The DL SAILS MULTI HULL SQUARE TOP MAINSAIL are designed with a special simulation program, the specific characteristics and take into account the elements of the boat and the conditions required.  A square-top mainsail increases sail area aloft without requiring a taller mast.
It provides more power and better performance, especially in light to moderate winds.
Square-Top Design:The head of the mainsail is squared off rather than triangular, providing more sail area aloft.
The increased area at the top improves performance, especially in light to moderate winds.
Typically supported by a full-length top batten and additional battens below for shape and stability.
Multi-Hull Adaptation:Designed to suit the high speeds and low drag characteristics of multi-hull vessels.The sail is often cut to match the wider apparent wind angles experienced by multi-hulls.
Full-length Round battens and special adjustment systems are common to support the larger roach (curvature) and maintain sail shape.
Battens also help in better reefing and flaking of the sail.
Flat Shape DL SAILS Multihulls have less heeling compared to monohulls, which allows for flatter sails to maximize forward drive and reduce drag.
Flat sails are also easier to handle in stronger winds.
High Aspect Ratio: Many multihull mainsails have a high aspect ratio (taller and narrower) to reduce drag and improve upwind performance.
