A generally triangular-shaped, radial-cut sail intended for use with a small sailing craft such as a Laser™ Class sailboat. A mast sleeve or “luff tube” is arranged or formed adjacent the luff area of the sail, extending from the head to the foot, and sized to accommodate a flexible mast formed of two or more mast sections. A luff tube patch is placed on the leading edge of the mast sleeve adjacent a point where the mast sections meet when the sailing rig is assembled.

1. A sail having a generally triangular shape, with a head portion at a top, a foot portion at a bottom, a tack portion at a forward end of the foot, a clew portion at an aft end of the foot, and a tuff portion extending from the head to the forward end of the foot, the sail further comprising: a pl
1. A sail having a generally triangular shape, with a head portion at a top, a foot portion at a bottom, a tack portion at a forward end of the foot, a clew portion at an aft end of the foot, and a tuff portion extending from the head to the forward end of the foot, the sail further comprising: a plurality of bi-radially cut panels, the panels generally arrange as an upper radial section and a lower radial section, the upper radial section comprising some of the plurality of panels, and the lower radial section comprising other ones of the plurality of panels, with the panels forming the upper radial section and the lower radial section overlapping along a longitudinal seam;the panels in the upper radial section generally running from the longitudinal seam to the head, and the panels in the lower radial section generally running from the clew to the longitudinal seam and to and to a lower portion of the luff;a luff tube attached along the tuff, the tuff tube shaped to accommodate a mast formed of two mast sections that fit together at a mast joint;the longitudinal seam extending to a location on the luff tube above the mast joint;a tuff tube patch disposed on the luff tube adjacent the luff, the longitudinal seam and the mast joint; andfurther wherein the luff tube has a cut-out in a center portion thereof, and the luff tube patch is positioned over the cut-out. 2. The apparatus of claim 1, wherein the top radial section comprises four radial cut panels. 3. The apparatus of claim 1, wherein the bottom radial section comprises at least eight radial cut panels. 4. The apparatus of claim 1, wherein at least one of the head, clew or tack are reinforced by additional pieces of sail cloth overlapping at least two of the adjacent radial panels. 5. The apparatus of claim 1, wherein the tack includes an additional panel attached to both the tack and the luff tube at a lower portion of the luff tube. 6. The apparatus of claim 1 wherein the panels in the lower radial section increase in thickness with distance from the clew towards the luff. 7. A sail having a generally triangular shape, with a head portion at a top, a foot portion at a bottom, a tack portion at a forward end of the foot, a clew portion at an aft end of the foot, and a tuff portion extending from the head to the forward end of the foot, the sail further comprising: a plurality of bi-radially cut panels, the panels generally arranged as an upper radial section and a lower radial section, the upper radial section comprising some of the plurality of panels, and the lower radial section comprising other ones of the plurality of panels, with the panels forming the upper radial section and the lower radial section overlapping along a longitudinal seam;the panels in the upper radial section generally running from the longitudinal seam to the head, and the panels in the lower radial section generally running from the clew to the longitudinal seam and to a lower portion of the luff;a luff tube attached along the luff, the luff tube shaped to accommodate a mast formed of two mast sections that fit together at a mast joint;the longitudinal seam extending to a location on the luff tube above the mast joint;a luff tube patch disposed on the luff be adjacent the luff, the longitudinal seam, and the mast joint; andfurther wherein the longitudinal seam is attached to a top portion of the luff tube patch. 8. The apparatus of claim 7, wherein the luff tube patch is further aligned with the longitudinal seam such that the luff tube patch is located on the luff tube below where the longitudinal seam extends to the luff tube.
