The Doyle 2+2 Mainsail has the ideal batten configuration for performance and
durability especially for offshore racing. The 2+2 batten configuration, that is 2 full
length top battens and 2 standard length lower battens provides a durable and versatile
performing sail.
The Layout Philosophy
For many years full batten mains have been the norm for cruising boats and offshore racing
boats and this continues to be true. The full length battens add overall durability to the
sail by reducing flogging, and contribute to supporting the mainsail fabric. Having all
the battens full length unnecessarily increases the weight of the sail and removes some of
the shape controlling ability through the lower portion. With full battens down low, the
ability to change the camber of the sail in that area is impaired by the stiffness of the
battens, and they also inhibit the reefing process. Longer than normal battens are used
through the reef area and are adequate to support the roach down low.
In the past the IMS rating system penalized boats with full length battens in their mains,
therefore it's been rare to see a top IMS racing boat with a full battened mainsail. PHRF
however, does not penalize for full battens and the majority of Doyle's PHRF racing mains
are 2+2 Mainsails. They are extremely high performance and durable with the short lower
battens being light and allowing for easy changes in sail shape.
The Doyle 2+2 Mainsail has a durability advantage provided by the stability of the full top
battens and the performance advantage of varying shape because of standard length lower
battens.
Do the Full Battens Have Trouble Going Up and Down the Mast?
With older sails and slide systems, people shied away from full length battens because
they would catch as the sail went up and down the luff track. With modern slides and sail
systems, this problem has been eliminated. Custom Doyle "Slip Slides" engineered
out of Nylotron, are self lubricating and much stronger than conventional slides. They are
economical and stop the battens from hanging up.
Conclusion...
The Doyle 2+2 Mainsail is the perfect solution for cruising or racing sailors, it is durable
yet high performance and easy to handle.
