the tough alternative to a performance film sail without the
performance decrease commonly experienced from a standard panel
construction, or from a laminated sail cloth produced by an external
Because of the variety of fibres that can be selected, Stratis GPC is
equally well suited to superyachts as it is smaller cruising yachts.
The use of a wide variety of different fibre combinations or even single
use fibres allows us to custom build each sail to a particular
The fibres that Doyle use in Stratis GPC laminates are typically
Polyester, Vectran, Technora and medium to low modulus carbon.
These fibres are used in conjunction with specific resins which are
selected for their long term durability and resistance to high humidity
and wet conditions
External taffetas can be specified on either or both sides of the
membranes depending on requirements for scuff-resistance.
GPC laminates can also incorporate added compression and primary
yarns to fully address the issues associated with roller furling sails.
Custom reef points built into the laminates also help improve
performance through a wide range of conditions.
Whether your boat is
a sailing dinghy or a
56 metre superyacht;
we can engineer the ideal sail to suit your needs.

PEN is the big brother of PET. It was invented very shortly after PET but only commercialised in the 1990’s after Amoco started the first plant to produce the NDA needed to make it affordable in commercial quantities.
Technora is also made by Teijin, the manufacturers of Twaron, and is a closerelative of PPTA. It is a copolymer, which means it is comprised of two different building blocks instead of just one. The second component that is added to the structure introduces a regularly repeating kink in the...
ICE is an entirely new and unique UHMWPE (Ultra High Molecular Weight Polyethelene) fibre, developed by the Doyle Stratis team following market demand for a creep free and highly durable sail membrane.
