Our HighTech Cruising -line was originally designed for the exceptional needs of single handled sailors. These sails offer great performance with no concessions to durability and lastingness. Numerous details like - radial panel layout - large stress-aligned corner patches and - foam core / tapered battens make these sails the best on the market. They tolerate a lot of use and abuse, which is important when sailing at open waters with a small crew. The base of our HighTech Cruising -line is a full-batten mainsail and a roller-furling genoa both made of Radial Wide Dacron cloth. In boats over 40 feet we also use stronger DC-taffeta/Mylar and ACL Mylar cloth, which is soft but tough. By using a radial panel layout the number of horizontal seams is brought down to only two, which considerably reduces the risk of breakage. The horizontal seams are prone to wear and tear and most breakage start from a worn seam. A radial cut sail retains Its designed shape on a wide wind range. The sail requires less trimming and the boat heels less because the flow remains in the front of the sail as designed.
