The Powerhead is the right batten configuration for those who both cruise and race. No matter what construction option you choose, the Powerhead’s full-length top batten gives many of the durability benefits of a full-batten main while offering performance advantages for sailing faster upwind as well as downwind.

The Powerhead is a faster sail than a standard mainsail because the full-length top batten creates more roach. This extra area toward the top of the sail enables a more effective aerodynamical shape that allows a boat to point higher upwind and gives more sail area for sailing downwind.

The full-length top batten stabilizes the leech allowing UK to build a maximum-roach sail.  The long batten increases longevity by minimizing the damaging effects of luffing and by preventing the draft of the sail from moving aft over the years.  To support the large leech on lower aspect sails, UK Sailmakers also offers the option of making a second batten full length.

For lower aspect mainsails, UK Sailmakers offers the Powerhead with the top two battens full length to support the wider head section of the sail.
